How much potential energy does 60 kg skater have at 12 meters above ground?
The skater has potential energy of 7,056 joules.
How much potential NRG will a 20 kg ball at a height of 100 meters have?
The ball's potential energy will be 19,600 joules.
How much energy in joules is required to move a charge 6C through a difference in potential of 3V?
q=6C V=3V U=qV=(6C)(3V)=18 J U(potential energy)=18 Joules (18J)
Energy needed to move 4 coulombs of charge is 4 joules .the potential difference is how much?
The potential difference is 1 volt = 4J/4C.
How much is a energy in joules?
Unit of energy; approximately 4.2 joules
An object has 250 joules in total If 40 percent of this was potential energy how much potential energy is there?
Well, 40 percent of 250 I guess! Which, if you are not good at arithmetic is 100 Joules.
How much potential energy does 60 kg skater have at 12 meters above ground?
The skater has potential energy of 7,056 joules.
How much potential NRG will a 20 kg ball at a height of 100 meters have?
The ball's potential energy will be 19,600 joules.
Suppose a falling object loses 7J of potential energy. How much kinetic energy will it gain?
From what I understand: PE - Potential Energy (mgh) KE - Kinetic Energy (1/2 mv2) If one dismisses the friction with air (conservation of energy), a loss of 7 joules for potential energy means a gain of 7 Joules in kinetic energy.

q=6C V=3V U=qV=(6C)(3V)=18 J U(potential energy)=18 Joules (18J)
Energy needed to move 4 coulombs of charge is 4 joules .the potential difference is how much?
The potential difference is 1 volt = 4J/4C.

If a roller coaster has 100 joules of energy at the top of the first hill how much energy will it have at the bottom?
100. The amount of energy a roller coaster has is maintained throughout the whole journey. Its the conservation of energy - energy can' t be created or destroyed it can only be transferred. It therefore depends what type of energy you mean in the question. It can have a total of 100 joules meaning yes, anywhere on the roller coaster it will remain as 100 joules however if your saying 100 joules of gravitational potential energy at the top by the bottom of the hill it will have decreased and have been converted into at least 80 joules of kinetic energy leaving 20 joules as gravitational potential energy. Sorry for the poor grammar; just focus on the science. I have an exam on this in two weeks...
What is the unit of kinetic energy?
Joules, all energy is measured in joules.
How much energy is 500 joules?
500 joules is equal to 368.78 ft-lbf. For example, an object has 500 joules of kinetic energy, when its mass is 10 kg (~22 lbs) and it is traveling at 10 m/s (36 km/h or ~38.2 ft/s). Second example: The muzzle energy of a traveling 9mm bullet is around 500 joules. Third example: An object with mass of 5kg (11 lbs) and which is raised at 10 metres (32.8 ft) has around 500 joules of potential energy. So, 500 joules is quite much. Getting hit with an object which has 500 joules of kinetic energy can be lethal.
How much energy is needed in Joules for a 90 kg woman was to climb a ladder 6 meters in height?
The energy needed for a woman to climb a ladder is given by the change in potential energy she experiences. Defining the ground as being zero potential energy, her overall change in potential energy isEp = mghwhere Ep is the change potential energy, m is her mass, g is the gravitational acceleration (9.8m/s2 on earth) and h is the height she climbs.Ep = (90kg)(9.8m/s2)(6m) = 5292kg*m2/s2 or 5292 Joules
How much electrical energy is required to move 4.00 mC of charge through a potential difference of 36.0 V?
0.144 JOULES. One can calculate this from the formula E=Vq in which E is energy, V is potential difference & q is charge.
