The radius of the spherical ball is 4.32_+0.01m.what does it mean?
The estimated error rate for spherical volume measurements is 0.694%.Percent error is the difference between the estimated value and the actual value compared to the actual value, expressed as a percentage. So the percent error is the relative error multiplied by 100.
To calculate the Percent error
Subtract the actual value from the estimated value
Divide the result from step 1 by the actual value
to get the total percentage Multiply the result by 100
Formula,
Error Rate = ((Estimated Number – Actual Number)/Actual Number) x 100
from the given data
V=(4/3)πr3
=337.53cm³
so
((339.87-337.53)/337.53)x100

What do you mean by Energy?The capacity to perform work is known as energy in physics. Potential, kinetic, thermal, electrical, chemical, nuclear, and other types are all possible. As energy is transferred from one body to another, there is also heat and work. Energy is always categorized after it has been transferred based on its nature. As a result, heat transfer may result in thermal energy, whereas labor done may result in mechanical energy.
Motion is a common feature of all energy types. Whenever a body is in motion, for instance, it contains kinetic energy. Even while at rest, a tensioned object like a spring or bow has the ability to move; this is because of the configuration of the object, which carries potential energy. Nuclear energy is similar in that it has potential energy.

If a cannonball were launched with a speed of 35m/s at a 50° angle from the height of 0m, what would be the cannonball's range?
The range of a cannonball launched with a speed of 35 m/s at an angle of 50 would be 119.1 meters.
The launching of a cannonball is a case of projectile motion.
The formula for the range(R) of a projectile is
R = 2 u² sin(θ) cos(θ)/g
Here,
u = initial speed with which the projectile is launched = 35 m/s
θ = Angle at which projectile is launched = 50°
R = 2 (35)² sin(50) cos(50)/ 9.8
R = 2 x 1225 x 0.76 x 0.64/9.8
R = 119.1 m

A rectangular tank is filled with water to a depth of 4m. Calculate the pressure at the bottom of the tank. PLEASEEE HELP!!
The pressure in a liquid at a given depth is called the hydrostatic pressure. This can be calculated using the hydrostatic equation:
P = ρgh
P = (1000 kg/m³)(9.8 m/s²)(4 m)
P = 39200 PaAnswer:
P = ρgh
P = (1000 kg/m³)(9.8 m/s²)(4 m)
P = 39200 Pa
Explanation:
In the case of the water stored in a tank, the pressure at its bottom is the weight acting on a unit area of the surface where the tank is kept. To turn that into an equation: Pressure = weight/area, and weight = mass (m) * acceleration due to gravity (g). This means pressure = m * g/ area

When the body of mass m is projected at angle θ, the displacement is horizontal to the earth's surface, but the force of gravity is perpendicular to the motion of the body.
Therefore, the gravitational force on the body is zero.
Work done will also be zero due to zero gravitational force.
Displacement can be defined as the shortest distance covered by the object or it is the change in the position of the object.
Therefore the average power i.e. P = (Work/Time) of gravitational force over the whole time of flight is zero.

good morningWhat is the difference between a neutralization reaction and a double-displacement reaction? (1 point) Double-displacement reactions are always redox reactions. Double-displacement reactions always involve acids and bases. Neutralization reactions always produce water and a salt. Neutralization reactions are always combustion reactions.
Answer:
Neutralization reactions always produce water and a salt.
Explanation:
There are different types of chemical reactions that occurs. Two of them are neutralization and double-displacement reaction. Neutralization reaction is the reaction between an acid and a base to give an acid salt and water as products. For example:
2NaOH (base) + H2SO4 (acid) → Na2SO4 (salt) + 2H2O (water)
On the other hand, Double displacement reaction is the reaction that involves an ion exchange between the reactants to form new products. This ionic exchange occurs in such a way that two reactants form two new products. For example:
2NaCl + Ca(NO3)2 → CaCl2 + 2NaNO3
Therefore, the major difference between these two types of reactions is that: NEUTRALIZATION MUST ALWAYS PRODUCE WATER AND SALT AS PRODUCTS.

A particle with electric charge q moves along a straight line in a uniform electric field →E with speed u . The electric force exerted on the charge is qE . The velocity of the particle and the electric field are both in the x direction..(c) What If? If the particle starts from rest at x=0 at t=0 , how would you proceed to find the speed of the particle and its position at time t ?
A physical field called an electric field surrounds electrically charged particles and attracts or repels all other charged particles nearby. The physical field of a system of charged particles can also be referred to as the electric field.
In a uniform electric field E, a particle with electric charge q moves in a straight line. The speed of the particle is u.
The electric force exerted in the charge is qE.
The electric field and the velocity of the particle are both in the x direction.
Now,
The particle starts from rest i.e. x = 0 and t = 0.
We have the acceleration of the particle as:
a = (du/dt) = (qE/m) (( 1 - (u²/c²) )⁻³/²
Now,
du/ (( 1 - (u²/c²) )⁻³/² = (qE/m) t
Integrating the above equation with limits for x as 0 to u and for t as 0 to t.
We get,
u/(1 - (u²/c²))^{-1/2} = qEt/m
Therefore,
u = (qEct)/[√(m²c² + q²E²t²)]
For the position of the particle:
The position of the particle will be the integration of the speed of the particle in t = 0 to t = t.
Therefore,
x = ∫udt
x = qEc∫ tdt/(√(m²c² + q²E²t²) )
x = (c/qE) ( √(m²c² + q²E²t²) - mc)

Owen throws the ball to Dina at 0.800 c (according to Owen), and their separation (measured in S' ) is equal to 1.80 × 10¹²m .(b) According to Dina, what time interval is required for the ball to reach her? According to Ed.
The total time taken by the ball to reach Dina is 7.5 × 10³ s.
A frame of reference is a set of reference points—geometric points whose positions are known mathematically and physically—that define the origin, orientation, and scale of an abstract coordinate system.
If a body does not continuously adjust its position in relation to its environment throughout the course of time, it is said to be at rest.
In the frame S', Dina and Owen are at rest.
The speed of the ball with respect to Owen, u =0.800c
The speed of the frame S' with respect to frame S, v = 0.600c
Distance between Dina and Owen, L(p) = 1.8 × 10¹² m
Speed of light, c = 3 × 10⁸ m/s
Therefore, the ball reaches Dina in time:
t = L(p) / u
t = 1.8 × 10¹² m / 0.8c
