Q. What is the smallest thickness of a soap film (n = 1.33) that would appear black if illuminated with 450 -nm light? Assume there is air on both sides of the soap film.
Q. An initially stationary block of mass m is on the floor. A force of magnitude 0.500mg is then applied at upward angle θ = 20°. What is the magnitude of the acceleration of the block across the floor if (a)μs = 0.600 and μk = 0.510 and (b)μs = 0.400 and μk = 0.340?
An insulated Thermos contains 210 cm3 of hot coffee at 88 °C. You put a 19.00 g ice cube at its melting point to cool the coffee. By how many degrees has the coffee cooled once the ice has melted and equilibrium is reached? Treat the coffee as though..
Two 53 {rm g} blocks are held 30 {rm cm} above a table. One of them is just touching a 50-long spring. The blocks are released at the same time. The block on the left hits the table at accurately the same instant as the block on the right first comes..
Using the equation F=m v^2/r for a force an object in circular motion. Find the radius r of motion of a m=1.6 kg ball travelling in a circular path acted upon by a centripetal force F=7N.
A 23 bullet traveling 240 penetrates a 4 block of wood and emerges going 170. If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges.
A basketball player grabbing a rebound jumps 73.3 cm vertically. How much total time (ascent and descent) does the player spend (a) in the top 13.1 cm of this jump and (b) in the bottom 13.1 cm? Do your results explain why such players seem to han..
Scientist calls a theory that unites many ideas in a simple way "beautiful." Are unity and simplicity among the criteria of beauty outside of science? Help support the answer.
A very long solenoid with a circular cross section and radius r= 8.1cm with n= 1.90E+4 turns/m has a magnetic energy density uB= 5.70 mJ/m3. What is the current in solenoid.
A bolt is dropped from a bridge under construction, falling 92m to the valley below the bridge. (a) How much time does it take to pass through the last 26 percent of its fall? What is its speed (b) when it begins that last 26 percent of its fall a..
