Classify the planets as inner planets of outer planets explain your answer​

Physics
1 answer:
rusak2 [61]3 years ago
7 0

Answer: Planets A and B have a rocky mantle and an iron core. They are at a distance of 1 AU or less from the Sun. This means they are relatively close to the Sun. There are the properties of inner (terrestrial) planets. So planet A and B are inner planets.

Explanation:

Planet C is composed if the gases hydrogen and helium. It has a high mass and is much farther from 1 AU from the sun. These properties are consistent with the outer planets. So, planet C is an outer (gas giant) planet.

Monochromatic light is incident on a grating that is 75 mm wide and ruled with 50,000 lines. The second-order maximum is seen at
notsponge [240]

Answer:

= 403 nm

Explanation:

We have the condition for the maximum for a diffraction grating

                                     d sinθ =mλ

Then the grating constant d = w/N

                                    = (75 mm)/(50,000)

                                      = 0.0015 mm

Then wavelength of light is λ = (dsinθ)/m

                                        = (0.0015 mm)(sin 32.5)/2

                                     =403*10-6 mm

                                        = 403 nm

A 14-Ω coffee maker and a 14-Ω frying pan are connected in series across a 120-V source of voltage. A 20-Ω bread maker is also c
Ann [662]

Answer:

The total current supplied by the source of voltage = 10.29 A

Explanation:

We have a 14-Ω coffee maker and a 14-Ω frying pan are connected in series.

Effective resistance = 14 + 14 = 28Ω

Now we have 28Ω and 20Ω in parallel

Effective resistance

             R=\frac{28\times 20}{28+20}=11.67\Omega

So we have resistor with 11.67Ω in a 120 V source of voltage.

We have equation V = IR

Substituting

               120 = I x 11.67

                 I = 10.29 A

The total current supplied by the source of voltage = 10.29 A
