Q. Two sound sources radiating in phase at a fre- quency of 540 Hz interfere such that maxima are heard at angles of 0? and 21? from a line perpendicular to that joining the two sources. Find the separation between the two sources. The velocity of sound is 340 m/s. Answer in units of m.
Q. A communications satellite is in an orbit that is 3.10 107 m directly above the equator. Consider the moment when the satellite is located midway between Quito, Equador, and Belem, Brazil; two cities almost on the equator that are separated by a distance of 3.60 x10^6 m. Find the time it takes for a telephone call to go by the way of satellite between these cities. Ignore the curvature of the earth.
Take the mass of the sun to be m_s = 1.99×1030 {rm kg}, gravitational constant to be G = 6.67×10-11 {rm N} cdot {rm m^2/kg^2}, and an acceleration due to gravity at the earth's surface to be g = 9.810 {rm m/s^2}.

A 110 kg mail bag hangs by a vertical rope 4.0 m long. A postal worker then displaces the bag to a position 2.0 m sideways from its original position, always keeping the rope taut. As the bag is moved to this position, how much work is completed by t..
A 12 kg weather rocket generates a thrust of 250 N. The rocket, pointing upward, is clamped to the top of a vertical spring. The bottom of the spring, whose spring constant is 560 N/m, is anchored to the ground. What is the rocket's speed while the s..
A real object is placed at the zero end of a meterstick. A large concave mirror at the 100 cm end of the meterstick forms an image of the object at the 70.0cm position. A small convex mirror placed at the 20 cm position forms a final image at the ..
At a waterpark, sleds with riders are sent along a slippery,horizontal surface by release of a large, compressed spring.The spring with a force constant k= 3700 N/m and negligible mass rests on the frictionless horizontal surface.
Calculate the period T and the tension in the string F as a function of the angle. Compute the moment of inertia of this system for an axis that passes through the combined center of mass and is perpendicular to the plane of the rings.
