Answer:
Explanation:
Given
mass of Flywheel 
mass of bus 
radius of Flywheel 
final speed of bus 
Conserving Energy i.e.
0.9(Rotational Energy of Flywheel)= change in Kinetic Energy of bus
Let 
be the angular velocity of Flywheel
The option is Work.
The product of charge and potential is equal to the energy. Adn, as we know work is related to energy as the capacity to do work.
Alos, because, Potential is given as, V = E/q
or E = Vq
Thus, t<span>he product of charge through, and potential across, an electrical device is:work

Answer:
Magnitude of resultant = 131.15
Direction of resultant = 3.97°
Explanation:
||u|| = 70
θ = 40°
||v|| = 85
θ = 335°
Resultant
Magnitude of resultant = 131.15
Direction of resultant = 3.97°
Answer:
gravitational force is a fundamental force and also , it does have a small range and is always an attractive force.
Explanation:
Answer:
With the help of formula.
Explanation:
We can calculate the electric potential of any point through the formula of electric potential which is given below.
Electric potential = Coulomb constant x charge/ distance of separation.
Symbolically it can be written as, V = k q/ r where
V = electric potential
k = Coulomb constant
q = charge
r = distance of separation
If we have all these data, we can simply put the data in the formula and we will get the value of electric potential.
