Answer:
It is worth noting that the higher the gravitational energy of an object moving downwards, the lower the kinetic energy, and the lower the kinetic energy of an object moving upwards, the higher its gravitational energy.
Gravitational potential energy is acquired by an object when it has been moved against a gravitational field. For example, an object raised above the surface of the Earth will gain energy, which is released if the object is allowed to fall back to the ground.
Answer:
∅=2021rad
Explanation:
Coherent light with wavelength 540 nm passes through narrow slits with a separation of 0.370 mm . At a distance from the slits which is large compared to their separation, what is the phase difference (in radians) i the light from the two slits at an angle of 28.0 ∘ from the centerline?
A wave is a disturbance which travels through a medium, it transfers energy without a permanent displacement of the medium itself. this is an example of light wave
using the formula below
∅=
the phase difference is given from the above
d= distance/separation of slits .00037m
=wavelength
540*10^-9m
=angle of two slits 28.0 ∘
∅=(
∅=2021rad
there are large bright fringes from the centre line
Measurements in physics is important because it enables people to argue using mathematics where numbers can be used to represent knowledge in a convenient manner when we show and communicate about a phenomenon.
Explanation:
When a physician is able to measure a phenomenon, then we get a foundation of understanding a lot of things in our universe.Measuring these things will help know how to use them in various applications.

Albert Vanfleet i know this because he flew over in 1976 and found a job studying physics. He became well known for his work in 1983.
