Answer:
the ice became smaller and turned to liquid because of the absorption of heat from the surrounding of the ice cube which makes it to change its form from solid to liquid
Answer:
A. Electric potential energy into kinetic energy
Explanation:
The electric potential energy of the charged particles is converted into kinetic energy as the electron is released.
1: only half the outlet is switched and the lamp is in the other half
2: the lamp is turned off.
3: The light bulb is burned out
4: the switch might be broken
5: the fuse might be blown
6: the electricity might be off
That will depend on the coefficient of friction between the sliding surfaces, and also on Zak's weight. We don't have any of that information.
Answer:
The magnitude of Force is 8.58×10⁵N and direction is upwards
Explanation:
The work beam does on the pile driver is given by
W=(FCos180°)Δx= -F(0.088m)
From work energy theorem

Choosing y=0 at the the level where the driver first contacts the beam and vi=0 at yi=+3.40m and comes to rest again vf=0 at yf= -0.088m
So

The magnitude of Force is 8.58×10⁵N and direction is upwards
