The indices of refraction for violet light (? = 400 nm) and red light (? = 700 nm) in diamond are 2.46 and 2.41, respectively. A ray of light traveling through air strikes the diamond surface at an angle of 53.5? to the normal. Calculate the angular separation between these two colors of light in the refracted ray.
A force with a magnitude of 452N is used to bring an object with a mass of 56.0 kg moving at a velocity of 155m/s. How long will it take to bring the object to a full stop.
A bar magnet is oriented with its magnetic dipole moment at 39.5° to the direction of a 0.0689-T magnetic field, causing a torque of 0.00351 N·m to act on it
A wave on a string is described by the equation y = (4.2 mm)cos(3000t 0.45x) where t is measured in s and x is measured in mm
Find out h orizontal angle of projectile
A double-slit experiment is set up using red light (l = 714 nm). A first order bright fringe is seen at a given location on a screen. What wavelength of visible light (between 380 nm and 750 nm) would generate a dark fringe at the identical locati..
A swimmer heads directly across a river, swimming at 1.60 m/s relative to the water. She arrives at a point 58.0 m downstream from the point directly across river, 63 m wide. What is the speed of the river current.
A 1.00 kg glider on a horizontal air track is pulled by a string at an angle θ. The taut string runs over a pulley and is attached to a hanging object of mass 0.500 kg .
A 5 uF capacitor is initially charged to a potential of 16 V. It is then connected in series with a 3.75 mH inductor.
A ball is thrown in the air at an initial angle 35 degrees above the horizontal. It takes 4 seconds for the ball to hit the ground
A physics student standing on level ground finds that an imaginary line drawn from his eye to the top of a tree, If his eyes are 5.8 feet above ground, what is the height of the tree
Regarding the Earth and a cloud layer 750 m above the Earth as the "plates" of a capacitor, calculate the capacitance. Assume the cloud layer has an area of 1 km2 and that the air between cloud and ground is pure and dry.
A 10.0g bullet is fired horizontally into a 101g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring having spring constant 141 N/m. The bullet becomes embedded in the block. If bullet-block system co..
