Answer:

1. Absorbs electromagnetic energy

2. Energy difference between the two orbits.

Explanation:

Bohr precisely describe the processes of absorption and emission of energy in terms of electronic structure. According to Bohr's model, an electron would absorb energy in the form of photons to get excited to a higher energy level as long as the photon's energy was equal to the energy difference between the initial and final energy levels. After jumping to the higher energy level or the excited state, the excited electron would be in a less stable position, so it would quickly emit a photon to relax back to a lower, more stable energy level.

aalyn [17]

Answer:

<u>Oxygen</u>

Explanation:

If we had the same question then the table would've given the specific heat for these gases:

Water (steam) | 2.08

Air (25°C) | 1.01

Oxygen | 0.92

Hydrogen | 14.30

Out of these options, oxygen has the lowest specific heat and so it has the least heat-storing ability of the group.

Explain why mineral oil which is a mixture of hydrocarbons does not dissolve in water
Mkey [24]
Oil molecules like to stick to other oil molecules more than they like to stick to water molecules. This is because mineral oil has nonpolar molecules and water has polar ones.

6. The Earth’s electric field is directed vertically downward; at the ground level its strength is E = 130 N/C, and at an altitu
Alexxx [7]

Answer:

5.31x10⁻⁶ C

Explanation:

The cube is located 100 m altitude from the ground, so the superior face is at 100m and has E = 70 N/C, and the inferior face is at the ground with E = 130 N/C.

The electric field is perpendicular to the bottom and the top of the cube, so the total flux is the flux at the superior face plus the flux at the inferior face:

Фtotal = Ф100m + Фground

Where Ф = E*A*cos(α). α is the angle between the area vector and the field (180° at the topo and 0° at the bottom):

Фtotal = E100*A*cos(180°) + Eground*A*cos(0°)

Фtotal = 70A*(-1) + 130*A*1

Фtotal = 60A

By Gauss' Law, the flux is:

Фtotal = q/ε, where q is the charge, and ε is the permittivity constant in vacuum = 8.854x10⁻¹² C²/N.m²

A = 100mx100m = 10000 m²

q = 60*10000*8.854x10⁻¹²

q = 5.31x10⁻⁶ C
