The answer is: Diameter = d = 6.1 cm
Explanation:
Angular separation between the two stars = Q = 10^-5 rad.
Wavelength =λ= 500 * 10^-9 m
The smallest diameter = d = ?
As Q = 1.22*(λ/ d)
From this
d = 1.22*(λ/Q) --- (1)
Plug in the value in (1):
(1) => d = 1.22*((500*10^-9)/10^-5))
d = 0.061 m
d = 6.1 cm
Well you could drive stakes or piers down into the bedrock to anchor it, but you would still need to be cautious of erosion.
Answer:
The answer to your question is: F = 50 N
Explanation:
Data
mass = 1000 kg
acceleration = 0.05m/s2
F = ?
Formula
F = m x a
Substitution
F = 1000 kg x 0.05 m/s2 = 50 kgm/s2 = 50 N
Mike is applying a force of 50 N to the car.
