hope it helps
Answer:
Answer C : person on an elevator going down
Explanation:
We look for a change in state of motion in order to have a net force different from zero in the system. The state of motion doesn't change in any of the examples a, b, or d. But there is a change in the state of motion in case c where initially the person and elevator where in static equilibrium, and later the elevator started going down and accelerating from zero speed to another non zero speed.
B) compound.
A compound is usually made up of different Elements, a compound is likely to have a melting point as well.
Answer:
3rd choice
Explanation:
heat is transfered causing it to melt
Answer:
<h2>4.9 J</h2>
Explanation:
The gravitational potential energy of a body can be found by using the formula
GPE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
GPE = 10 × 9.8 × 0.05
We have the final answer as
<h3>4.9 J</h3>
Hope this helps you
