A parallel beam of light containing red (660 nm) and blue (470 nm) wavelengths goes from polystyrene to water, striking the surface between them at a 48° incident angle. What is the angle between the two colors in water?
A mass m1 = 3.8 kg rests on a frictionless table and connected by a massless string over a massless pulley to another mass m2 = 5.5 kg which hangs freely from the string, What is the tension in the string as the block falls
Two charges q1 = 1.1 10-8 C and q2 = -4.8q1 are placed 50 cm apart. Find the point along the straight line passing by the two charges at which the electric field is zero, as measured from q1.
An air-filled pipe is found to have successive harmonics at 1050Hz , 1350Hz , and 1650Hz, It is an open-closed pipe, so What is the length of the pipe
The spring is then released. If the mass is attached to the spring, explain how far up the slope will the mass move before coming to rest? Express your answer using two significant figures.
Engineers can determine properties of a structure that is modeled as damped spring oscillator-such as a bridge-by applying a driving force to it, What is the oscillator\'s damping constant? (kg/s)
You are riding on a Jet Ski at some angle upstream on a river flowing with a speed of 2.8. Assume the Jet Ski is moving at a speed of 12 relative to the water. At what angle should you point the Jet Ski if your velocity relative to the ground is t..
A digital camera has 10 megapixels and each pixel has a depth of 32 bits. In units of megabytes calculate how much storage is needed for one image
A stone is thrown directly upward at 15.0 from ground level and feels no appreciable air resistance. make Use of the work-energy theorem to find how high it will be when its speed has been reduced to half of its initial value.
A sailboat is heading directly north at a speed of 21 knots (1 knot = 0.514 m/s). The wind is blowing towards the east with a speed of 10.6 knots. (Both velocities are given relative to the Earth.)
An object of mass 5 kg is moving with a momentum of 50 kg m/s. What is the objects speed? What is the objects kinetic energy
A 94 g piece of ice at 0.0°C is placed in an insulated calorimeter of negligible heat capacity containing 100 g of water at 100°C, What is the final temperature of the water once thermal equilibrium is established
