In 6–8 sentences, write a summary of what you learned from this activity. Include an explanation of what causes the spectral shi
QveST [7]

Answer :First part is what you learned so write what you learned then the other parts is The evidence that the universe is expanding comes with something called the red shift of light. Light travels to Earth from other galaxies. As the light from that galaxy gets closer to Earth, the distance between Earth and the galaxy increases, which causes the wavelength of that light to get longer.

What is the force on a 1,000 kilogram-elevator that is falling freely under the acceleration of gravity only?
likoan [24]

           Force = (mass) · (acceleration)

                     = (1,000 kg) · (9.8 m/s²)

                     =      9,800 newtons

Why are you still having a problem with      F = M · a  ?

At the normal boiling temperature of iron, TB = 3330 K, the rate of change of the vapor pressure of liquid iron with temperature
Margaret [11]

The molar latent enthalpy of boiling of iron at 3330 K is  ΔH = 342 \times 10^3 J.

<u>Explanation:</u>

Molar enthalpy of fusion is the amount of energy needed to change one mole of a substance from the solid phase to the liquid phase at constant temperature and pressure.

                      d ln p = (ΔH / RT^2) dt

                   (1/p) dp = (ΔH / RT^2) dt

                    dp / dt = p (ΔH / RT^2) = 3.72 \times 10^-3

                  (p) (ΔH) / (8.31) (3330)^2 = 3.72 \times 10^-3

                          ΔH = 342 \times 10^3 J.

How are the magnetic field lines near the south pole of a magnet affected when a second south pole is brought near it?
KonstantinChe [14]

Explanation:

Magnetic field is the surrounding around the magnet in which the magnetic force can be experienced.

Same poles of the magnets repel each other. The opposite poles of the magnets attract each other.

In a magnet, the magnetic field originates from the north pole and ends to south pole.

In the given problem, the south pole of a magnet get affected when a second south pole is brought near it. These poles will repel each other as both are south poles. Here, the magnetic field lines near the south pole of a magnet gets bend away from the south pole of the second magnet.
