Discuss the factors that are used to determine power.
2 answers:
Answer : current , voltage and resistance
Explanation: Three factors are used to power.
Current , voltage and resistance
When we find the power then we need the voltage, current and resistance.
We use the ohm's law and find the power
Firstly we will use the ohm's law
Now, the power is
...(i)
Put the value of V in equation (i)
This is the formula of power and factors of the power is current , voltage and resistance. Watt is the unit of power.

Answer:
The acceleration of the proton is 2.823 x 10¹⁷ m/s²
The acceleration of the electron is 5.175 x 10²⁰ m/s²
Explanation:
Given;
distance between the electron and proton, r = 7 x 10⁻¹⁰ m
mass of proton, = 1.67 x 10⁻²⁷ kg
mass of electron, = 9.11 x 10⁻³¹ kg
The attractive force between the two charges is given by Coulomb's law;
where;
k is Coulomb's constant = 9 x 10⁹ Nm²/c²
Acceleration of proton is given by;
F = ma
Acceleration of the electron is given by;
