List the major satellites of Jupiter & Saturn. Briefly indicate some of their properties &/or why they are of particular interest

Two particles collide with a normal direction defined: 0.2i+0.98j (eT=0.98i+-0.2j). The first mass has a mass of 4 kg and a velocity of 4i m/s. The second mass has a mass of 4 kg and a velocity of -4i+2j m/s. The collision has a coefficient of restitution of 0.5.

Determine the tangential velocity of the second particle after the impact [m/s].

Determine the velocity in the normal direction of the second particle after the impact [m/s]. (e_N w.r.t. the collision framework, not the kinematic reference frame system)

Determine the velocity in the j-direction of the second particle after the impact [m/s].

Explain the mechanism that creates the hyperfine structure of hydrogen.

The table below list heights (in m) and temperatures (in °C) at 18 UTC on February 16, 2009 for several pressure levels at San Diego, CA. The data were derived from a computer simulation of the atmosphere. Although thunderstorms are relatively infrequent along the southern California Coast, there is a tendency for more thunderstorms during winter. This image is the 18 UTC radar from San Diego on February 16, 2009 (the white square shows the radar’s location).

1. Compute the environmental lapse rate for the 1000-925 mb layer, the 925-850 mb layer, the 850-700 mb layer, and the 700-600 mb layer. Express your answers in °C/km.
2. Which layers are stable? Which layers are conditionally unstable? How did you make your decisions?

Make a table listing some of the major similarities & differences between Jupiter & Saturn. (Include such characteristics as: orbital & rotational properties; structure & composition of interiors & atmospheres; internal heat sources & magnetic fields; etc.)

explain consideration of earth's rotation in designing and launching missiles and also explain angular velocity vector.

explain fiber optic methods of pressure sensing, piezoelectric, magnetostrictive and hall-effect sensors, smoke and fire detectors.

Briefly explain how the shape of the BE distribution function solves the UV catastrophe.

Search for Extraterrestrial Intelligence (SETI) up to this point the search for extra terrestrial intelligence has come up empty. The reasons why we have not observed other life is up for debate and the subject of the Fermi Paradox. A thought experiment centering on the existence of alien life is summarized by the: Drake Equation

? = ?? ∙ ?? ∙ ?? ∙ ?? ∙ ?? ∙ ?? ∙ ?

N – number of civilizations in our galaxy with which communication might be possible

Rs - average rate of star formation per year

fp - fraction of formed stars that have planets

ne - for stars with planets, average number of planets that can support life

fl - fraction of those planets that actually develop life

fi - fraction of planets bearing life on which intelligent, civilized life, has developed

fc - fraction of these civilizations that developed communications

L - length of time over which civilizations release detectable signals

The equation works its way through some of the necessary conditions for humans to contact alien life. Some values such as Rs are relatively understood for our galaxy, while others further down the list cannot be. For the bonus assignment, solve the Drake Equation by coming up with values for each term in the equation with a sentence or two explanation for your estimate. There are no hard and fast, right or wrong answers, just give some idea or thought behind the values you come up with.

What is your value for the number of civilizations in our galaxy we might communicate with?

A long, straight wire carrying a current of 3.00 A moves with a constant speed v to the right. A 5-turn circular coil of diameter 1.25 cm, and resistance of 3.25 µΩ, lies stationary in the same plane as the straight wire. At some initial time, the wire is at a distance

d = 19.5 cm

from the center of the coil. 4.55 s later, the wire is at a distance 2d from the center of the coil. What is the magnitude and direction of the average induced current in the coil? Note that while the magnetic field varies over the diameter of the coil, it is very small and we will disregard this variation.

A helium balloon ride lifts up passengers in a basket. Assume the density of air is 1.28 kg/m³ and the density of helium in the balloon is 0.18 kg/m³. The radius of the balloon (when filled) is R = 4.5 m. The total mass of the empty balloon and basket is m_b = 123 kg and the total volume is V_b = 0.068 m³. Assume the average person that gets into the balloon has a mass m_p = 74 kg and volume V_p = 0.077 m³.

Why is chromatic Aberration a problem for astronomers and not for thin lens?

⦁   Use the equation of motion to show that once released from submersion the magnitude of the acceleration a, for the object that ascends (floating to the surface), in terms of the density of the fluid and object is:

a = (ρoil /ρo – 1)g

⦁   Use one of the previous equations to determine the density of the oil?

Cuando se coloca un material dieléctrico entre las placas de un capacitor, su campo eléctrico resulta disminuido en el valor de la constante dieléctrica del material. La razón física de esto es:

a) las placas del capacitor pierden carga

b) el material dieléctrico impide que pase campo

c) el material dieléctrico se vuelve conductor

d) el campo eléctrico induce un campo en el material que se opone al campo original

e) ninguna de las anteriores
