Explanation:
what is the smallest crater that each of these telescopes could resolve on our moon?
For moon ;
s = 3.8 × 10 ⁸ m
y = 1.22 λs/D
where;
λ = 400 nm = 400× 10 ⁻⁹
D = 2.4 m
The smallest crater for the hubble space is calculated as follows:
For Aceribo ;
y = 1.22 λs/D
where :
λ = 75 cm = 0.75 m
D = 305 m
1) The electric potential at a distance r from a single point charge is given by
where k is the Coulomb's constant, q is the charge and r is the distance from the charge.
The charge in this problem is
So the potential at distance
is
2) By using the same formula as before, we can find the electric potential at distance r=99 m from the charge:
where k is the Coulomb's constant, q is the charge and r is the distance from the charge.
The charge in this problem is
So the potential at distance
2) By using the same formula as before, we can find the electric potential at distance r=99 m from the charge:
