The speed for a curve of a given radius is proportional to the square root of the coefficient of static friction. The allowed speed in the second curve is about
(20 m/s)√(0.7/1.1) ≈ 15.95 m/s
Answer:
Friction can stop or slow down the motion of an object.
Explanation:
The slowing force of friction always acts in the direction opposite to the force causing the motion.
A jet stream forms high in the upper troposphere between two air masses of very different temperature. The greater the temperature difference between the air masses, the faster the wind blows in the jet stream.
.
.
So "Differences in temperature between two air masses" is the answer
Thermonuclear fusion is when matter is heated to a high degree
