Answer:
Neutrons
Explanation:
Isotopes are atoms with same protons and different neutron number. For eg: Hydrogen has 0 neutrons. But a stable isotope of hydrogen called Deuterium has 1 neutron but both still have 1 proton which makes them isotopes.
Thompson suggested that the atom is a positively charged sphere where electrons are embedded inside it.
Answer:
Density is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.

Kinetic energy is 1/2m*v^2
They already halved the mass for you and they already squared the velocity for you. I’m unsure why you’re even asking this question. It’s simple multiplication at this point.
(27.5kg)*(4m^2/s^2) = 110 Jules
transverse wave
A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves.
