To find work, you use the equation: W = Force X Distance X Cos (0 degrees)
Following the Law of Conservation of Energy, energy cannot be destroyed nor created.

So you would do 75 N x 10m x Cos (0 degrees)= 750 J

Answer:

The work done by Lee is 3528 Joules.

Explanation:

Given that,

Mass of the object, m = 36 kg

Force applied by Lee on the object, F = 75 N

The object moves to a distance, d = 10 m

We need to find the amount of work done by Lee. It is given by the combination of force and displacement of an object. It is given by :

W=F{\cdot} d

W=mg{\cdot} d

W=36\times 9.8\times 10

W = 3528 Joules

So, the work done by Lee is 3528 Joules. Hence, this is the required solution.

Why is radiation fog more likely near the center of an anticyclone than near the center of a cyclone?
Zigmanuir [339]
Radiation fog is the fog that is formed when the heat absorbed the Earth's surface is released into the atmosphere producing fog. This only occurs when the air is clear and calm. In the center of an anticyclone, the conditions of the air are clear and calm which is favorable for the formation of radiation fog. The center of cyclones, on the other hand, is turbulent and cloudy which prevents the formation of radiation fogs.

Mrac [35]

Answer:

It is the ratio of the density of a substance to the density of a given reference material.

Explanation:

<em>Specific gravity is also known as relative density.</em>

<u>To find the relative density of substance, you:</u>

  • Divide the density of substance measured
  • And divide that by the density of the reference
