Physics question (multiple choice)
when the number of electrons striking the anode of an x-ray tube increases, the of the emitted x-rays increases.
a) number
b) frequency
c) energy
d) wavelength

A) number

Explanation:

As we know that in production of X rays when high energy electrons collide with the anode then in each collision the kinetic energy of electron will release its kinetic energy in form of photons.

So here if more number of electrons collide with anode then more number of photons will release.

So here since number of photons are more due to increase number of collision so we will have more intensity of X rays

So here correct answer will be

A) number

the cellphone, they would then know if the killer would have contacted them or always hated them. or if it was a breakup. but if that is not the case, then it would be the clothing. to put in a bullet, it would have to be put in by hands. hands have finger prints which, would have giving you the answer of who done it.

explanation:

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
