<span>A. light and radio waves
Light is also known as electromagnetic waves. This is because light is actually both an electric and magnetic field. Though it does not seem like it, light does not contain a charge but rather an </span>oscillating field. You can see this happening in your TV. There is no isolated magnetic charge for electromagnetic waves, so you won't be able to do something like put a magnet on the waves.
Its when one species marries another species
Explanation:
It correctly reads;
A group of students use a device to study the energy transfer during the chemical reaction between pieces of eggshell (calcium carbon) and vinegar (acetic acid). During the experiment they use the same mass of eggshell but the concentration of the vinegar varies, (1%, 3% and 5%). Answer:
1. Explain why the energy transfer is not the same between the three tests of the experiment.
2. Describe how the device could be modified so that it can MORE ACCURATELY measure the energy transfer in each reaction.
