Umm the rocks warm up until it becomes a not rock anymore and becomes really hot then it get so hot it starts coming out of a mountain called a volcanoe
Given that,
Radius of track, r = 50 m
time , t = 9 s
velocity, v = ?
Distance covered by car in one lap around a track is equal to the circumference of the track.
C = 2 π r = 2 * 3.14 * 50
C = 314.159 m
Distance covered by car, s = 314.159 m
Velocity = distance/ time
V = 314.159 / 9
V = 34.9 m/s
The average velocity of car is 34.9 m/s.
<span>The correct answer is b. An earthquake occurs. Basically, the earth's crust can't deal with the stress and strain so an earthquake occurs. That's why earthquakes are common where tectonic plates are unstable like the pacific area and the Western part of US. Places like Japan and San Francisco are famous for having earthquakes.</span>
