Explanation:
30 minutes is 1800 seconds.
Power = energy / time
P = 1100 J / 1800 s
P = 0.611 W
Converting the energy from J to kWh:
1100 J × (1 Ws / 1 J) × (1 kW / 1000 W) × (1 h / 3600 s) = 3.06×10⁻⁴ kWh
To find resistance, you need to be given either the voltage or the current.
Answer: 0
Explanation: Initial velocity is 0.
Answer:
- The diameter of the molecule of oil is
Explanation:
We define density as
So, the volume for our oil will be
the volume for a cylinder with radius r and height h is
So, we can obtain the height of the droplet of oil as:
the radius is
And this is the diameter of the oil molecule.
this is due to the existence of other forces called the strong nuclear forces that overcomes the repulsion forces between the protons and keeps the nucleons holding to each other also there is a type of energy that is called the nuclear binding energy and this energy also works on binding the components of the nucleus together
