A crane must exert a force of 25000 N to lift a whale shark, the largest fish in the world, into a tank. If the shark’s acceleration equals 1.25 m/s2, what is the shark’s mass?
The force required to lift the whale shark is given as 25000 N, and its acceleration is 1.25 m/s^2. We can use Newton's second law of motion, which states that the force (F) applied on an object is equal to the product of its mass (m) and acceleration (a), i.e. F = ma.
Rearranging the equation to solve for the mass, we get:
m = F/a
Substituting the given values, we get:
m = 25000 N / 1.25 m/s^2
m = 20000 kg
Therefore, the mass of the whale shark is approximately 20,000 kg.
Identify What limits the speed at which the ball will leave the racket?
The maximum speed at which the racket can move is limited by the physical ability of the player.
What limits the speed at which the ball will leave the racket?The speed at which a ball leaves a racket is determined by several factors, including the speed of the racket at impact, the angle of the racket face, and the properties of the ball itself.
The maximum speed at which the racket can move is limited by the physical ability of the player. A player can only swing the racket so fast before they reach their physical limits. Additionally, the angle at which the racket strikes the ball affects the ball's speed. If the racket face is angled too steeply or too shallowly, it can decrease the speed of the ball.

A lorry of mass 8 000 kg travelling at 20 m s¹ collides with a car of mass 1 000 kg that parked at the side of the road. After the collision, the lorry and the car move together. Calculate the velocity after the collision.
Answer:
Explanation:
Before the collision, the lorry has a momentum of:
p1 = m1v1 = 8000 kg * 20 m/s = 160000 kgm/s
where m1 is the mass of the lorry and v1 is its velocity.
The car is initially at rest, so its momentum is:
p2 = m2*v2 = 0
where m2 is the mass of the car and v2 is its velocity.
After the collision, the two vehicles move together with a common velocity v. The total momentum of the system after the collision is:
p = (m1 + m2)*v
where m1 + m2 is the total mass of the system.
By the law of conservation of momentum, the total momentum before and after the collision is the same. So we have:
p1 + p2 = p
Substituting the values we have:
160000 kg*m/s + 0 = (8000 kg + 1000 kg)*v
Simplifying:
v = (160000 kg*m/s) / (9000 kg)
v = 17.78 m/s
Therefore, the velocity of the lorry and car together after the collision is 17.78 m/s.
Of the following expressions, which ones give the correct torque produced by the force f→ around point p ?

A constant force is applied to an object, causing the object to accelerate at 6. 00 m/s2. What will the acceleration be if
The rate of acceleration if force is doubled is same, if the objects mass is doubled it is halved, if both the object mass and force are doubled the acceleration will be same , d- acceleration will be quadrupled
Newton's second law of motion states that force is equal to mass multiplied by acceleration: F = m * a, where F is the applied force, m is the object's mass, and an is the acceleration produced.
a- When the force is doubled, the acceleration doubles as well. Using the formula, we get:
F' = 2F
a' = F' / m = (2F) / m = 2F / (2m) = F / m = a
B- If the mass is doubled, the acceleration will be halved. Using the equation, we get:
m' = 2m
a' = F / m' = F / (2m) = a / 2
C- If both the force and the mass are doubled, the acceleration will remain the same. Using the equation, we get:
F' = 2F
m' = 2m
a' = F' / m' = (2F) / (2m) = F / m = a
D- If the force is doubled and the mass is halved, the acceleration will be quadrupled. Using the equation, we get:

where r2 = 1.20 - 0.800 = 0.400 m.
F2 = (9.0 x 10^9) * (-6.50 x 10^-9) * (-1.60 x 10^-19) / (0.400)^2

