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.
Explanation:
Force = (mass) · (acceleration)
= (1,000 kg) · (9.8 m/s²)
= 9,800 newtons
Why are you still having a problem with F = M · a ?
The molar latent enthalpy of boiling of iron at 3330 K is ΔH = 342
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
10^-3
(p) (ΔH) / (8.31) (3330)^2 = 3.72
10^-3
ΔH = 342
10^3 J.
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.
