Answer:
a box moving along a conveyor belt possesses kinetic energy.
Lightning produced during a storm gives electrical energy.
a piece of fruit hanging from a tree possesses gravitational potential energy.
Sand on a beach feel warm to touch because the sand possesses thermal energy.
Radio waves transmitted from a tower (radiant energy).
Explanation:
If it starts at rest the initial velocity is 0.
For an acceleration, a, and time, t, the velocity is v=at. Since at t=4, v=7, then a=7/4=1.75m/s^2
Total distance between Sally's house and mall = 10 kilometers
Distance covered during half way drive = Kilometers
Now, she goes back to her home.
Distance covered going back home = Kilometers
Now, she drives from home to mall.
Distance covered from Sally's home to mall = 10 kilometers
Hence, the total distance Sally traveled = 5 + 5 + 10
Total distance Sally traveled = 20 kilometers
Hence, the answer is 20 kilometers
Answer:
Force will be
Explanation:
We have given side of wire d = 2.3 cm = 0.023 m
Magnetic field B = 1.5 T
Velocity v = 2.1 m/sec
Resistance R = 3 ohm
We know that current is given by
Power is given by
We know that power is also given by
So