The net electric force on the electron is again the vector sum of these two forces:
Fnet = F1 + F2
= (7.20 x 10^-14)+ (2.88 x 10^-14 N) = 4.32x 10^-14N
The electric force is a fundamental concept in physics that describes the attractive or repulsive interaction between electrically charged particles. This force is a fundamental force of nature, meaning that it cannot be explained in terms of other forces.
The electric force is directly proportional to the magnitude of the charges on the particles and inversely proportional to the square of the distance between them. This means that as the charges on the particles increase, the electric force between them also increases. However, as the distance between the particles increases, the electric force decreases.
The electric force plays a crucial role in a wide range of phenomena in physics, including the behavior of electrically charged particles in electric fields, the operation of electric motors and generators, and the behavior of electrically charged particles in the human body.

a.) 30
b.) 19
c.) 0.05
d.) 7
Answer:
We can use the formula for the transformer voltage ratio, which states that the ratio of the number of turns in the primary coil to the number of turns in the secondary coil is equal to the ratio of the output voltage to the input voltage:
Np/Ns = Vp/Vs
where Np is the number of turns in the primary coil, Ns is the number of turns in the secondary coil, Vp is the input voltage, and Vs is the output voltage.
We know that Vp = 220 V and Vs = 140 V, and we are trying to find Ns. We also know that Np = 30, since that is the number of turns in the primary coil. Substituting these values into the formula, we get:
30/Ns = 220/140
Simplifying the right side of the equation, we get:
30/Ns = 11/7
Cross-multiplying, we get:
11Ns = 210
Dividing both sides by 11, we get:
Ns = 19
Therefore, the answer is b.) 19.

For air, C,-0.177 cal/g °C. Suppose that air is confined to a cylinder by a movable piston under a constant pressure of 3.0 atm. How much heat must be adde quticmtucs
The heat needed for the air to change from 27°C to 400°C is 291 J.
How to calculate specific heat capacity?First, calculate the final volume of the air using the ideal gas law:
PV = nRT
where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature.
Assuming that the pressure remains constant, rearrange the ideal gas law to solve for the final volume:
V₂ = (nRT₂) / P
where T₂ is the final temperature.
Calculate the initial number of moles of air using the ideal gas law with the original conditions:
n = (PV) / RT₁
where T₁ is the initial temperature.
Substituting the given values:
n = (3.0 atm x 5860 cm3) / (0.0821 L atm/mol K x 300 K)
n = 0.72 mol
Now calculate the final volume:
V₂ = (0.72 mol x 0.0821 L atm/mol K x 673 K) / (3.0 atm)
V₂ = 13.47 L
The change in volume is therefore:
ΔV = V₂ - V₁
ΔV = 13.47 L - 5.86 L
ΔV = 7.61 L
To calculate the heat required, use the equation:
q = nCvΔT
where ΔT is the change in temperature.
Substituting the given values:
q = (0.72 mol x 0.177 cal/g °C x (400°C - 27°C))
q = 69.7 cal
Finally, convert this to joules:
q = 69.7 cal x 4.184 J/cal
q = 291 J
Therefore, the amount of heat that must be added to the air is 291 J.

