Static electricity is caused by the build up of charges on surfaces of objects while electric current is the constant flow of electrons along a conductor (the rate of flow of charge).
Because rockets do accelerate in space and have been able to do so for a long time.
Answer: Option D
<u>Explanation:</u>
A rocket is made to reach the sky and its required destination by the burning of fuels in the rocket. So there is no need of any other external forces to propel them in space. As per Newton's third law, the action and reaction forces will help the rockets to escape the orbit of earth.
And then the remaining energy required by the rocket to travel in space will be obtained from the burning of fuels in the compartments. This burning of fuels in respective compartments will propel the rockets in space. So it is a complete myth that space travel was impossible before because of inability to provide propulsion in space.
Answer: should be called meteorite
The scientists error is that he refers to the meteorite as a meter however it should be classified as a meteorite since 1 it mostly consists of iron and nickel and 2 it is already on the earths surface.
Answer:
Its B, C, E
Explanation:
Have a great day everyone:)
Answer:
An electron shell is the outside part of an atom around the atomic nucleus. It is a group of atomic orbitals with the same value of the principal quantum number n. Electron shells have one or more electron subshells, or sublevels.
Explanation:
The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6), The 4th shell can hold up to 32 electrons.
I don't know the last one though
