Answer:

The answer is d. water molecules near the surface produce more buoyant force than water molecules within the liquid

Explanation: Surface tension is defined as the attraction on the water of like particles to one another. Water molecules on a surface undergoes cohesion or the sticking together of one molecule to another of the same material.

Answer:

D)Water molecules near the surface produce more buoyant force than water molecules within the liquid.

Explanation:

Buoyant force that is provided by water molecules such that the object can float on the surface of the water. According to Archimedes principle for flotation to occur the buoyant force must be equal to the weight of the object. If the buoyant force is less than the weight of the object, then the object will sink.

nexus9112 [7]

Answer: Friction.

Explanation: Even though the driver has taken the foot off thr gas pedal, the acceleration of the car decreases and the friction continues.

The car slows down because the opposite force of friction continues to act and the acceleration in forward direction is continuous decreasing. Hence, the car slows down.

How does energy change form when friction causes the temperature of an object to increase?

Oksanka [162]

I believe the answer would be through the movement of the molecules, the higher the temperature the more the molecules move around and vibrate.
