Arock is dropped from a bridge. what happens to the magnitude of the acceleration and the speed of the rock as it falls? a) both acceleration and speed increase b) both acceleration and speed remain the same c) acceleration increases & speed decreases d) acceleration remains the same & speed increases

The acceleration of the rock remains the same while the speed increases as the rock moves downwards.

The motion of an object dropped from a certain height is affected by Earth's gravitational influence.

The object's speed increases as the object moves downwards and it will eventually become maximum before the object hits the ground.

Thus, we can conclude that the acceleration of the rock remains the same while the speed increases as the rock moves downwards.

If a rock is dropped from a bridge, its acceleration remains the same (9.8 m/s², the acceleration of gravity on Earth, no matter how heavy the rock is), and its speed increases at the rate of (9.8 meters per second for every second it falls).

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
