Our solar system consists of the sun and the 9 planets and their moons.
The galaxy is outside our solar system.
Solar cells are used to trap sunlight energy (light energy) and convert it to electric energy for domestic and other purposes.
The energy absorbed by photon is 1.24 eV.
This is the perfect answer.
So the equation for angular velocity is
Omega = 2(3.14)/T
Where T is the total period in which the cylinder completes one revolution.
In order to find T, the tangential velocity is
V = 2(3.14)r/T
When calculated, I got V = 3.14
When you enter that into the angular velocity equation, you should get 2m/s
Gravitational attraction / field strength increases when closer; A light dependent resistor (LDR) can be used as a sensor to detect light intensity.
