Suppose the electric Entensity between two parallel plates, placed 1cm apart
is 10⁴NC^-1 and the direction of the field of this intensity is vertically upward. find the force on an electron in this field and compare with the weight of the electron​

Why don't you see your reflection in water with waves or repples

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.

Amother used 150 watts of power to raise a 15 newton object in a time interval of 8.0 seconds. through what vertical distance was the object raised ?
