Answer:
Increase
Explanation:
The acceleration will increase more if all the friction were removed from ramp.
Acceleration is the rate of change of velocity with time.
Frictional force is a force that opposes motion of a body.
- A large friction will reduce the velocity of a body significantly and bring it to stop, a state of no acceleration.
- When friction is removed, the acceleration of a body will increase significantly since the velocity will change rapidly.
- At each turn of time, the velocity keeps increasing due to absence of the inhibiting force of friction.

Answer:
Explanation:
As we know that
E = 1.8 kV/mm
now we know that electric field between the plated of capacitor is given as
now we will have
now we have
now we have area of the plates of capacitor
Answer:
magnitude of the pressure on the sail in the vicinity of Earth’s Orbit=
Explanation:
The momentum of a photon is:
p = E/c
E = the photon energy
c = the speed of light.
take the time derivative (gives the force)
F = dp/dt = (dE/dt)/c
F = 2(dE/dt)/c (is doubled for complete reflection of the light)
Intensity has the units of energy per unit time per unit area
= I
then,
Force/unit area = 2I/c
magnitude of the pressure on the sail in the vicinity of Earth’s Orbit=
