The work done to lift the box is equal to the force applied multiplied by the distance moved, which is 20 joules in this case (10 N * 2 m). Power is the rate at which work is done, so if the box is lifted in 1 second, the power required would be 20 watts (20 joules / 1 second).
The work done to lift the log can be calculated using the formula: Work = Force x Distance. In this case, the force is 5000 N and the distance is 5 meters. Therefore, the work required to lift the log 5 meters would be 5000 N x 5 m = 25000 Joules.
The work done by a crane to lift a 1 kg car 10 meters would be 98.1 Joules. This is calculated as the product of the force required to lift the car (9.81 N/kg) and the distance the car is lifted (10 meters).
The work done to lift the petrified log 5 meters can be calculated using the formula: work = force × distance. In this case, the work required would be 25,000 joules (5000 N × 5 meters).
The minimum energy required to lift an object is equal to the work done, which is given by the formula: work = force x distance. In this case, the work done would be 200 N (force) x 20 m (distance) = 4000 joules. Therefore, the minimum energy required to lift the object weighing 200 N to a height of 20 meters is 4000 joules.
You could halve the effort required by moving the load closer to the fulcrum. Placing the load 0.5 meters from the fulcrum would reduce the effort needed to lift it. This is based on the principle of a lever, where the effort needed is inversely proportional to the distance of the load from the fulcrum.
The work done to lift the log can be calculated using the formula: Work = Force x Distance. In this case, the force is 5000 N and the distance is 5 meters. Therefore, the work required to lift the log 5 meters would be 5000 N x 5 m = 25000 Joules.

The work done to lift the petrified log 5 meters can be calculated using the formula: work = force × distance. In this case, the work required would be 25,000 joules (5000 N × 5 meters).
If it takes 3400J to lift a rock onto a ledge, what power is required to lift the rock onto the ledge in 4 seconds Power is energy per unit time. It is measured in watts (joules per second). As such if 3400 joules is transfeered in 4 seconds, the power equals 3400 / 4. The power required is therefore 850 watts.
The minimum energy required to lift an object is equal to the work done, which is given by the formula: work = force x distance. In this case, the work done would be 200 N (force) x 20 m (distance) = 4000 joules. Therefore, the minimum energy required to lift the object weighing 200 N to a height of 20 meters is 4000 joules.
I believe it is approximately 1.13 cubic meters (1.13 litres will lift 1 gram; do the math.
You could halve the effort required by moving the load closer to the fulcrum. Placing the load 0.5 meters from the fulcrum would reduce the effort needed to lift it. This is based on the principle of a lever, where the effort needed is inversely proportional to the distance of the load from the fulcrum.
The height is irrelevant. The energy required depends on the height; the force does not. The weight of an object, and therefore the force required to lift it, is mass x gravity - about 500 Newtons.The height is irrelevant. The energy required depends on the height; the force does not.

To calculate the work done when lifting an object, you can use the formula: work = force × distance. The force required to lift an object is equal to its weight, which is mass × gravity. So, you would need to know the mass of the object to calculate the work done when lifting it 1600 meters.
Please use the formula for gravitational potential energy (PE = mgh) to calculate the energy required. Then divide that by the time to get the power.
Work = force x distance = (4 x 10) = 40 newton-meters = 40 joules
The electrical power required for a lift (elevator) can be calculated using the formula: Power (P) = Work done (W) / Time (t). The work done is determined by the weight of the load multiplied by the height it is lifted (W = weight × height). For a more precise calculation, factors such as efficiency, friction, and speed of the lift should also be considered, as they can impact the total power requirement.
