Power is the rate at which energy is consumed. When 1 J of energy is consumed in one second, the power consumed is 1 watt.
The microwave consumes 1.5 kJ of energy.
In joules, the energy consumed is 1500 J
Here, E is the energy consumed in time interval <em>t.</em>
The power rating of the microwave is therefore,
Thus, the power rating of the oven is 1500 W or 1.5 kW
Answer:
The electric force is
Explanation:
From the question we are told that
The Bohr radius at ground state is
The values of the distance between the proton and an electron
The electric force is mathematically represented as
Where n and p are charges on a single electron and on a single proton which is mathematically represented as
and k is the coulomb's constant with a value
substituting values
