What is the ima of the lever pictured?

0.18
0.20
0.90
5

Option B: 0.20

An ideal machine is where there is not friction or the same amount of effort put on the machine is wasted to overcome friction. IMA stands for Ideal Mechanical Advantage. For a lever system, it can be calculated using the following formula:

Here, resistance distance corresponds to the length of the whole ramp,

Thus, resistance distance is 1.5 m

And the effort distance is 0.3 m

On putting the values in the fromula:

Therefore, IMA for the liver system is 0.20.

- decrease the number of plants and animals living in the water.
