When you take the Doppler effect into account, it turns out that
the visible light emitted from a source moving away from Earth
will appear to have a wavelength longer than it really has, that is,
shifted toward the red end of the visible spectrum.

This is the only way we have of measuring whether a source of
light is moving away from us, and how fast.  We measure the
wavelengths of its light, and measure how much longer they are
than they should be. 

The main trick in this whole process is: When you see the light
from a star or a galaxy, how do you know what its wavelength
should be ?

The correct answer is:

redshift.

Explanation:

Redshift and blueshift describe how light shifts approaching shorter or longer wavelengths as objects in space (such as stars or galaxies) move closer or removed away from us. The knowledge is key to charting the universe's expansion. Visible light is a spectrum of colors, which is clear to anyone who has observed at a rainbow.

Suppose a 1300 kg car is traveling around a circular curve in a road at a constant
Scrat [10]

Answer:

F = 4212 N

Explanation:

Given that,

Mass of a car, m = 1300 kg

Speed of car on the road is 9 m/s

Radius of curve, r = 25 m

We need to find the magnitude of the unbalanced force that steers the car out of its natural straight-  line path. The force is called centripetal force. It can be given by :

F=\dfrac{mv^2}{r}\\\\F=\dfrac{1300\times 9^2}{25}\\\\F=4212\ N

So, the force has a magnitude of 4212 N

Imani stirs a cup of hot sencha tea with a cool silver spoon. She notices that the silver spoon becomes warmer. What energy chan
Lina20 [59]

Answer:

D. The tea loses heat to the spoon causing the spoon to become warmer

Explanation:

When the silver spoon at a lower temperature than the tea, is added to the tea, it makes thermal contact. Hence, the heat transfer starts between the two until the equilibrium is reached. We know that the heat transfer takes place from the body with a higher temperature to a body with a lower temperature. As a result, the body with higher temperature loses heat and its temperature lowers down. While the body with a lower temperature gains heat and its temperature rises.

Therefore, the correct option is:

<u>D. The tea loses heat to the spoon causing the spoon to become warmer</u>
