Answer:

The atmospheric pressure goes on decreasing as we go up above the sea-level. Therefore, the amount of oxygen also decreases at higher altitude. Due to this reason, mountaineers carry oxygen cylinders with them, while climbing high mountains

Dr. smith has just been appointed chief of staff at a large hospital located near an area of town where many minorities live. dr

Trava [24]

In such a situation it would be best if Dr. Smith:

<span>''hire trained therapists who are from the same minority group''

This would have a wide ranging impact on the minority communities in the area.

Their participation would increase rapidly as their own community members would get the word out on the services provided and they might feel more comfortable in such an environment.

Since, mental health still has a stigma attached to it, especially in immigrant communities, this strategy would help to increase the level of mental health services provided to minority groups.

The gravitational potential energy of Sara at the given height is 10594.8J.

Given the data in the question;

Mass of Sara; $m; = 60kg$

Distance from ground; $h = 18m$

Acceleration due to gravity; $g = 9.81m/s^2$

Gravitational potential energy; $U = \ ?$

<h3>Gravitational Potential Energy</h3>

Gravitational potential energy is the potential energy an object with mass posessses relative to another object with mass due to gravity.

It is expressed as;

$U = mgh$

Where m is mass, h is height and g is acceleration due to gravity.

To determine the gravitational potential energy of Sara, we substitute our given values into the expression above.

$U = mgh\\\\U = 60kg * 9.81m/s^2 * 18m\\\\U = 10594.8kgm^2/s^2\\\\U = 10594.8J$

Therefore, the gravitational potential energy of Sara at the given height is 10594.8J.
