What is the displacement of a car which travels at a steady velocity of
60 km/h
(a) for 3 h
(b) for 1/2 h?
Answer:
(a) 180 km
(b) 30km
Explanation:
To find displacement (in this case, kilometers) you need to convert km/h to km, this can be done by multiplying by the amount of hours:
[tex]\frac{60km}{h}*3h=60km*3=180km \\\frac{60km}{h} *h/2 = 60km/2=30km[/tex]
(The h/2 term came from 1/2*h, since half an hour is h*1/2)
A 1kg cart is accelerating at 2 m/s2 due to a constant force. If that same net force was applied to a cart with twice as much mass, what acceleration would it have?
Answer:1m/s2
Explanation:
What is the acceleration of a 7 kg mass pushed by a 3.5 N force?
Answer:
According to Newton's second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . This equation for acceleration can be used to calculate the acceleration of an object when its mass and the net force acting on it are known

A child rides a bicycle in a circular path withí a radius of 3.0 m. The
tangential speed of the bicycle is 2.0 m/s. The combined mass of the bicycle and the child is 43 kg.
Answer:
57.3N
Explanation:
Given parameters:
radius of the path = 3m
tangential speed = 2m/s
mass of the bicycle and child = 43kg
Unknown:
centripetal force = ?
Solution:
The centripetal force is the inward force on a body round a circular path.
It is expressed as;
F = [tex]\frac{mv^{2} }{r}[/tex]
F is the centripetal force
m is the mass
v is the tangential speed
r is the radius
F = [tex]\frac{43 x 2^{2} }{3}[/tex] = 57.3N
two particles, one with charge −3.77 μc and one with charge 6.91 μc, are 5.84 cm apart. what is the magnitude of the force that one particle exerts on the other?
The magnitude of the force that one particle exerts on the other = [tex]6.8644 \times 10^{13}[/tex] N
Charge of one particle,[tex]Q_1[/tex] = -3.77 μC
Charge of the other particle,[tex]Q_2[/tex] = 6.91 μC
The opposite signs of the charges implies the presence of force of attraction between the particles.
Given distance between particles, r = 5.84 cm = 0.0584 m
Coulomb's law states that the magnitude of the force exerted between two particles is directly proportional to the product of magnitude of charges of the particle and inversely proportional to the square of the distance between the particles.
From this we can infer the equation, [tex]F=\frac{kQ_1Q_2}{r^2}[/tex]
where F is the force between the particles and k =[tex]9\times 10^9 Nm^2C^{-2}[/tex] is the Coulomb's Constant.
So F = (9 x 10^9 x 3.77 x 6.91)/(0.0584 x 0.0584)
= [tex]6.8644 \times 10^{13}[/tex] N

Safety belts protect people in cars in the event of an accident because, according to Newton’s laws of motion, when an impact causes the car to suddenly change its motion -
A.the speed of the people always increases, since now they have not one but two forces acting on them.
B.the speed of the car always increases, giving it greater force since the mass will remain the same.
C.the car now has a greater overall mass - its own mass plus the mass of the object by which it has been struck.
D.the people in the car will continue to move in the same direction and at the same speed as before the impact.
Answer:
D :)
Explanation:
When an impact causes the car to suddenly change its motion, (D) the people in the car will continue to move in the same direction and at the same speed as before the impact.
What is Newton's first law of motion?
Newton's first law of motion states that Unless influenced by an imbalanced force, a body at rest stays at rest, and a body in motion keeps moving in a straight path at a constant pace. This law is commonly known as law of inertia and the resistance of a body to maintain its state of rest is called inertia of rest, same as, the resistance of a body to maintain its state of motion is called inertia of motion.
When a car is moving with certain speed, the car along with the people inside the car is in inertia of motion. In an event of accident, the car comes in rest in no time but the man in the car is still in inertia of motion. So, his body moves forward in the car which may cause injuries. To prevent such injuries, the people inside a car are advised to use safety belts.
So, correct answer is option (D).

Write a hypothesis based on observations and scientific principles.
Answer:
An example of a hypothesis based on observation and scientific principles is:
Deaf children whose parents are deaf will acquire language faster than deaf children whose parents are not deaf.
A hypothesis is an informed prediction or a tentative statement about what you think that would occur in a scientific experiment as a result of experience from observations accepted by scientific rules and law.
A hypothesis is a testable statement obtained from the research question but questions cannot be tested directly, it is the proposed relationship between the variables that are tested.
An example of a hypothesis is:
Deaf children whose parents are deaf will acquire language faster than deaf children whose parents are not deaf.
This specifies the direction of the hypothesis because one group is faster than the other.

