Ep= mgh
Ep = 40 x 9.8 x 10
Ep = 3920J
Ep = 3900J (2sf)
Their Period number is common means their "Principal Quantum Numbers" are same
Hope this helps!
Answer:
9 times
Explanation:
Kinetic energy is:
KE = ½ mv²
When we triple the velocity, the kinetic energy increases by a factor of 9.
9KE = ½ m(3v)²
Answer is 4,400,000 kg • m/s
Answer:
When it’s gravitational
Explanation:
I’m pretty sure that’s the answer
