A beam of unpolarized light of intensity 12.o w/m^2 is incident on an ideal linear polarizer, P1, whose transmission axis is in the vertical (y) direction. The light then moves to a second ideal polarizer, P2, whose axis of transmission is at 37 degrees from the vertical.
A. What is the intensity of light emerging from P1?
B. What is the intensity of light emerging from P2 ?
C. If the light were to then go through a third ideal polarizer, P3, at what angle from the vertical should the transmission axis of P3 be oriented such that the light transmitted from P3 is one-tenth the intensity of the incident unpolarized light?
Find the work done by this force on the particle and the final speed of the particle as it moves along a path.
A father and a daughter balance a teeter totter
when it falls back it hits the ground with speed v1=50m/s. The mass of the ball is m=20g. Evaluate what is the total work done by the drag force while the ball is in the air?
Pitman Co's tax rate is 40% for 2013 an all future years. At the end of 2013, the following deferred tax account and balance that should be reported on Pitman's balance sheet is?
Far in space, where gravity is negligible, a 485kg rocket traveling at 95.0m/s fires its engines. It shows the thrust force as a function of time. The mass lost by the rocket during these 30 s is negligible.
A charge of -2.85 µC is fixed at the center of a compass. Two additional charges are fixed on the circle of the compass, which has a radius of 0.105 m. The charges on the circle are -3.8 µC at the position due north and +4.55 µC at the position du..
Charge q is fired through a small hole in the positive plate of a capacitor. If q is a positive charge, does it speed up or slow down inside the capacitor? reply this question using the concept of force.
A car travelling 92 {rm km/h} is 150 {rm m} behind a truck travelling 80 {rm km/h}. How long will it take the car to catch the truck.
A space vehicle is coasting at a constant velocity of 23.5 m/s in the +y direction relative to a space station. The pilot of the vehicle fires a RCS (reaction control system) thruster, which causes it to accelerate at 0.395 m/s2 in the +x directio..
Suppose an initial speed of 21.4 m/s, at an angle of 61.10° with respect to the positive x axis. Find the velocity at time t0; enter x component, after that the y component.
Calculate g for space shuttle territory. A 7.0×10-2-{rm kg} toy airplane is tied to the ceiling with a string. When the airplane's motor is started, it moves with the constant speed of 1.30 m/s in a horizontal circle of radius 0.47 m.
