The Sun radiates energy at a rate of about 4 × 1026 W.

1) At what distance from the Sun is its intensity the same as that of a 100 W light bulb 1 m away from you?

2) How does that compare to the distance between the Sun and the Earth?

3) Between which 2 planets’ orbits does this distance lie?

Expert Solution

P = 4 X 10²⁶ W

Intensity is defined as power per unit area

The intensity of the sun is equal to the intensity of bulb at 1 m distance

equating it to the intensity of the sun at a distance r

r = 2 X 10¹² m

2) the distance between the Sun and earth is d = 150 X 10⁹ m

r = 13.33 d

this distance is approximately 13 times more than the distance between Sun and Earth

3) The distance lies between Saturn and Uranus

The Earth-atmosphere system absorbs energy from the sun and radiates it back into space as black-body radiation. (a) Make an estimate for the overall average temperature of the Earth-atmosphere system. You must explain your reasoning in making this estimate. (b) Use you answer in (a) to determine the wavelength of the most plentiful black-body radiation from the system?

1. (a) What is the rate at which the Sun delivers energy to the entire Earth ? Assume that all of the incident energy is absorbed. (b) From the internet (or whatever information source handy), find out the total rate at which energy is used by humans per second, and compare with your estimate in Part (a). What area of solar panels would be required to provide all the power required by the Earth’s population ? (Assume the panels have...

1. A 100-watt lightbulb radiates energy at a rate of 100 J/s (The watt, a unit of power, or energy over time, is defined as 1 J/s). If all of the light emitted has a wavelength of 505nm, how many photons are emitted per second? (Assume three significant figures in this calculation.) 2.Calculate the de Broglie wavelength of a 143-g baseball traveling at 80 mph . 3.An electron undergoes a transition from an initial (ni) to a final (nf )...

1. Imagine that the energy generation rate in the center of the Sun were suddenly to decrease. How would the size of the core, and hence density, change in response to changes you described in your answer to the previous question? 2.How would the density change in the previous question in turn affect the energy generation rate and hence the temperature? 3. Put your answers to the three previous questions together to explain how the Sun maintains a perfect structural...

1. The Lifetime of the Sun. The total mass of the sun is about 2 x 1030 kg, of which about 75% was hydrogen when the sun formed. However, only about 13% of this hydrogen ever becomes available for fusion in the core. The rest remains in layers of the sun where the temperature is too low for fusion. a) Use the given data to calculate the total mass of hydrogen available for fusion over the lifetime of the...
