The redshift of a star means that _____.
Gelneren [198K]
The correct answer is D. the star is getting farther away.

When the light has red-shifted, it shows that everything is moving away from a certain point. This is known as the Doppler effect and proves the Big Bang (which would be the center point that everything is moving away from). Just as a 'for your information', blue shift is when the star is moving towards us.

Hope I helped :)

3. As the ice melts into liquid water, what happens to the kinetic energy of the particles in the sample?
rusak2 [61]

Answer:

As ice melts into water, kinetic energy is being added to the particles. This causes them to be 'excited' and they break the bonds that hold them together as a solid, resulting in a change of state: solid -> liquid.

Determine the kinetic energy of a 1000-kg roller coaster car that is moving with a speed of 20.0 m/s.
ankoles [38]

Answer:

The correct answer is - 200000 J

Explanation:

We use the formula of kinetic energy:

The formula to calculate kinetic energy is,

Here,

Ec =1/2 x  m x v^2

The mass of the roller coaster is,  m  =  1000  k g

The speed of the roller coaster is, v = 20.0 m/s

 Therefore,

Ec=1/2 x 1000kg x (20m/s)^2 = 200.000Joule

200,000J

The two ends of a coiled wire are connected to the electrodes of a lightbulb.
barxatty [35]

Answer:

a

Explanation:

The bar magnet moves downward with respect to the wire loop, so that the number of magnetic field lines going through the loop decreases with time. This causes an emf to be induced in the loop, creating an electric current.

in other words, the magnets motion creates a current in the loop
