∙ 11y agoWork done equals force times distance, so 10.0 times 0.9 is 9 joules.

∙ 11y agoThe work done can be calculated using the formula: work = force x distance. Plugging in the values, work = 10.0 N x 0.9 m = 9.0 Joules. Therefore, you would do 9.0 Joules of work to lift the box.

You would do 7.5 Joules of work. Work is calculated by multiplying force by distance displaced in the direction of the force. In this case, 10.0N * 0.75m = 7.5J.
The torque you exert on the door is calculated by multiplying the force applied by the distance from the hinges. In this case, the torque exerted is 30 N * 0.85 m= 25.5 Nm.
The amount of work done to lift an object is equal to the force applied multiplied by the distance over which the force is applied. Without information about the force or mechanism used to lift the beam, it is not possible to calculate the work done.
Using a fixed pulley system, you would still need to exert the same amount of force as the weight you are trying to lift. So, to lift a 300 kg weight, you would need to exert a force equal to the weight (300 kg) times the acceleration due to gravity (9.81 m/s^2), which equals 2943 N.
The work done to lift the box is given by the formula: work = force x distance. Plugging in the values with force = 10.0 N and distance = 0.9 m, the work done would be 9.0 Joules.

The answer would depend on the units used for the force. Since these are not specified, it is not possible to answer the question.
Because it's five times heavier of course !

No matter how much force you exert downward, it shall avail you naught. No downward force acting directly on the object can ever succeed in lifting it.
Using a fixed pulley system, you would still need to exert the same amount of force as the weight you are trying to lift. So, to lift a 300 kg weight, you would need to exert a force equal to the weight (300 kg) times the acceleration due to gravity (9.81 m/s^2), which equals 2943 N.
The work done to lift the box is given by the formula: work = force x distance. Plugging in the values with force = 10.0 N and distance = 0.9 m, the work done would be 9.0 Joules.
Work = Force X Distance 20 N X 10 m = 200 N-m
All objects with mass exert gravitational force. This means that everything in the universe, no matter how large or small, pulls on everything else with a force that depends on their masses and the distance between them.
