The following unit measure energy?
814582
(a) is the correct answer.
711054
It's two.  Energy goes as the square of amplitude.

The unit would be the volt: http://physics.nist.gov/cuu/Units/units.html

Is relative to the amount of energy and object contains.

It depends if it is acting as a Force or a Pressure (a distributed Force). If it is a force, it has units of N (Newtons, or kg m/s²) and if it is a pressure it has units of Pa (Pascals, or N/m² which is the same as kg/(m s²))

Energy equals mass times the speed of light squared

Potential energy is generally measured from a reference point of your choosing. If you choose the reference point (zero) to be above a point in the systen than you are at negative potential energy.

Absolute zero refers to 0 degress Kelvin -- a measure of temperature.\n\nA Joule is the "metric" standard measure of energy.\n\nCalories are an older measure of thermal energy.\n\n1 Calorie = 4.18 Joules.
68493
Energy is defined as being equivalent to Mass times the Speed of Light, Squared...\n\nE=MC(2)
223576
Watt.\n\nWatt is used to measure power or the rate of doing work. One watt is a power of 1 joule per second.
781911
None.\n\nCalories are a measure of the heat content of objects.  If you are referring to the amount of heat radiated by the earth, it would be stated in some unit appropriate to the measure of radiant energy, such as watts or newtons per second.\n\nYou may be able to find an answer by visiting the library or using the internet.

I agree; c) is the right choice.  The other units are used to measure:\n\na)  power ratio\nb)  pressure\nd)  pressure (again)

It is the energy possessed by a moving electron through a potential difference of 1 volt.\nThis is the unit of energy in atomic Physics.\n2.247x10^25 ev units are equal to 1 kWh.

E=mc^2 is a formula not a problem.\n\nE stands for energy\nM stands for mass\nC stands for speed of light\n\nwith it you can figure out how much energy is in a given amount of matter.
953904
No common denominator for the energy in the things you mention except that if it has mass, then it embodies the energy given in E = mc^2\n\nThis applies to ALL matter.
398556
A joule which is broken down into kg*(meters/second)^2\n\n(^2 means squared)\n\nAlso, 1 calorie = 4.184 joules.

Energy is defined as the ability to do work.  It is a measurment of how much you would be able to move an object through a specific distance.  It is measured in Joules.\n\nThere are various means of calculating the amount of energy stored in things.  For electromagnetic waves it gets a little complicated.  But suffice it to say that electromagnetic waves have energy stored in them.  You can do work with an electromagnetic field by seeing it's effect on a magnetic.  The bar of magnet moves, so energy is being expended....\n\nMass is defined as a measurement of how much matter an object contains.  It is measured in kilograms.\n\nWaves really are just a transmission of energy.  Sound wave, you move air particles and the energy travels through the air.  Electromagnetic Waves, you move a magnetic, and current is induced in a wire, or waves propagate through the air (movement transfered to EM waves).
