F = ma
F = Force
m = mass = 2500 kg
a = acceleration = 3 m/s2
Plug in the the numbers and compute the answer. The units are Newtons (kg·m/s2)
Answer:
The mass of the rock is
Explanation:
From the question we are told that
The length of the string is
The angular velocity is
The tension on the string is
Generally the centripetal force acting on the rock is mathematically evaluated as
making m the subject of the formula
substituting values
Answer:
55.84 look at periodic table
so 55.84*3= 167.52gFe
highest energy level to the ground state.
Explanation:
The transition from the highest energy level to the ground state.
An electron has a discrete amount of energy accrued to it in any energy level it belongs to.
Electrons can transition between one energy level or the other.
- When electrons change state, they either release or absorb energy.
- When an atom absorbs energy, they move from their ground to final state which is consistent with the energy of the final state.
- When electrons release energy, they move from excited state to their ground state.
- Electrons will release the greatest amount of energy when they move from the highest energy level to the ground state.

Answer:
259.456 J
Explanation:
Given that,
Work done on the system = 166 cal
The systam releases 954 J of thermal energy to its surroundings
We need to find the change in internal energy. It can be given by using the first law of thermodynamics as follows :
W = 166 cal = 694.544 (1cal = 4.184 J)
So, the change in internal energy of the system is 259.456 J.
