A force of 20 newtons acting through a distance of 40 meters produceswork equal to (20 x 40) = 800 newton-meters = 800 joules.The weight of the cart doesn't matter.
The effort force required to lift a 10kg load would be equal to the weight of the load, which is 10kg multiplied by the gravitational acceleration, which is approximately 9.81 m/s^2. So, the effort force would be approximately 98.1 Newtons.
Using a single fixed pulley will not change the amount of effort needed to lift a load. You will need to exert a force equal to the weight of the load, in this case 10 newtons, to lift it. The fixed pulley only changes the direction of the force needed, not the amount of force required.
If the effort force for a lever is 50 Newtons and there is no friction, then the resistance force would also be 50 Newtons in an ideal situation with a first-class lever and IMAAMA. This is because in this case, the input force (effort force) is equal to the output force (resistance force) due to the principle of moments.
In a movable pulley system, the effort force required would be equal to half the weight being lifted. So to lift a 300 kg weight, you would need to apply an effort force of 150 kg (approximately 1471 Newtons) assuming ideal conditions and neglecting friction and other losses.
Newtons! :)

It rotates freely until it is required to do work. As soon as a load is placed across the output more effort will be required to rotate the Dynamo.
The allusion to Herculean effort refers to an exceptionally great and difficult task or undertaking. It originates from the myth of Hercules, who performed twelve extraordinary labors that required immense strength, skill, and determination. When someone mentions a Herculean effort, they are highlighting the monumental nature of the challenge being faced.
In a movable pulley system, the effort force required would be equal to half the weight being lifted. So to lift a 300 kg weight, you would need to apply an effort force of 150 kg (approximately 1471 Newtons) assuming ideal conditions and neglecting friction and other losses.
The mechanical advantage (MA) of a machine can be calculated using the formula: MA = Load Force / Effort Force. In this case, the load force is 1700 newtons and the effort force is 340 newtons. Therefore, MA = 1700 N / 340 N = 5. This means that the pulley system provides a mechanical advantage of 5, allowing a smaller force to lift a heavier load.
The effort required for zero load is minimal as there is no external force or resistance to overcome. It typically involves low to no exertion or energy expenditure.
No. Are you serious? Think about the number of cars coming across the border and the amount of time and effort required to do so. I've personally traveled across the border a number of times and have never been searched.
