Jain applies a input force of 100 N to a lever that has a Mechanical advantage of

Output force = 300 N

Explanation:

Given that,

The mechanical advantage of a lever, m = 3

Input force,

We need to find the output force. The ratio of output force to the input force is called the mechanical advantage of the lever. So,

So, the output force is 300 N.

Savanna. Savanna is grassland with scattered individual trees. Savannas of one sort or another cover almost half the surface of Africa (about five million square miles, generally central Africa) and large areas of Australia, South America, and India. Climate is the most important factor in creating a savanna.
