Select the correct answer.
why does a solid change to liquid when heat is added?
a. the spacing between particles decreases.

b. particles lose energy

c. the spacing between particles increases.

d. the temperature decreases.

The spacing between the particles decreases and also loses energy

Explanation:

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
