A tank holds a layer of oil, of thickness To = 1.43 m, that floats on a layer of syrup of thickness Ts = 0.640 m, as shown in the figure. Both liquids are clear and do not mix together. A light ray, originating at the bottom of the tank at point P, crosses the oil-syrup interface at a point 0.900 m from the axis. The ray continues and arrives at the oil-air interface, 2.00 m to the right of P and at the critical angle. What is the index of refraction of the oil?
You travel to an alien planet. The local population tries very hard to tell you what gravity is on the surface. You cannot understand them, and do not have a tool to calculate gravity directly. You also ran out of water. They offer a liquid to you, o..
The spacecraft's mass is 291 kg and the thrust (force) of the rocket engines is 59 N. If the speed of the spacecraft should be decreased by 128 m/s, how long the engines should be fired. (Ignore the change in mass as a result of the rocket engines..
The rotor of a toy gyroscope consists of an annular cylinder attached to cylindrical shafts by spokes. The rotor is spun by pulling on a string wrapped around shaft.
From the shape of total energy vs. time plot, what can you conclude about the conservation of mechanical energy in your mass and spring system.
two vehicles of equal mass at a 90 degree intersection. If the momentum of vehicle A is 1.20 x 10^5 kg km/h east and the momentum of vehicle is 8.50 x 10^4 kg km/h north, what is the resulting momentum of the final mass
On a workday the average decibel level of a busy street is 80 dB, with 100 cars passing a given point every minute. If the number of cars is reduced to 45 every minute on a weekend, what is the decibel level of the street.
A logic circuit has two 2-bit unsigned binary numbers X[1:0] and Y[1:0] as the inputs and it has two 1-bit outputs. One of the outputs is ONE_GTR and the other is X1_XOR_Y1.
Billy is running on level ground with a speed of 3.5 m/s. He attempts to jump a ditch that is 1.5 meters wide. if the horizontal component of his velocity does not chance.
Starting from rest, the elevator accelerates upward. During the acceleration, the hoisting cable applies a force of 9300 N. Illustrate what does the scale read during the acceleration?
A cylinder is rolling along the ground without the slipping at 7m/s. It comes to a hill and begins going up. Assume no losses to friction, how high vertically would it go before it stops?
What is the terminal speed for a 76.0 skier going down a 41.0 snow-covered slope on wooden skis = 0.070? Suppose that the skier is 1.80 m tall and 0.500 m wide. Replace mg with net forces parallel to the incline.
