78*6*9.8 N = 4586.4 N

To get the weight (in Newton), multiply the mass by Earth's gravitation - about 9.8, in SI units.

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

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.

Usually this would be done by weighing them.

I believe that when you say 'lifted through', you mean lifted to a height of 10m. If so, the amount of work is such: Work= Force x Distance which have the units (Joules = Newtons x meters) When the object is lifted, it increases in its potential energy. The equation for this is: Potential energy = mass x gravitational force x height = 4.5 x 9.81 x 10 =441.45 Joules As 1 joule = 1 newton x meters and we have 441.45 Joules, 441.45 joules of works is done! :D

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

Work = (force) x (distance) = 7 x 2.4 = 16.8 joules

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.

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.

The weight is the mass multiplied by the acceleration of gravity. When weighing an object by a balance the acceleration of gravity is on both sides of weighing and hence canceling its effect and hence you get the object mass (not the weight)..

Basically by weighing it. Although mass is not the same as weight, if you know the weight and the gravity, you can calculate the mass.Basically by weighing it.
