A redshift reveals how an object in space (star/planet/galaxy) is moving compared to us. It lets astronomers measure a distance for the most distant (and therefore oldest) objects in our universe
Your answer is 392.28 newtons on earth
Explanation:
It is given that,
Distance between the slits, d = 5 mm = 0.005 m
Distance between slit and screen, D = 1.4 m
For m = 2, and
For m = 2, and
Separation between two fringes is :
Hence, this is the required solution.
Answer: Option (c) is the correct answer.
Explanation:
According to the second law of motion mass of an object times its acceleration is equal to the net force on the object.
Mathematically, F = ma
Generally, mass is expressed in kilograms (kg) and acceleration is expressed as follows.
acceleration =
=
=
Hence, S.I unit of acceleration is .
Therefore, units of force will be as follows.
F = ma
=
Thus, we can conclude that gives the correct units for force.
