Answer:
The two different ways to measure gravitational potential energy is listed below:
Explanation:
- To measure the gravitational potential energy of the ball dropped from certain height we can use the formula as:
PE= mgΔh
where,
m= mass of the ball
g= gravity
Δh= change in height
- The second way is to follow the principal as:
Loss in PE = Gain in KE
∴ -ΔPE = ΔKE
- Height and mass is the major element that determines the gravitational potential energy of any object.
Answer:
know the truth.’ Then I said: ‘Blessed be God, who put this in the Chan’s heart. But our Scriptures tell us, the servant of God should not dispute, but should show mildness
Answer:
just-noticeable difference
Explanation:
Using principles of psychology and physics, a branch of experimental psychology called psychophysics has been created. This field is focused on the sensation, the sense and the perception of stimuli. Within this branch it has been called just-noticeable difference to the amount that must be changed of some stimulus so that this difference is noticeable, that is to say, the threshold at which the change is perceived.
Answer:
d = 3.56 x 10⁻⁴ m = 0.356 mm
Explanation:
The diameter of the aperture can be found using the following formula:
where,
y = distance between dark rings = 1.65 mm = 1.65 x 10⁻³ m
λ = wavelength = 490 nm = 4.9 x 10⁻⁷ m
L = distance between screen and aperture = 1.2 m
d = diameter of aperture = ?
Therefore,
<u>d = 3.56 x 10⁻⁴ m = 0.356 mm</u>
