The work done when lifting a 10 kg mass up a distance of 20 m can be calculated using the formula: work = force x distance. In this case, the force exerted is equal to the weight of the mass, which is given by the formula: weight = mass x gravity. Using a standard gravity value of 9.81 m/s^2, the weight of the mass is 10 kg x 9.81 m/s^2 = 98.1 N. Therefore, the work done is 98.1 N x 20 m = 1962 Joules.
With extreme difficultly as they measure different things: mass is a measure of how much something weighs*, whereas length is a measure of distance. * Actually weight is the force on a mass due to acceleration and is measured in Newtons. However, weight and mass are often, incorrectly, used interchangeably and I cannot think of a better word to describe mass. To further muddy the waters, mass and distance ARE related by energy and acceleration: energy = (mass × acceleration) × distance which can be rearranged to distance = energy ÷ (mass × acceleration) So for an object given a mass, an acceleration (on earth acceleration due to gravity is a good one) and an amount of energy put in, the distance the object is moved (by that energy [in acting as a force]) can be calculated.

Weight of a mass of 50 kg = [ m g ] = (50 x 9.8) = 490 newtons.Work = force x distance = 490 x 4 = 1,960 newton meters = 1,960 joules
The two factors are the amount of mass an object has and the distance between the two objects.
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.
The amount of work done in lifting a block is equal to the force applied multiplied by the distance over which the force is applied (W = F*d). If you provide the force applied, I can calculate the work done.
The work done in lifting a 60kg crate a vertical distance of 10 meters is given by the formula: work = force x distance x cos(theta), where force = weight x gravitational acceleration = 60kg x 9.8 m/s^2, distance = 10m, theta is the angle between the force and direction of displacement (which is 0 in this case, as it's lifting vertically). Plugging in the values, the work done is approximately 5,880 Joules.
The work done in lifting a 50kg object to a height of 5m is 2450 Joules, calculated using the formula: Work = force x distance x cos(theta).
The work done in lifting the refrigerator can be calculated by multiplying the force applied (700 N) by the distance traveled (4 meters). Therefore, the work done would be 700 N * 4 meters = 2800 joules.
The work done in lifting an object is given by the formula: work = force x distance. The force required to lift an object against gravity is equal to the weight of the object, which is mass x gravity. So, work = (20 kg x 10 m/s^2) x 0.40 m = 80 J.
The work done when lifting the tomato is equal to the force required to lift it multiplied by the distance it is lifted. The force can be calculated using the formula F = mg, where m is the mass of the tomato and g is the acceleration due to gravity. Once the force is calculated, multiply it by the distance lifted to get the work done.
The work done is 1 Joule. Work is calculated by multiplying force (1N) by the distance moved (1m) in the direction of the force.
The work done in lifting the fridge is equal to the force applied (700 N) multiplied by the distance moved (4 meters), which gives a total work of 2800 joules.
If you lift two loads up one story, you are doing twice the work compared to lifting just one load up one story. This is because work is directly proportional to the force you apply and the distance over which you apply it, so lifting two loads requires double the effort.
The work done is equal to the force needed to lift the mass multiplied by the vertical distance lifted. In this case, the work done is equal to the gravitational force acting on the mass (m x g) multiplied by the vertical distance lifted (1 m). So, the work done would be 1 kg * 9.8 m/s^2 * 1 m = 9.8 Joules.
The work done in lifting the sack of rice is given by the formula: work = force x distance. The force required to lift the sack is equal to the weight of the sack, which is 600kg x 9.81 m/s^2 (acceleration due to gravity). Therefore, the work done is 600kg x 9.81m/s^2 x 10m = 58,860 Joules.
