05.1 You are designing a banked turn at an automobile racetrack. There are two requirements:
1.) Cars that come to a stop are to not slide down the banking, and
2.) for safety reasons, the maximum speed in the turn without spinning out should be 150 mi/hr. The coefficient of static friction between the track and the tires is 0.400. What are the radius of curvature R and banking angle ? with respect to the horizontal that satisfy these requirements?
A quantity of heat is removed from a hot reservoir at absolute temperature T and then is added to a cold reservoir at absolute temperature T/2. The cold reservoir experiences an entropy increase S. What is the change in the entropy of the universe..

An object weighs 294N in the air. When tied to a string, connected to a balance, and immersed in water, it weighs 240N. When it is immersed in oil, it weighs 258N.
A fan at a rock concert is 35m from the stage, where sound intensity level is 125 dB. Her eardrums have a diameter of 8.07mm. How much energy is transferred to each eardrum in one second? (Distance from the speaker to the edge of the stage is 1 m...
Electric bees. As they fly through the air, honeybees can pick up a small amount of electric charge, Find the magnitude of the electric force on the bee in the electric field just above Earth's surface, 130N/C directed vertically downward
what happens to light of a particular frequency when it is incident upon the material that natural frequency is the same as the frequency of the light.
Two carts with masses of 4.80 kg and 2.78 kg move toward each other on a frictionless track with speeds of 4.94m/s and 3.17m/s respectively. The carts stick together after colliding head-on. Find out the final speed.
