Answer:
14869817.395 m
Explanation:
=22 microarcsecond
λ = Wavelength = 1.3 mm
Converting to radians we get
From Rayleigh Criterion
Diameter of the effective primary objective is 14869817.395 m
It is not possible to build one telescope with a diameter of 14869817.395 m. But, we need this type of telescope. So, astronomers use an array of radio telescopes to achieve a virtual diameter in order to observe objects that are the size of supermassive black hole's event horizon.
When an electron in a hydrogen atom transitions from the state of n=6 to n=1, a photon with an energy of 13.2 eV is released.
<h3>What components make up a photon?</h3>
- A photon is a microscopic particle that is part of electromagnetic radiation waves.
- Maxwell demonstrated that photons are merely electric fields flowing through space.
- A single photon can trigger a response from sensors in the retina.
<h3>What is the difference between an electron and a photon?</h3>
- Photons and electrons. One of the fundamental quantum-mechanical particles is an electron, although photons also exist and have entirely distinct properties.
- While the electron is a subatomic particle found in every atom, the photon is a sort of elementary particle that serves as an energy carrier.

Answer:
ρ=0.0102lbm/ft^3
Explanation:
To solve this problem we must take into account the equation of continuity, this indicates that the sum of the mass flows that enter a system is equal to the sum of all those that leave.
Therefore, to find the mass flow of exhaust gases we must add the mass flows of air and fuel.
m=0.59+60=60.59lbm/s( mass flow of exhaust gases)
The equation that defines the mass flow (amount of mass that passes through a pipe per unit of time) is as follows
m=ρVA
Where
ρ=density
V=velocity
m=mass flow
A=cross-sectional area
solving for density
ρ=m/VA
ρ=60.59/{(1485)(4)}
ρ=0.0102lbm/ft^3
100 cm is 1 meter. So your answer would be 0.362 meters.
Answer
Work done will be equal to 1229.296 J
Explanation:
We have given mass of the sister m = 25 kg
Angle between rope and ground 
Force F = 30 N
So horizontal force 
Distance traveled d = 52 m
'We have to find the wok done
Work done is equal to multiplication of horizontal force and distance
So work done