The horizontal constricted pipe illustrated in the figure (a Venturi tube), can be used to measure flow velocities in an incompressible fluid. The ratio for the cross section areas of A2/A1 =0. 46, the difference in the pressure is Pi - P2 = dP = 27. 6 Pa, and the density of the fluid is 2. 93 kg/m. Find the speed of the fluid near the right hand end of the tube (i. E. , find v2
The speed of the fluid near the right-hand end of the tube is approximately 10.06 m/s.
What is Bernoulli's equation?Bernoulli's equation is a fundamental principle in fluid mechanics that relates the pressure, velocity, and height of a fluid in a flow. It states that for an incompressible fluid flowing in a steady state through a pipe of varying cross-sectional area, the total energy of the fluid (consisting of pressure energy, kinetic energy, and potential energy) remains constant along any streamline of the flow. Mathematically, the equation is:
P + (1/2)ρv² + ρgh = constant
To find the speed of the fluid near the right-hand end of the tube, we can use the Bernoulli's equation, which relates the pressure and velocity of a fluid in a flow:
P₁ + (1/2)ρv₁² = P₂ + (1/2)ρv₂²
where P1 and v1 are the pressure and velocity of the fluid at the left hand end of the tube (where the pipe is wider), and P2 and v2 are the pressure and velocity at the right-hand end (where the pipe is narrower).
We can redo this equation to solve for v₂:
v₂ = sqrt(2*(P₁-P₂)/ρ + v₁²)
where sqrt denotes the square root.
Using the given values:
A₂/A₁ = 0.46
dP = 27.6 Pa
ρ = 2.93 kg/m³
We can find the pressure at the left hand end using the fact that the pressure is the same at the same height, and the fluid is incompressible, so its density is constant:
P₁ = P₂ + dP = P₂ + 27.6 Pa
The area ratio gives us:
A₂ = 0.46*A₁
Now we need to find v₁. We can use the continuity equation, which states that the mass flow rate (ρAv) is constant in an incompressible fluid:
ρ₁A₁v₁ = ρ₂A₂v₂
where ρ1 is the density of the fluid at the left hand end, which is the same as ρ₂, and A₁ and A₂ are the pipe's cross-sectional areas at the left and right ends, respectively.
Substituting A₂ = 0.46 × A₁ and simplifying, we get:
v₁ = (0.46)² × v₂
Substituting this into the Bernoulli's equation, we get:
P₁ + (1/2)ρv₁² = P₂ + (1/2)ρv₂²
Substituting P₁ = P₂ + 27.6 Pa and v₁ = (0.46)² × v₂, and solving for v₂, we get:
v₂ = √((227.6)/(0.46^2ρ) + (0.46)⁴ × v₂²/ρ)
Simplifying this equation, we get:
v₂= √((227.6)/(0.46^2ρ × (1-0.46⁴)))
Substituting the given values, we get:
v₂ = √((227.6)/(0.46²²°⁹³ × (1-0.46⁴))) = 10.06m/s

Find the corresponding electric field vector in phasor-form. Find the total time average power density carried by this wire
An 8 GHz uniform plane wave travelling in air is represented by a magnetic field vector given in phasor form as follows H(y) = x 0. 015e^-j beta y + z 0. 03e^j(pi - beta y) mA - m^-1 . The total time-averaged power transferred to each eardrum in 1.0 second is 3.972x10^-7 J.
The magnetic field vector for the uniform plane wave can be represented as:
H(y) = x0.015e^(-jβy) + z0.03e^(j(π-βy)) mA/m
where β is the propagation constant, and has units of rad/m.
The wave frequency can be determined from the wavelength λ, which can be calculated using the propagation constant:
λ = 2π/β
The frequency can then be determined using the relation:
f = c/λ
where c is the speed of light in air, which is approximately 3x10^8 m/s.
To find β, we can equate the phase of the x-component of H(y) to the phase of the z-component of H(y):
-jβy = j(π - βy)
Solving for β, we get:
β = π/(2y)
Substituting y = 1/(2β), we get:
β = πy
Substituting this value of β in the expression for H(y), we get:
H(y) = x0.015e^(-jπy) + z0.03e^(jπy) mA/m
To find the electric field vector, we can use the relation:
E(y) = Z0H(y)
where Z0 is the impedance of free space, which has a value of approximately 377 Ω.
Substituting the values of H(y) and Z0, we get:
E(y) = x5.655e^(-jπy) + z11.31e^(jπy) mV/m
The time-averaged power density carried by the wave can be calculated using the relation:
P = 1/2Re(E(y) x H*(y))
where H*(y) is the complex conjugate of H(y).
Substituting the values of E(y) and H(y), we get:
P = 1/2(0.015)(5.655)(cos(πy) + jsin(πy)) + 1/2(0.03)(11.31)(cos(πy) - jsin(πy))
Simplifying, we get:
P = 0.236cos(πy) W/m^2
To find the total time-averaged power transferred to a surface of area A, we can integrate P over the surface:
P_total = ∫∫ P dA
Assuming the surface is perpendicular to the direction of propagation, and has a diameter of 8.4 mm, we get:
A = π(0.0042)^2 = 5.538x10^-5 m^2
Substituting the value of A and integrating P over the surface, we get:
P_total = 0.236∫∫ cos(πy) dA
P_total = 0.236cos(πy)∫∫ dA
P_total = 0.236cos(πy)(5.538x10^-5)
Substituting the value of y = 30 m, we get:
P_total = 0.236cos(πx30)(5.538x10^-5) = 3.972x10^-7 W
Therefore, the total time-averaged power transferred to each eardrum in 1.0 second is 3.972x10^-7 J.

