Which of the following situations demonstrates balanced forces? a. a child on a moving seesaw b. a car driving on a straight freeway at 60 miles per hour c. a clock's pendulum in motion d. a rock thrown upward, being acted on by gravity

option B. a car driving on a straight freeway at 60 miles.

Explanation:

A balance forces are said to act on an object when net force on an object is zero and the object is either at rest or moves with constant speed without changing direction.

In option A, C, and D the objects are changing direction during their motion. In option B, a car moves on a straight freeway in a single direction at constant speed of 60 miles per hour. Hence, the correct demonstration of balanced forces is by option B.

the answer is the car on the highway of your doing study island

temp rises, and expansion

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
