Answer:
Multiply the time by the acceleration due to gravity to find the velocity when the object hits the ground. If it takes 9.9 seconds for the object to hit the ground, its velocity is (1.01 s)*(9.8 m/s^2), or 9.9 m/s.

In 3-5 complete sentences, compare the three ways that waves change direction.
Answer:
There are many ways to compare waves and how they change direction. The most common way is through the wind. This is different from human force because of direct contact in the wind and human force. However they both intact something physically moving the ocean. This compares how different waves move.

Answer:
Reflection is the change in direction of a wave between two different objects such that the wave returns to the medium from which it began. In other words, the waves are sent back towards the source. Sound waves, light waves, and water waves can all be reflected.
Explanation:
Incident Ray – the wave/ray traveling towards a surface
Angle of Incidence – the angle at which the traveling wave/ra
y hits a surface
Equal (or Normal) – divides the two rays (incident / reflected) into two equal angles
Angle of Reflection – the angle at which the reflected wave returns towards the original medium
Reflected Ray – the wave/traveling away from the “hit” surface, and now traveling towards the original medium