How much energy is wasted during a fall?
When an object is falling freely, its velocity rises because of the acceleration caused by gravity. In the instance of a body that is falling freely, the kinetic energy thus rises while the potential energy falls as the height of the object decreases.
When an object is descending at its terminal velocity, the force of gravity and air resistance are equal, and the object no longer accelerates. The amount of labor done is equal to the sum of the object's displacement and the gravitational force. The modification of the object's potential energy brought on by gravity can also be used to calculate it.

An electron moves in a circular path with a radius of 0.20 m at a constant speed of 1.5 X 105 m/s. What is the period of its motion?
Answer:
V = 2 π R / T speed V where T is period
T = 2 π R / V = 2 π * .2 m / 1.5E5 m/s = 8.38E-6 sec
Period = 8.36 * 10-6 sec
On August 21, 2017, the United States experienced the first coast to coast solar eclipse since 1918. How were the sun, moon, and Earth arranged during this eclipse?
The biggest celestial event of the decade will likely take place on August 21 when a total solar eclipse crosses the whole continental United States from coast to coast.
Arrangement This is the first time since 1918 that the US visit will experience a total solar eclipse, which is brought on by the Moon moving in front of the Sun. In order to see the Sun's disc totally covered by the Moon, people are swarming to the cities that are closest to the eclipse's path. Even if you're not in the path, the US will still put on a spectacular show since on August 21, the majority of the Sun will be hidden in clouds in every state in the lower.For more information on solar eclipse kindly visit to

What is the charge of one elementary charge?A single electron or proton's electric charge is referred to as an elementary charge. It is a fundamental physical constant with a magnitude of approximately 1.602 x 10-19 coulombs (C). Electric charge is quantized using the elementary charge, which is thought to be the smallest amount of electric charge that can exist in nature. The elementary charge is the same for both particles because protons and electrons have the same and opposite charges. The behaviour of atoms and molecules is greatly influenced by their elementary charge, which also determines their electronic structure and affects how they interact with other charged particles in their environment.

Fill in the blanks in the following paragraph to correctly identify four principles of the second law of thermodynamics. (1 point) Change in the internal energy of the system= -130 J Isobaric process is a thermodynamic process that takes place under constant pressure. Temperature, volume, and internal energy are not constant in this process, even though the pressure is constant. ☝️ An adiabatic process is defined as a process in which no heat transfer takes place. This does not mean that the temperature is constant, but rather that no heat is transferred into or out from the system. Heat naturally flows from an object that has a _______________ temperature to an object that has a _______________ temperature. Heat can be made to flow in the reverse direction if _______________ is done. A machine can never have an efficiency of _______________. This means that heat energy can never be fully converted into _______________ energy.
Heat naturally flows from an object that has a high temperature to an object that has a low temperature. Heat can be made to flow in the reverse direction if temperature is done. A machine can never have an efficiency of fuel . This means that heat energy can never be fully converted into mechanical energy.
What is temperature ?
The movement of these particles likewise increases with rising temperature. A thermometer or a calorimeter are used to measure temperature.
What is kinetic energy ?
When an item undergoes work—the transfer of energy—by being subjected to a net force, it accelerates and acquires kinetic energy.
Therefore,Heat naturally flows from an object that has a high temperature to an object that has a low temperature. Heat can be made to flow in the reverse direction if temperature is done. A machine can never have an efficiency of fuel . This means that heat energy can never be fully converted into mechanical energy.
