Answer:
e) J
Explanation:
= Magnitude of electric field = 5 V/m
= Area of window = 1.5 m²
= speed of electromagnetic wave = 3 x 10⁸ m/s
= time interval = 1 h = 3600 sec
radiation energy is given as
J
Let be the distance between the base of the ladder and the bottom of the wall, and the distance between the top of the ladder and the bottom of the wall, so that
Differentiate both sides with respect to time :
When , the top of the ladder is
above the ground. Then, given that the bottom of the ladder slides away from the wall at a rate of , we have
That is, the top of the ladder is sliding downward at a rate of 0.24 ft/s.

Answer:
The amount of water it displaces (shaded area ) weighs as much as the ship. The weight of the ship pulling down and the upthrust pushing up are equal and opposite forcers so the ship floats.
Explanation:
Now the weight of the ship is more than the maximum possible upthrust so it sinks to the buttom
