The amount of energy required is found by the following equation E=mgh
Energy=mass*gravity*height m=100Kg
g=9.81m/s^2 (Standard gravity on Earth)
h=1.00m
so,
E=(100)*(9.81)*(1.00)=981J The second is irrelevant when determining energy, it would take 981J to lift it in 1 second or in 1 year. However, power takes time into consideration as it is the rate at which work is performed, P=E/t
Power=energy/time
=981/1=981W 100 Joules I believe.

That depends how fast you want to do this. Please note that "watt" is not a unit of energy, it's a unit of power (energy per time unit).
For a physical meaning, take potential energy as an example. To raise an object from one position to another position one meter higher takes a certain amount of energy - the potential energy of the object increases. The amount of energy is independent of the path the object takes - whether it goes straight up, in zigzag, etc.
Yes. 10 x 10 = 102.
538J
One BTU is the energy required to raise one pound of water by one degrees. Therefore, your answer would be one half.
Potential Energy = mgh=1kg x 10m/s2 x 34.5m=345kg.m2/s2
A joule is defined as 1 kg being lifted 1 meter. Ergo 14 kilograms moved by 1 meter takes 14 joules.

Raise each part to the second power: (28xy)2 = 282x2y2 = 784x2y2.Raise each part to the second power: (28xy)2 = 282x2y2 = 784x2y2.Raise each part to the second power: (28xy)2 = 282x2y2 = 784x2y2.Raise each part to the second power: (28xy)2 = 282x2y2 = 784x2y2.

It is raised to the second power
possibly. For example, when you raise an 1-kg object one meter up very slowly, the potential energy of the object is increased by g [Joules], where g = gravity constant = 9.8 m/s2. The temperature of the object has not changed.
Multiply it by itself.
you guys should make a second one
yes. It takes energy to raise the temperature of the solid to the melting point.
Mass, heat capacity, the desired raise in temperature.
