Forces that cause a change in motion of an object are

The correct answer is "unbalanced forces".

Explanation:

Balanced forces are two equal forces that act in opposite directions in the same object, resulting in the object being apparently static. On the other hand, unbalanced forces cause a change in motion because the forces that act on it are not equal in size or direction. The force that results from the two forces is known as the resultant force and is the one that provokes the motion of the object.

it is prolly d and c and f

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
