Question

This question carries 15 points

Please download the Excel file. It has GRACE-GRACE/FO water level change data for the

UAE. Please find the linear regression model for this data, interpret the equation, and

finally calculate the total water level decline for the UAE using the linear regression model.

Each question below carries 10 points

1. Please explain how you can calculate the wavelength associated with 2500K, 4000K,

and 6900 K temperatures. And what information can you extract from it related to

the frequency of the wave at each temperature?

2.

By using (0 << 1) can you identify what type of emitter it is, and please explain

how you identified it?

3. During the barbecue, you noticed different temperatures: 100 °C, 125 °C, 150 °C, and

200° C. Please explain how you determined the number of radiations emitted by coal

at each temperature.

4. The star constant of a star is 6.765 x 1030 W and a planet is located at a distance of

7x10¹3 meters. Please calculate the intensity of radiation received by the planet.

Each question below carries 5 points

1. Please explain what happens to the intensity of radiations with the changing

distance.

2. Please explain the different modes of energy transfer and what happens to the

particles of the medium when they are transferring energy.

3. Please explain how the electric and magnetic components oscillate in

electromagnetic waves.

4. Please differentiate between perihelion and aphelion.

5. Please explain how seasons are formed on our planet.

6. Please explain how different pressure belts are formed on our earth.

7. Please explain what causes the change in day length at different times of the year.

8. Please explain what causes the Coriolis Force.

9. Please explain why the sky is blue during normal days and appears reddish,

especially at sunrise and sunset and on polluted days.
