Two plane mirrors are facing each other. They are parallel, d = 8 cm apart, and l = 18 cm in length, as the drawing indicates. A laser beam is directed at the top mirror from the left edge of the bottom mirror. What is the smallest angle of incidence with respect to the top […]
Two particles are executing simple harmonic motion with same amplitude and frequency about the same equilibrium position. They pass each other moving in opposite direction, each time their displacement is half their amplitude. What is the difference between their phase constants, Δϕ? (Let 0 ≤ Δϕ ≤ π.)
Consider a particle in a one-dimensional box of length L in its lowest energy (ground)stationary state. Calculate the probability that the particle isa) in the left half of the boxb) in the middle third of the box.c) Draw a picture of the wavefunction and associated probability for each of parts a) andb) and explain your […]
A truck of mass mT = 2000 kg is going northon Guadalupe with a speed of 4 m/s. Thetruck is struck by an eastbound car (mass of1000 kg) traveling on 24th street. From theskidmarks after the collision, it is deducedthat the mangled wreckage, which sticks to-gether after the collision was skidding at angle20◦ with respect […]
how many grams of NaCL would you add to 500 ml of water to create a 1.75M solution of NACL
You’re driving down the highway late one night at 19 when a deer steps onto the road 40 in front of you. Your reaction time before stepping on the brakes is 0.50 , and the maximum deceleration of your car is 11. How much distance is between you and the deer when you come to […]
Spiny species of diatoms are found in both warm subtropical and cool waters. Since warm water is less dense then cold water, would you predict any difference between spines of warm water individuals and those of cold water individuals? Why?
This milestone will allow you to apply your newly acquired knowledge about clouds and precipitation.
