Explanation:
w = f x d
45 x 1.4 = 630j
to get newton's do 45 x gravitation field strength
The power applied to move the box anywhere is
(20 n) x (distance moved) / (time to move the distance) .
C. Clear, dry weather. A good way to remember is H for high pressure = H for happy weather; L for low pressure = L for lousy weather (Glad I had someone to tell me this)
7kinetic energy is decreasing in B
Answer:
λ = 5.656 x 10⁻⁷ m = 565.6 nm
Explanation:
Using the formula of fringe spacing from the Young's Double Slit experiment, which is given as follows:

where,
λ = wavelength = ?
Δx = fringe spacing = 1.6 cm = 0.016 m
L = Distance between slits and screen = 4.95 m
d = slit separation = 0.175 mm = 0.000175 m
Therefore,

<u>λ = 5.656 x 10⁻⁷ m = 565.6 nm</u>
