Answer:
4.408 m.
Explanation:
Given:
m = 72.1 kg
vf = 9.3 m/s
vi = 0m/s
a = 9.81 m/s^2
Equations of motion:
i. vf = vi + a*t
ii. S = vi*t + 1/2*(a*(t^2))
iii. vf^2 = vi^2 + 2a*S
Using iii. equation of motion;
(9.3)^2 = 0 + 2 * (9.8) * S
S = 86.49/19.62
= 4.408 m.
Answer:
"The idea behind thermal expansion is that gases expand as the temperature increases. If you have a balloon and you heat up the contents, the balloon will get larger. Scientists use the term ideal gas law to describe this activity. Liquids expand and contract, too, but there is a lot less change than in gases."
I don't know if this is what u meant, but, hope this helps :3

Any matter that is a solid has a definiteshape and a definite volume. The molecules in a solid are in fixedpositions and are close together. Although the molecules can still vibrate, they cannot move from one part of the solid to another part. As a result, a solid does not easily change its shape or its volume.
The block will float because the density of the wood is less than the water.
