Which of the following is the best example of Newton's second law? A. A rolling ball comes to a stop because the forces of frict
ion and gravity are acting upon it. B. The acceleration of a skydiver depends upon the force of gravity and wind resistance. C. As a boat propeller forces water in one direction, the boat moves in the opposite direction. D. When a basketball strikes the ground, the ground exerts an upward force on the basketball.
B. the acceleration of a skydiver depends upon the force of gravity and wind resistance
Explanation:
Newtons second law of motion states that: the force (F) acting upon an object is directly proportional to the mass (M) of the object and the acceleration (a).
Basically this law states that the acceleration of a body is dependent on the force and mass of the body. If the force exerted on the body changes the acceleration will also change. and if the mass of the body changes, the acceleration will also be affected
from the options, the only option that refers to acceleration is option B
I think the correct answer would be that the temperature of the clouds that made the very first stars where thought to be higher since the clouds are made up of hydrogen and helium. Hope this answers the question. Have a nice day.
Entropy is typically defined as either the level of randomness (or disorder) of a system or a measure of the energy dispersal of the molecules in the system.
