Part a

find the energy u0 stored in the capacitor. express your answer in terms of a, d, v, and ϵ0. remember to enter ϵ0 as epsilon_0.

part b

the capacitor is now disconnected from the battery, and the plates of the capacitor are then slowly pulled apart until the separation reaches 3d. find the new energy u1 of the capacitor after this process.

express your answer in terms of a, d, v, and ϵ0.

part c

the capacitor is now reconnected to the battery, and the plate separation is restored to d. a dielectric plate is slowly moved into the capacitor until the entire space between the plates is filled. find the energy u2 of the dielectric-filled capacitor. the capacitor remains connected to the battery. the dielectric constant is k.

express your answer in terms of a, d, v, k, and ϵ0.

gravititional force is a force that is acting around you, it is non-contactable and it is a force that pulls you to the core of the earth.

anchor = archer //

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