One long wire carries current 30.0 A to the left along the x axis. A second long wire carries current 50.0 A to the right along the line (y = 0.280m, z = 0). (c) What If? A uniform electric field is applied to allow this particle to pass through this region unelected. Calculate the required vector electric field.
The vector electric field is [tex]-1.73 \times 10^{4} {~}\hat{j} {~}N/C[/tex] .
A stream of charged particles, such as electrons or ions, flowing through an electrical conductor or a vacuum is known as an electric current.
One long wire carries a current I = 30.0 A to the left along the x-axis. I' = 50.0 A of current is being carried by a second lengthy wire to the right along the line (y = 0.280 m, z = 0).
Now,
The charge of a particle is q = - 2.00 μC which is moving with a velocity of [tex]v = 150\hat{i} {~}Mm/s[/tex].
At y = 0.1 m the total magnetic field is:
B = 1.16 × 10⁻⁴ T
Then the force on the particle is:
F =q(v × B)
[tex]F = (-2 \times 10^{-6} )[ ( 150 \times 10^{6})\hat{j} \times (1.16 \times 10^{-4})\hat{k} ][/tex]
F = 3.47 × 10⁻² N
A uniform electric field is applied.
Then the vector electric field will be:
F = qE
3.47 × 10⁻² = (-2 × 10⁻⁶ )E
[tex]E = -1.73 \times 10^{4}{~}\hat{j} {~}N/C[/tex]

In a diffraction experiment, a laser beam incident on a single slit of width a = 0.02
mm produces a diffraction pattern on a screen 100 cm from the slit. The width of the
central maximum is 2.8 cm. What is the wavelength of the light?
The n-th place is 2×10 −4 m
The diffraction pattern's minima is
nDλ =(3−1) d
Dλ = d
2Dλ
d= x 3 −x
2Dλ = 3×10 −3
2×0.50×6000×10 −10
=2×10 −4 m
Why do diffraction patterns occur?Diffraction of light, as it is used to describe light, occurs more explicitly when a light wave passes by a corner or via an aperture or slit that is physically
Light is diffracted primarily as a function of wavelength (frequency), amplitude, and slit width. The incident waves must have a larger amplitude than the slit width for any diffraction to take place. Diffraction won't happen if the wave is less than the slit width.
The quantity of diffraction increases with the wave's wavelength. When the gap size is almost equal to the wavelength, the most 2×10 −4 m occurs.

explain how electric motors convert electrical energy to mechanical energy
Answer:
[tex]\rightarrow[/tex] Electric motors build energy through the interaction between magnetic fields.
Magnetic fields may be generated by passing a current through a wire. Winding that wire into a coil intensifies the sector. Wrapping the coil around an iron core can intensify it more. One is going to be of the coil are North, the other South. Reverse the flow of current through the coil. The magnetic poles can swap. Place 2 separate coils close to one another and organize them therefore one turns whereas the opposite is fastened. Then build arrangements for this within the moving coil to reverse even as the opposite poles are about to line up.

a car initially traveling at 60 km/h accelerates at a constant rate of 2.0 m/s2. how much time is required for the car to reach a speed of 90 km/h? quizlet
Time required for the car to reach a speed of 90 km/h is 4.165 seconds.
To solve for time, use the formula for time, t = d/s which means time equals distance divided by speed.4.165 sec
In light of the posed query,
Initial velocity is 60 km/h, which is 60 x 1000 / 36600, or 16.67 m/s.
90 km/h is equal to 901000/3600, or 25.
2 m/s2 for acceleration, or a.
t = time
We are also asked to determine how long it will take the car to
accelerate to its final speed of 90 km/h.
We are aware,
v = u+at
Given the values we receive,
25 = 16.67 + 2t
2t = 25-16.67
2t = 8.33
t = 8.33/2
t = 4.165 sec
Thus, the car will take 4.165 sec to attain the final velocity of 90 km/h if its acceleration is 2 m/s^2 and initial velocity is of 60 km/h.
