Explanation:
According to law of conservation of energy, energy can neither be created nor it can be destroyed. It can only be transformed from one form to another.
Therefore, when pendulum is at highest point of its swing then it had only potential energy and zero kinetic energy. But when swing reaches at the bottom then potential energy converts into kinetic energy as height is zero.
Hence, potential energy = kinetic energy.
Thus, we can conclude that kinetic energy at the bottom of swing of pendulum is 359 J.
J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged "soup."

Aluminium Chloride and Hyrdron, also known as proton/
Explanation:
Answer:
Apparent magnitude
Explanation:
By definition, Apparent magnitude which is usually denoted by "m" is the measure of the brightness of a star or even other astronomical objects that are observed from Earth. Meanwhile the absolute magnitude is defined as the intrinsic luminosity emitted by a star or other astronomical objects.
Thus, apparent magnitude is correct.
