Answer:
the planet which is like earth and have suitable environment for living is called exoplanet
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:
The angular speed is 4.22 rpm.
Explanation:
Given that,
Length of arm = 6.75 m
Mass of Europa
Diameter = 3120 km
We need to calculate the angular speed
Using formula of gravitational force
Put the value into the formula
Hence, The angular speed is 4.22 rpm.
