A Jaguar XK8 convertible has an eight-cylinder engine. At the beginning of its compression stroke, one of the cylinders contains 491cm3 of air at atmospheric pressure (1.01

You've packed a cube shaped cooler for the beach. Its 6 walls are made of 2 centimeter thick styrofoam and have lengths and heights of 40 centimeters each. If you were to fill it with 0 degree ice, how much ice would melt in 2.6 hours if the cooler was sitting in +35 C warm air. (use 0.035 for the k value of styrofoam and 334000 J/kg for the latent heat of fusion for ice.)

1. A mirror of focal length 22.4 cm creates an image with magnification -0.350. What is the image distance?

2. As light travels between media with different indices of refraction, which of the following wave properties changes: speed, frequency, wavelength?

Four two-dimensional objects are shown below, with a square grid drawn for reference. Each white square is empty, while each green square contains uniformly dense mass. For each object, choose the row (1-4) and column (a-d) in which the object\'s center of mass is located.

The cable lifting an elevator is wrapped around a

1.2-m-diameter cylinder that is turned by the elevator's motor. The elevator is moving upward at a speed of 2.6 m/s . It then slows to a stop, while the cylinder turns one complete revolution.

How long does it take for the elevator to stop?

a)At a distance of 0.216cm from the center of a charged conducting sphere with radius 0.100cm, the electric field is 440N/C . What is the electric field 0.604cm from the center of the sphere?

b)At a distance of 0.216cm from the axis of a very long charged conducting cylinder with radius 0.100cm, the electric field is 440N/C . What is the electric field 0.608cm from the axis of the cylinder?

c)At a distance of 0.180cm from a large uniform sheet of charge, the electric field is 440N/C . What is the electric field 1.23cm from the sheet?

I am a physics undergrad and thinking of exploring quantum information theory. I had a look at some books in my college library. What area in QIT, is the most mathematically challenging and rigorous? From what I saw in the books, most topics was just simple linear algebra. I am looking for an area which is mathematically more rich, and uses maybe more concepts from theoretical computer science, number theory, discrete maths, algebra etc. Classical cryptography is an area on the interface of maths and TCS which uses many areas of maths such as number theory, algebra, ellptical curves. Is the quantum cryptography also rich in mathematics? What are the prerequisites? If not, please could you suggest some areas that I are mathematically rich in QIT?

Four masses are at the corners of a square whose side is 2m long. (500kg top left, 300kg top right, 100kg bottom left, 500kg bottom right) Find the magnitude and direction of the net gravitational force on Ma(100kg) which is in the center of the square. (G=6.67*10^-11)

A ball is launched straight up into the air with an initial velocity=40m/s.

a) How much time does it take for the ball to reach its maximum height?

b) What is the maximum hieght that the ball reached above the launch point?

c) Calculate the total time the ball spends in the air until it returns to the same height that it was launched from.

d) What is the acceleration of the ball as it is rising to its maximum height?

block 1 of mass m1 slides from rest along a frictionless ramp from height h = 3 m and then collides with stationary block 2, which has mass m2 = 5m1. After the collision, block 2 slides into a region where the coefficient of kinetic friction μk is 0.1 and comes to a stop in distance d within that region. What is the value of distance d if the collision is (a) elastic and (b) completely inelastic?

An ion can produce an emission spectrum according to the Bohr model. A group of lines in the spectrum forms a series with wavelength between 10.13 nm and 18.23 nm. What is the shortest wavelength in the next series from the same ion?

______ nm

A bullet with mass m = 0.1 kg grams hits a ballistic pendulum with length L = 3 meters and mass M = 2 kg and lodges in it. When the bullet hits the pendulum it swings up from the equilibrium position and reaches an angle 15 degrees at its maximum. In this problem, you will determine the bullet’s velocity. First, I want to ask you a couple of questions:

1. While the bullet is embedding into the block, is energy conserved? Why or why not?

B.While the bullet is embedding into the block, is momentum conserved? Why or why not?

C. When the pendulum swings up to its maximum angle, is energy conserved? Why or why not?

D.When the pendulum swings up to its maximum angle, is momentum conserved? Why or why not?

E. Find the velocity of the bullet.

A glass flask whose volume is 1000cm3 at a temperature of 1.00?C is completely filled with mercury at the same temperature. When the flask and mercury are warmed together to a temperature of 52.0?C , a volume of 8.35cm3 of mercury overflows the flask. If the coefficient of volume expansion of mercury is ?Hg = 1.80
