When observed from Earth, the wavelengths of light emitted by a star are shifted toward the red end of the

Physics

Lilit [14]3 years ago

Answer: The redshift occurs because the starts are moving away from the earth.

Explanation:

Every object emits wavelength from its body. When it comes to universe there are some visible light emitted by the stars and other objects in galaxy.

If a star is moving towards the sun then it emits a shorter wavelength compared to the source which is at rest. This is blue in color called as blue shift.

But when it comes to stars they move away from the earth and hence emits longer wavelength called as red shift.

As the object it at rest it more towards the blue side and when the objects starts moving it starts moving towards the red side in the visible spectrum.

So, when the starts moves away from the earth it forms a Redshift.

The volume of an object as a function of time is calculated by v = At3+B÷t where t is time measured in seconds and v is in cubic
madam [21]

Answer:

A = m³/s³ = [L]³/[T]³ = [L³T⁻³]

B = m³s = [L³T]

Explanation:

We have the equation:

V = At³ + B/t

where, the dimensions of each variable are as follows:

V = m³ = [L]³

t = s = [T]

substituting these in equation, we get:

m³ = A(s)³ + B/s

for the homogeneity of the equation:

A(s)³ = m³

<u>A = m³/s³ = [L]³/[T]³ = [L³T⁻³]</u>

Also,

B/s = m³

<u>B = m³s = [L³T]</u>

How is acceleration calculated?
steposvetlana [31]

Answer:

Acceleration is the change in velocity divided by time

Explanation:

This is the correct answer because distance divided by time is the position. Speed multiplied by time is the distance. And acceleration is not just velocity, but the change in velocity over time.

If a closed series circuit has a voltage of 12 V and R1 = 4 Ω and R2 = 2 Ω, what is the current running through R1 and R2?
Phantasy [73]
Total resistance=R1+ R2= 6Ω
Voltage=12v
Current =\frac{voltage}{resistance}
Current= 2A
In a series circuit, equal current passes through every resistance.
