Answer:
3cm should be the answer correct me if I'm wrong
Explanation:
Divide the input by the output
The ideal mechanical advantage of the hammer is the ratio of its input distance to the output distance . The ideal mechanical advantage of the hammer with input distance of 3 cm and output distance of 9 cm is 3 cm.
What is mechanical advantage?Mechanical advantage of an machine or an equipment is the measure that how much input force is changed to output. It is the ratio of output force to the input force. This ratio is the actual mechanical advantage of the machine.
The actual mechanical force also accounts for the frictional force also. The amount of input force needed to overcome the friction is considered here.
The ideal mechanical advantage the distance measurements are used since it is difficult to measure the input/output force.
given that, input distance = 9 cm
output distance = 3 cm.
ideal mechanical advantage = input distance/ output distance
= 9 /3 = 3 cm.
Therefore, the ideal mechanical advantage of the hammer is 3 cm.

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
