How long will it take for an object to hit the ground when dropped from a height of 7m?

Answers

Answer 1

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.

what do you think a divergent (constructive) boundary is? How do plates interact with each other?

Answers

Divergent boundaries are areas where plates move away from each other, forming either mid-oceanic ridges or rift valleys. These are also known as constructive boundaries. ... This causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction.

Hope this helps.

The three ways waves change direction are reflection, refraction, diffraction.

In 3-5 complete sentences, compare those three ways that waves change direction.

Answers

Reflection is a change in direction of a wave between two different objects that is the Wave returns to the medium from which it begins.
Refraction is When a light travels from air into water it slows down causing it to change direction slightly.

Diffraction Involves a change in direction of waves as they pass-through and opening.

Reflection is a change in direction of a wave between 2 different objects that is the wave returns to the medium from which it begins.
Refraction is when a light travels from air into the water it slows down causing it to change direction slightly.

In 3-5 complete sentences, compare the three ways that waves change direction.

Answers

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.

i tried my best to help!

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
