Answer:
C
Explanation:
they both have to be the same for both to not move
They move in a waves motion
If you're trying to sum it up, it would be 140 degrees c*, otherwise it would probably be 80 degrees c since its more hotter than 60 degrees
pitch is the perceived frequency of a sound wave.
Answer:
Explanation:
As we know that when electron moved in electric field then work done by electric field must be equal to the change in kinetic energy of the electron
So here we have to find the work done by electric field on moving electron
So we have
now the distance moved by the electron is given as
so we have
now we have to convert it into keV units
so we have
