Answer:
d = 2,042 10-3 m
Explanation:
The laser diffracts in the circular slit, so the process equation is
d sin θ= m λ
The first diffraction minimum occurs for m = 1
We can use trigonometry in the mirror
tan θ = Y / L
Where L is the distance from the Moon to Earth
Since the angle is extremely small
tan θ = sin θ / cos θ
Cos θ = 1
tant θ = sin θ = y / L
We replace
d y / L = λ
d = λ L / y
Let's calculate
d = 532 10⁻⁹ 3.84 10⁶/1 10³
d = 2,042 10-3 m
The complete cycle of moon phases runs 29.531... day. You're describing exactly half if that ... roughly 14.77 days.
Answer:
t=1s
Explanation:
Using the formula
s=ut+1/2at^2
4.9 = (0)(t) + 1/2(9.8)(t^2)
4.9 = 4.9(t^2)
t^2 = 1
t = 1

It is important to listen to your body to prevent injuries that can sometimes even be too big of a price to pay for victory. If you see that your body is struggling, or that your muscles and/or bones are straining/breaking, you definitely should take it easy so as to prevent injury.
