Chromosomes that's the answer
Answer:
D. ) The force would be zero newtons
Explanation:
Because
If you are at the center of the earth, gravity is zero because all the mass around you is pulling "up" (every direction there is up!)
So F=mg so if g is zero F is also zero
Answer:
Number of turns in secondary is 20
Current in primary is 0.96 A
Explanation:
We have given number of turns in primary
Voltage across primary of transformer
Current in secondary coil
Voltage across secondary
For transformer we know that
So
So number of turns in primary is 20
Now
Current in primary of transformer is 0.96 A
When the number of electrons striking the anode of an x-ray tube is increased, the <u>density</u> of emitted X-Rays increases.
Option: 1
<u>Explanation:</u>
As the electron speed increases, the heat radiation also increases from thermionic emission, which causes more heat and more X-ray release. X-rays are produced by an a vacuum tube called X-ray tube that uses more voltage to make the electrons accelerate which the hot cathode releases to a high velocity.
This high speed electrons meets in a collision with a metal target which is the anode, and thus create the X-rays. So, the electron number available and the time period set for their release from the filament determines how many x-rays are produced from the anode. Hence, more the number of electrons striking the anode,the more is the emission of x-rays.
