A body start from rest and acceleration uniformly until it reach a velocity of 30m/s after five second. it travelled with a uniform velocity for 15s is then brought to rest in 10s with a uniform dation calculate​

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter

The field between two charged parallel plates is kept constant. if the two plates are brought closer together, the potential difference between the two plates either a) decrease b) does not change c) increase?

Atriangle with equal sides of length 10 cm has -2.5-nc charged objects at each corner. part a determine the direction of the electrical force exerted on the object at the top corner due to the two objects at the horizontal base of the triangle. determine the direction of the electrical force exerted on the object at the top corner due to the two objects at the horizontal base of the triangle. horizontally rightward vertically downward vertically upward horizontally leftward
