To determine the efficiency of the machine, we need to use the formula:

Efficiency = (Output work / Input work) * 100%

The output work is the work done by the machine, which is equal to the product of the load and the distance it is moved:

Output work = Load * Distance

In this case, the load is 1.0 newtons and the distance is 1.6 meters, so the output work is:

Output work = 1.0 N * 1.6 m = 1.6 Nm

The input work is the work done by the effort, which is equal to the product of the effort and the distance it is moved:

Input work = Effort * Distance

In this case, the effort is 4.8 newtons and the distance is 0.35 meters, so the input work is:

Input work = 4.8 N * 0.35 m = 1.68 Nm

Now we can calculate the efficiency:

Efficiency = (Output work / Input work) * 100%

= (1.6 Nm / 1.68 Nm) * 100%

= 0.9524 * 100%

= 95.24%

Therefore, the efficiency of the machine is 95.24%.

Efficiency = (Output work / Input work) * 100%

The output work is the work done by the machine, which is equal to the product of the load and the distance it is moved:

Output work = Load * Distance

In this case, the load is 1.0 newtons and the distance is 1.6 meters, so the output work is:

Output work = 1.0 N * 1.6 m = 1.6 Nm

The input work is the work done by the effort, which is equal to the product of the effort and the distance it is moved:

Input work = Effort * Distance

In this case, the effort is 4.8 newtons and the distance is 0.35 meters, so the input work is:

Input work = 4.8 N * 0.35 m = 1.68 Nm

Now we can calculate the efficiency:

Efficiency = (Output work / Input work) * 100%

= (1.6 Nm / 1.68 Nm) * 100%

= 0.9524 * 100%

= 95.24%

Therefore, the efficiency of the machine is 95.24%.
