The correct answer is #4. They have the same number of protons but a different number of neutrons.
Answer:
They interact in a lot of ways, prey, predator, etc.
Answer:
T²= 4π²R³/GM
Explanation:
First we know that
Fg= Fc
Because centripetal force must equal gravitational force
So
GMm/R² = Mv²/R
But velocity is 2πR/T
So by substitution we have
GMm/R²= M (2πR/T)/T
We have
T²= 4π²R³/GM as period
Explanation:
It is given that,
Net force acting on the electron,
Displacement, d = 5 cm = 0.05 m
(a) Let is the change in kinetic energy of the electron. It can be calculated using work energy theorem. Mathematically, it is given by :
(b) Initial speed of the electron, u = 0
Again using the work energy theorem as :
Hence, this is the required solution.
