Question 1. A person looking in to an empty container is able to see the far edge of the container’s bottom as shown. The height of the container is h, & its width is d. When the container is fully filled with a fluid of index of reflection n, the person can see a coin at the middle of the container’s bottom. Show that h/d is given by,
Question 2. A light beam is incident on a piece of fused quartz (n = 1.458) at the Brewster’s angle. Determine the value of the Brewster’s angle & the angle of refraction for the transmitted ray.
After the NEAR spacecraft passed Mathilde, on some occasion's rocket propellant was expelled to adjust the spacecraft's momentum in order to follow a path that would approach the asteroid Eros, final destination for the mission.
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..
In order to clearly read a book 24 cm away, a farsighted girl needs an image to be 35 cm from her eyes. What focal length is necessary for lens in her eyeglasses.
A 18.0 kg block is dragged over a rough, horizontal surface by a constant force of 77.6 N acting at an angle of 35? above the horizontal. The block is displaced 10.8 m, and the coefficient of kinetic friction is 0.149.
A magnifier has a magnification of 8 times. How far from the lens should an object be placed so that its (virtual) image is at the near-point distance of 25 {rm cm}.
Find the Youngs modulus for the muscle tissue
A force vector points at an angle of 50.6° above the +x axis. It has a y component of +280 newtons. Calculate the magnitude of the force vector.
A rifle with a barrel length of 56 cm fires a 14 g bullet with a horizontal speed of 350 m/s/s. The bullet strikes a block of wood and penetrates to a depth of 13 cm.
What is the velocity of observer B relative to observer A . A diver shines a light up to surface of a flat glass-bottomed boat at an angle of 36 relative to the normal.
Car A uses tires for which the coefficient of static friction is 1.1 on a particular unbanked curve. The maximum speed at which the car can negotiate this curve is 25 m/s. Car B uses tires for which the coefficient of static friction is 0.65 on the s..
