It’s cause by the fact that the earth is tilted 23.5 degrees
The age of the galaxy when we look back is 13.97 billion years.
The given parameters:
- <em>distance of the galaxy, x = 2,000 Mpc</em>
According Hubble's law the age of the universe is calculated as follows;
v = H₀x
where;
H₀ = 70 km/s/Mpc

Thus, the age of the galaxy when we look back is 13.97 billion years.

Answer:
The capacitance of the deflecting plates is
.
Explanation:
The expression for the capacitance of the capacitor in terms of area and distance is as follows;

Here, C is the capacitance, A is the area, d is the distance and
is the absolute permittivity.
Convert the side of the square from cm to m.
s= 3.0 cm
s= 0.030 m
Calculate the area of the square.

Put s= 0.030 m.


Convert distance from mm to m.
d= 5.0 mm

Calculate the capacitance of the deflecting plates.

Put
,
and
.



Therefore, the capacitance of the deflecting plates is
.
