How is electrical energy changed to light energy in a circuit?
Either by the current heating a fine wire until it glows in the incandescent lamp, by an electrical discharge exciting agas or flourescent material in gas-discharge and flourescent lapms respectively, or by a quantum effect in the light-emitting diode.
How do you determine the half life of a radioactive substance that has changed through radioactive decay After 40 days the original substance left is is one sixteenth of the original amount?
the halflife is 10 days
How much the temperature of a material is changed by heat energy depends?
It depends on the amount of material (its mass), on how much heat energy is added, and on the material's heat capacity.
Can sound energy be changed into another form of energy?
Yes. For a start, if sound gets absorbed by some material, it is converted into heat.
Which of the following can change the rate of radioactive decay?
For all practical purposes, No. However, there is a very small effect on some elements due to pressure (E.g. http://www.sciencemag.org/cgi/content/abstract/181/4105/1164), there is a small effect upon Beta Decay due to magnetic field strength, and there is an effect due to ionization.
How the radioactive decay rate be changed?
The rate cannot be changed.

How is electrical energy changed to light energy in a circuit?
Either by the current heating a fine wire until it glows in the incandescent lamp, by an electrical discharge exciting agas or flourescent material in gas-discharge and flourescent lapms respectively, or by a quantum effect in the light-emitting diode.
Has Uranium changed over time?
The chemical and physical properties of uranium remain unchanged. But because uranium is a radioactive element the quantity of uranium on the earth is permanently changed due to radioactive decay.
Does the process of radioactive decay fall under the study of chemistry or physics or is it a combination of both?
Radioactive decay falls under chemistry, because the chemical properties of the substance are changed during radioactive decay.
