Amy and ellie left school at the same time amy lives farther away then ellie but she and ellie arrived at theure homes at the same time compare the girls speed

Army and Ellie left school at the same time.

Army lives farther than Ellie.

They arrived at their homes at the same time.

This means that Army travels faster than Ellie.

Time

Since the time is constant here, increasing the distance directly increases the speed.

Ike is at the beach watching the waves in the ocean. Ike notices that some of the waves are short. Other waves are very tall and come up high above the water. Two waves that are different heights because They have different amplitudes.

Option (D) is correct

Explanation:

The different heights of the waves are due to their different amplitudes. The Amplitude of a particular wave depends upon the amount of energy being carried by waves. It the waves carry more energy than their amplitude will be higher.

But if energy carried by a wave is less than the wave will have a low amplitude. The Amplitude shows the distance covered from the rest position to peak position.
