The greenhouse effect is significant not only on Earth but also on Venus and Mars. The following table summarizes the following basic observations:
(A) Using Stefan's equation and the principle of loss of energy flux density as a function of distance from the Sun (T=5800oK), calculate the irradiance I at the top of the atmosphere of each of the three planets.
(B) The effective energy reaching the planetary surface should be the amount calculated in (a) divided by 4 (because only the planetary disk, the 2D surface ΠRplanet2) faces the Sun at any given time. Use Stefan's equation to calculate the energy that will be emitted by each of the three planets given the solar irradiances calculated in (a), and calculate their effective surface temperatures. Why don't the results agree with Column 2 in the above table? Explain a likely reason for the discrepancies, and compare the discrepancies among the planets.
2. Surface Crystallography and Epitaxy Fe thin films are grown on a single-crystal Al (100) substrate surface. The films grow with no dislocations (if they are thin enough) which
Resistance: Resistance is the opposition to the motion of electrons. This arises as a result of collision of moving electrons. The unit of resistance is "ohm" represented by
Red light (λ = 685 nm) falls on a slit that is 0.025 mm wide. The distance between the centers of the central bright band and the second-order dark band is 6.3 cm. What is
The equation of reflected wave for soft boundary: y(x.t)=A cos[(wt-kx)] The equation of reflected wave for rigid boundary: y(x.t)=A cos[(wt+kx)] where A=amplitude of the wave
Would a nail rust in oil and water or water and oxygen?
The effects of open circuits: An open circuit is essentially a break in the circuit. An open circuit in a series circuit will prevent the flow of current through the circuit. W

The characteristic of a body by virtue of which the body takes its real configuration when external deforming forces are removed is called as elasticity.
Astigmatism: In this defect the surface of eye is not perfectly spherical. The eye has different focal point in dissimilar planes and image of an object is not focused clearly
The fundamental particles: Although other atomic particles are known, the three fundamental ones are: Protons. The proton has unit mass and carries a unit positive charge.
