The rock hits the water, it makes a sound and causes ripples on the surface of the water Student 2 observes the rock hitting the water.

Describe how the students could determine the speed of sound.

Avalue that describes how heavy an object is and is related to the force of gravity is

Debbie places two shopping carts in a cart corral she pushes the first cart which then pushes a second cart what force is being exerted

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
