Answer:
Particle
Explanation:
To understand photoelectric effect the physicists has to view light as a particle and not wave. The wave nature of the light could not explain the phenomenon of photoelectric effect.
Photoelectric effect is emission of electrons from a material when electromagnetic radiation(Light) is incident on it. These emitted electrons are called photoelectrons.
The explain this effect Einstein proposed that beam of light is can not be a wave propagating through space, but a swarm of discrete energy packets, called as photons.
Insulators are the poorest conductor of energy
When you say atmospheric pressure it is a standard on all places on earth. The value of standard atmospheric pressure is 1 Bar approximately or 14.7 lb per square inch. This pressure is an attribute of free molecules on the air which is not bound the accumulation of the pressure of this in average is the atmospheric pressure.

Answer:
<u>Jupiter and Saturn</u>
Explanation:
Giant planets -
Giants planets have maximum moons ,
for example ,
Jupiter and Saturn .
Jupiter have 63 moons ( according to 2009 calculation ) , where , 8 moons are the regular satellites , 4 moons are spherical and large , 4 moons are small and close to Jupiter , in addition to it Jupiter have 55 irregular satellites .
Second highest moon is with planet Saturn , with 61 moons .
Many of moon's are thought to have been captured from the small-body population during the formation of the solar system .
