A specific amount of water would have the same mass even if you turned it from a liquid to a solid or a gas is an example of

a. law of definite proportions
b. law of conservation of mass
c. law of multiple proportions

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

What are similarities and differences between refraction, reflection, diffraction and absorption?
