Answer:
The galaxy is moving away from us
Explanation:
Galaxy refers to a system of millions or billions of stars accompanied by gas and dust such that they are held together as a result of gravitational attraction.
When we observe a distant galaxy, we find that a spectral line of hydrogen that is shifted from its normal location in the visible part of the spectrum into the infrared part of the spectrum.
It means that the galaxy is moving away from us.
Answer:
a
all the molecules or atoms in motion has kinetic energy
The maximum torque she can apply to the spark plug is 12.76 Nm.
<h3>
What is torque?</h3>
Torque is the rotational equivalent of linear force obtained by taking the product of force and the radius of the applied force.
τ = Fr
where;
- F is the applied force
- r is the radius
The maximum torque she can apply to the spark plug is calculated as follows;
τ = 58 x (0.22)
τ = 12.76 Nm
Thus, the maximum torque she can apply to the spark plug is 12.76 Nm.

Complete Question:
Find the resistance of a wire of length 0.65 m, radius 0.25 mm and resistivity 3 * 10^{-6} ohm-metre.
Answer:
Resistance = 9.95 Ohms
Explanation:
<u>Given the following data;</u>
Length = 0.65 m
Radius = 0.25 mm to meters = 0.00025 m
Resistivity = 3 * 10^{-6} ohm-metre.
To find the resistance of the wire;
Mathematically, resistance is given by the formula;
Where;
- P is the resistivity of the material.
- L is the length of the material.
- A is the cross-sectional area of the material.
First of all, we would find the cross-sectional area of the wire.
Area of circle = πr²
Substituting into the equation, we have;
Area = 3.142 * (0.00025)²
Area = 3.142 * 6.25 * 10^{-8}
Area = 1.96 * 10^{-7} m²
Now, to find the resistance of the wire;
<em>Resistance = 9.95 Ohms </em>

1 Frequency
2 Wavelength
3 Amplitude
4 Crest
