Answer:
(a) 
(b) 
Explanation:
The average power is defined as the amount of work done during a time interval:

According to work-energy theorem, the work done is equal to the change in kinetic energy. So, we have:

Recall that the weight is given by:

The car accelerates uniformly from rest (
). Replacing (3) in (2), we have:

(a) Finally, we replace this in (1):

(b)

Answer:
I would say B. Just because all the other options are very common in sports
Explanation:
Answer:
B
Explanation:
Is the equilibrium stable or unstable for the third charge
Since an alpha particle has 2 protons and no negative particles (electrons) to balance the net charge, its charge is
Q=2(1.6e-19)=3.2e-19C.
The force on a charged particle is F=QE so
(3.2e-19C)(600N/C)=1.92e-16N
Answer:
Gamma Rays
Explanation:
Gamma rays have the highest energies the shortest wavelengths and the highest frequencies. They have the highest energies because they have the highest frequencies, the higher the frequency the more energy. ( I think, maybe double check with other answers )
Good Luck :)
