A particle with mass 1.81 x 10^-3 kg and a charge of 1.22 x 10^-8 C has an initial velocity of vector v = (3.00 x 10^4 m/s)hj^. If the particle enters a magnetic field give by vector B = (1 .63T)i^ + (0.980T)j^, determine the particle's acceleration.
A 3.0x10 ² kg piano is being lifted at a steady speed from ground level straight up to an apartment 10 m above the ground. How much time does it take to lift the piano
What is the acceleration of the crate? What is the work done by gravity? What is the work done by friction? What is the kinetic energy at the bottom?
a lead ball is dropped into a lake from a diving board 18 ft. above the water. it hits the water with a certain
A diffraction grating produces a first-order maximum at an angle of 25.0 degree. What is the angle of the second-order maximum
Speedboat A negotiates a curve whose radius is 118 m. Speedboat B negotiates a curve whose radius is 270 m. Each boat experiences the equivalent centripetal acceleration. What is the ratio vA/vB of the speeds of boats.
A 15 cm focal length converging lens is used to magnify small newspaper print 2 mm high. Compute the height of the image for the maximum angular magnification for a normal eye. Suppose the eye focuses at the near point of 25 cm.
Heat Q flows spontaneously from a reservoir at 445 K into a reservoir at 265 K. Because of the spontaneous flow, 2620 J of energy is rendered unavailable for work when a Carnot engine operates between the reservoir at 265 K and a reservoir at 248 K. ..
Model the electromagnetic wave in a microwave oven as a plane traveling wave moving to the left, with an intensity of 26.3 kW/m2. An oven contains two cubical containers of small mass, each full of water.
A 13.00 g bullet travelling 236 m/s penetrates a 2 kg block of wood and emerges cleanly at 179 m/s. If the block is stationary on a frictionless surface as hit, how fast does it move after the bullet emerges.
During a tennis match, a player serves the ball at a speeds, with the center of the ball leaving the racquet atangle θ below the horizontal at a heighty0. The net is a distance d away andhas a height h. When the ball is directly over the net,what ..
