How much work is done when an object with a mass of 78 kilograms is lifted through a height of 6 meters?
78*6*9.8 N = 4586.4 N
A 10 KG mass is lifted to a height of meters what is its weight?
To get the weight (in Newton), multiply the mass by Earth's gravitation - about 9.8, in SI units.
How much work is done if the mass 3.0kg lifted 40 meters?
work is equal to a change in energy. in this case there is a change in potential energy. potential energy = mass x gravity x height E(p)=mgh E(p)= 3x9.8x40 E(p)=1176 J thus there is a change in potential energy of 1176 joules and since W=change E(p) Work done is 1176 J
What is the mass of a person weighing 200 newtons?

What is the device comparing the mass of an object to a known mass?
The device used for comparing the mass of an object to a known mass is a double pan balance, or a balance scale. This is a type of weighing scale where you put weights on one pan and the substance you are weighing on the other.
How much work is done when an object with a mass of 78 kilograms is lifted through a height of 6 meters?
78*6*9.8 N = 4586.4 N
How would you measure the mass of 92 oranges with a mass of 6.41?
Usually this would be done by weighing them.
An object with a mass of 21kilograms is lifted through a distance of 7 meters How much work is done?
use the formula W = mgs W stands for work done in joules m stands for mass of the object g stands for gravity s stands for the distance the object is lifted W = mgs W = 78kilograms•9.8m/s2•6meters W = 4586.4 J (joules) answer would be 4,586.4 J
How many joules of work are done when a 200 kg box is lifted 5 meters above the floor?
The work done is equal to the change in potential energy, which can be calculated as (mass x gravity x height). Plugging in the values: (200 kg x 9.8 m/s^2 x 5 m) = 9800 J. Therefore, 9800 joules of work are done when the box is lifted 5 meters above the floor.
A 10 KG mass is lifted to a height of meters what is its weight?
To get the weight (in Newton), multiply the mass by Earth's gravitation - about 9.8, in SI units.
An object of mass 4.5 is lifted through a distance of 10m H ow much work is done?
The work done is given by the formula: work = force x distance. Since the force required to lift an object against gravity is equal to its weight (mass x gravity), the work done is 4.5 kg x 9.8 m/s^2 x 10 m = 441 J.
An object with a mass of 21 kilograms is lifted through a distance of 7 meters How much?
question 24 on penn foster is C.
How many joules of work are needed to life a 15 kilogram mass 3 meters off the ground?
The work done to lift the 15 kg mass is 441 J. This can be calculated by multiplying the weight of the object (15 kg * 9.8 m/s^2) by the height lifted (3 m).
How much work will it take to lift a 6kg toolbox 1.5 meters onto a shelf in the garage?
The work done to lift the toolbox is calculated as the force (weight of toolbox) multiplied by the distance it moves (height lifted). In this case, the work done will be 6kg (mass of toolbox) * 9.81 m/s^2 (acceleration due to gravity) * 1.5m (height lifted), which equals 88.29 Joules.
How do you find a total mass of something?
This is usually done by weighing. On Earth, mass and weight are proportional; in fact, balances are usually calibrated for mass units, even if some of them really determine the weight.
How much work is done when a 1-kg mass is raised a vertical distance of 1 m?
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.
How do you find mass of one cubic meter of something?
The relationship is: density = mass / volume. Solving for mass: mass = density x volume. So, if you know the density, you can do the multiplication. Otherwise, you will have to measure the mass - this is usually done by weighing.
