Answer:
Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
Explanation:
Hello light it is a wave there for the answer is false
Answer:
greatest speed=0.99c
least speed=0.283c
Explanation:
To solve this problem, we have to go to frame of center of mass.
Total available energy fo π + and π - mesons will be difference in their rest energy:
=218 Mev
now we have to assume that both meson have same kinetic energy so each will have K=109 Mev from following equation for kinetic energy we have,
K=(γ-1)
note +-=±
To find speed least and greatest speed of meson we would use relativistic velocity addition equations:
I’m sure “save” is the correct answer, as it is the only grammatically correct answer choice. Also, it is easy to save when you know what you’ll have to pay for in the future.
Besides the Sun, planets and their moons, there are still other celestial bodies in the universe. Actually, there is more than what we know of. The universe is endless and timeless. It also contains stars, comets, asteroids, meteorites and the galaxies.
