Answer:
A
Explanation:
The acceleration of an object is directly proportional to its net force.
Answer:
a. mechanical; require a medium to travel through
Explanation:
Longitudinal, transverse and surface waves are types of mechanical waves. For example, within the longitudinal waves are the sound waves, which needs a medium to propagate like the air. This is why sound does not travel in a vacuum.
And an example of a transverse wave is the waves that form in the water when a rock is thrown (ripples), these waves need a medium (the water) to propagate.
On the other hand, electromagnetic waves such as light waves do not need a medium to propagate, this is why we can see the light of distant stars because their light travels through the vacuum until it reaches us.
So, the answer is:
Transverse, surface, and longitudinal waves are all mechanical waves because they require a medium to travel through .
The amplitude determines the volume of the sound. This isn't affected by the motion of the sound source.

Answer:
a fad diet is basically a diet that was a trend or that was popular for a short amount of time and makes unreasonable claims for fast and very much wanted results
Explanation:
<span>Wind power is produced from the
wind turbines or sails that uses air flow to convert it into mechanical power. It
is an alternative to fossil fuel burning, it is all around, renewable, clean,
produces no greenhouse gases and uses little land. The advantages of wind power
have been greatly praised by many. However, it has disadvantages. Wind power
especially at farm is noisy and may spoil the view for their neighboring people.
Also the amount of electricity depends on the strength of the wind. If no wind
is around, no electricity is produced. </span>
