The force between the charges is 60.47N
<u>Explanation:</u>
Given:
Charge, q₁ = 2.5 X 10⁻⁶ C
q₂ = 4.3 X 10⁻⁶ C
Distance, r = 0.04m
Force, F = ?
According to Coulomb's law:
where,
k = Coulomb's constant
and the value of k is 9 X 10⁹ Nm²/C²
On substituting the value we get:
Therefore, the force between the charges is 60.47N
In Nuclear Fusion, the reaction is involved in the merging of small atoms and high energy is produced, while in Nuclear Fission, it involves in the splitting of large atoms wherein radoactive isotopes are involved.
Answer:
Hence the order of the bright fringe is 7.
Explanation:
Diffraction can be defined as the deviation from rectilinear propagation and diffraction grating is used to measuring the wavelength of light using a spectrometer.
We have the formula d sin∅ = n l
We have to find the value of n in this equation and all other values are given.
Here d = 55000 lines
∅ = 12.23°
Wavelength , l = 550 nanometer
n is the order of the bright line.
Substitute these values in the given equation,
55000 sin(12.23°) = n
n = 7
Hence the order of the bright fringe is 7.

2.) 10 MJ
Explanation:
Given that a coal power plant station generates electricity at night when it is not needed. Some of this energy is stored by pumping water up to a mountain lake. When there is high demand for electricity, the water is allowed to flow back through a turbine to generate electricity.1- Write down the forms of initial and final energy transfer.
Solution.
The initial conversion will be :
Chemical energy is converted to mechanical energy.
The final conversion will be :
Mechanical energy is converted to electrical energy. While the electrical energy is converted to light energy.
2- On one occasion, 2000 kg of water is pumped up through a vertical height of 500 m. Calculate the gravitational potential energy. (g= 10 m/s^2)
The gravitational potential energy can be calculated by using the formula
Energy = mgh.
Where
M = mass
H = height
g = acceleration due to gravity
Substitute all the parameters into the formula
Potential Energy = 2000 × 500 × 10
Potential energy = 10000000 Joule
Potential energy = 10 MJ
