The speed of electromagnetic radiation of all kinds, including light, is faster than the speed of anything else.
alpha radiations travel with different speed depending upon the source they are emitted from
radiation radiation travels at the speed of light, which is very quick diffusion is slow. convention is faster than diffusion.
No, they travel at the same speed.
The speed is variable; faster while closer to the Earth, and slower further away. But the actual speed varies by the orbital distance.
No. The speed of the moon's orbit does not depend on Earth's spin; it depends on Earth's mass. However, a faster spin on Earth's part would make the moon appear to move across the sky faster, as it would for the sun and stars.
No
No. All forms of electromagnetic radiation travel at the speed of light.
Beta particles or radiation is an electron emitted at high speed or energy from some types of unstable elements in a process known as beta-decay. Beta radiation is not healthy for living things. It is usually stopped by a few millimeters of metal, wood, or plastic. Direct exposure to the skin can cause radiation burns.
Cherenkov radiation is electromagnetic radiation generated when subatomic particles pass through matter at a speed faster than the speed of light through that type of matter. It is somewhat analogous to the sonic boom generated when objects pass through air faster than the speed of sound; except Cherenkov radiation is an electromagnetic phenomenon and a sonic boom is a sound phenomenon. Cherenkov radiation is usually seen as blue light. It is most commonly seen in the water surrounding nuclear reactor cores (see photo above), but can also occur in any transparent material (e.g. air, plastic, glass) when it is exposed to enough high speed subatomic particle radiation.
The Moon's orbital speed is greatest when it is at its closest approach to the Earth.
