Hello. This question is incomplete. The full question is:

"Which statement best describes why a machine is useful?  A-A machine does a greater amount of work than the amount of work that is done on it.  B-A machine does a smaller amount of work than the amount of work that is done on it.  C-A machine can decrease both the input force and the input distance needed to do a given amount of work.  D-A machine can decrease either the input force or the input distance needed to do a given amount of work."

Answer:

D-A machine can decrease either the input force or the input distance needed to do a given amount of work.

Explanation:

A machine is a device that uses energy and work to achieve a predetermined goal. In Physics, any device that changes the direction or intensity of a force with the use of work. In summary, we can say that what best describes why a machine can decrease the input force or the input distance needed to perform a certain amount of work, for this reason, the machine is useful.

Read the passage about the pygmy shrew.
cestrela7 [59]

Answer:

<em>A very high metabolism and a very small size.</em>

<em></em>

Explanation:

The pygmy shrew is a very small mammal, that forages day and night. The metabolism of the Pygmy shrew is so high that it must eat at least every 30 minutes or it might die. The best explanation for what happens to the food's mass and energy is that most of the food mass is rapidly used fro building up of the shrew due to its very high metabolism, and a bigger portion of the food is lost from the surface of the body of the shrew, due to its very small size. The combination of these two factors; a very high metabolism (rapidly uses up food material, and generates a large amount of heat in a very short time) and the very small size (makes heat loss due to surface area to volume ratio high) explains what happens to the food mass and energy.

The velocity of S wave decreases as these waves leave the lithosphere and enter the asthenosphere. What does this suggest about
QveST [7]

The asthenosphere is thicker than the lithosphere, where the speed was faster.

<h3>Velocity of S wave</h3>

The velocity of s wave decreases as the thickness of the Earth layer increases, because it will take more time to travel through the given thicker formation.

The magnitude of velocity is given as;

v = x/t

where;

  • x is the thickness of the Earth layer
  • t is the time of motion

This implies that the speed of the s wave will high in thin formation and low in thick formation (layer).

When the velocity of S wave decreases as the waves leave the lithosphere and enter the asthenosphere, it implies that the asthenosphere is thicker than the lithosphere, where the speed was faster.
