Answer: What happens when the thermal energy of a substance increases is that D. Both the motion of the particles in the substance and the temperature of the substance increase.
Explanation: When thermal energy increases, it is due to particles moving faster. It also results in higher temperatures or heat.
In order to find the displacement of something, you can calculate it by subtracting the initial distance from the final distance.
7-5 =2
so the mouse would’ve walked a displacement of 2cm

The equatorial radius of the earth is
r = 6378 km = 6378 x 10³ m
The earth makes 1 revolution in 24 hours.
The angular velocity is
ω = (2π rad)/(24*3600 s) = 7.2722 x 10⁻⁵ rad/s
The tangential velocity (linear velocity) at a point on the equator is
v = rω
= (6378 x 10³ m)*(7.2722 x 10⁻⁵ rad/s)
= 463.8 m/s
Answer: 463.8 m/s
