Answer:
It is the best angular resolution the telescope could achieve with perfect optical quality and in the absence of atmospheric distortion.
Explanation:
When looking through a telescope or microscope due to imperfections of the lenses or misalignment, two sources may appear. The angular space between these two sources can be found by calculating the wavelength of the light observed divided by the diameter of the telescope.
Answer:
a) Vb = 4.65m/s at 25.46° due south of east
b) t = 119s
c) d = 238m
d) 28.43° due north of east.
e) Vb = 3.69m/s due east
f) t = 135.5s
Explanation:
Velocity relative to the earth is:
Vb = 4.65m/s < -25.46°
Since the distance to travel is 500m:
The distance on the y-axis is given by:
If the final position is directly east from the starting position:
From the y-components:
Solving for β:
β=28.43°
With this angle, the velocity would be:
Vb = 4.2*cos(28.43°) = 3.69m/s
And the time it would take it to cross:
t = 500/3.69 = 135.5s
Answer:
There is a localization of negative charge near the door handle.
Explanation:
For a circular orbit v= with G = 6.6742 ×
Given m = 6.42 x 10^23 kg and r=9.38 x 10^6 m
=> v = 2137.3 m/s
I hope this is the correct way to solve
Answer:
one half as large , initial velocity is two times larger
Explanation:
Momentum is conserved.
p₁ + p₂ = p₁' + p₂'
m₁v₁ + m₂v₂ = m₁v₁' + m₂v₂'
m₁ = m₂ =m , v₂= 0
v₁' =v₂'
mv₁ = 2mv₁'
v₁ = 2v₁'
