Q. A new experiment is created with the screen at a distance of 2 m from the slits (with spacing 0.08 mm). What is the distance between the second order bright fringe of light with l = 690 nm and the third order bright fringe of light with l = 404 nm? (Give the absolute value of the smallest possible distance between these two fringes: the distance between bright fringes on the same side of the central bright fringe.)
Q. A cockroach of mass m lies on the rim of a uniform disk of mass 8.00 m that can rotate freely about its center like a merry-go-round. Initially the cockroach and disk rotate together with an angular velocity of 0.200 rad/s. Then the cockroach walks half way to the center of the disk.
(a) What then is the angular velocity of the cockroach-disk system?
(b) What is the ratio K/K0 of the new kinetic energy of the system to its initial kinetic energy?
As part of a safety investigation, two 1200 {rm kg} cars traveling at 24 {rm m/s} are crashed into different barriers. Find the average forces exerted on (a) car that hits a line of water barrels and takes 1.80 {rm s} to stop, and (b) car that hits a..
What was the average acceleration throughout the trip
A certain car is capable of accelerating at a rate of 0.52 m/s2. How long does it take for this car to go from a speed of 27 mi/h to the speed of 33mi/h.
A cube of ice is taken from the freezer at -8.0°C and placed in a 97 g aluminium calorimeter filled with 286 g of water at room temperature of 20°C. The final situation is observed to be all water at 19°C. What was the mass of the ice cube.
A child of mass 24 kg sits 2.10m to the left of the center of a seesaw. The mass of the seesaw is 35 kg. How far to the right of the central pivot must a second child of mass 40 kg sit if the seesaw is to be perfectly balanced.
A person is making homemade ice cream. She exerts a force of magnitude 22 N on the free end of the crank handle, and this end moves in a circular path of radius 0.28 m. The force is always applied parallel to the motion of the handle. If the handl..
The pilot of an aircraft wishes to fly due west in a 34.60 km/h wind blowing toward the south. The speed of the aircraft in absence of a wind is 145 km/h.
What is the flux of Zn moving down the rod? Write down all your assumptions (hint: you will need to look up the density of copper. You do not need to account for the variation in density with alloy composition). Clarify what the boundary conditions w..
A horse races once around a circular track in a time of 118s, with a speed of 17 m/s. What is the radius of the track? How do you go about solving this.
Compute magnitude of the average velocity
The position of a cart that is oscillating on a spring is given by the equation x= 12.3 cm cos [(1.26 s-1)t] . When t= .805s , what are the (a) velocity and (b) acceleration of the cart ?
Mary is driving her car at 48 km/h. She approaches an intersection just as the traffic light turns yellow. The yellow light lasts only 3.0 s before turning to red, and she is 30 m away from the near side of the intersection.
