B because 2800 divide by 40 is 20
The atom carbon is the answer
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 :)
Answer:
He proposed that matter can be converted to energy and vice versa. He first discovered that nuclear-reaction products are lighter than the reactants. He developed the use of nuclear reactions to generate electricity

Answer:
a) 20.54 J
b) 30.97 J
c) 10.43 J
d) -20.54 J
Explanation:
m = Mass
g = Acceleration due to gravity = 9.81 m/s²
h = Height

Work done by the ball's weight is 20.54 J

Gravitational potential energy of the basketball, relative to the ground, when it is released is 30.97 J

Gravitational potential energy of the basketball, relative to the ground, when it is released is 10.43 J
Change in gravitational potential energy

Change in gravitational potential energy is given by -20.54 J
