To calculate the velocity relative to car A, you have to add the opposite of the velocity of car A to car B.

the velocity of car B relative to car A:
(let east and north directions be positive)
v = v (car B) - v(car A)
v(east-west direction) = -120 * cos 30° - 110
v(north - south direction) = -120 * sin 30° - 0

Find the time it takes for each object to accelerate from 0m/s to 40 m/s when pushed with 100N of force
Ivan

Answer:

40s

Explanation:

Given:

F=100N

V=40m/s and 0

force=change in momenton

F=mv-mu

t=40(100-0)/100

t=40/1

t=40s

A parallel plate capacitor stores charge, and thus, stores energy in the form of electric potential energy. The total energy sto
DIA [1.3K]

Answer:

The charges on the plates,

Explanation:

A capacitor is an electronic device that can be used for storing of charges. A parallel plate capacitor consists of two plates of equal area separated by a dielectric constant. The energy stored in the capacitor is in the form of potential energy which comes into play during the discharging process of the capacitor.

The energy stored depends majorly on the voltage, area of the plates, distance between the plates and the nature of the dielectric constant of the material between the plates. But it does not depend on the charges on the plates.
