Scientists plan to release a space probe that will enter the atmosphere of a gaseous planet. The temperature of the gaseous planet varies linearly with the height of the atmosphere. The delicate instruments on board completely fail at a height of 61.5 kilometers. What is the approximate temperature at this altitude? A. 200 K B. 250 K C. 300 K D. 400 K E. 450 K
A 0.200-kg block along a horizontal track has a speed of 1.80m/s at once before colliding with a light spring of force constant 44.2 N/m located at the end of the track.
A loudspeaker of mass 18.00 {rm kg} is suspended a distance of h = 1.20 {rm m} below the ceiling by two cables that make equal angles with the ceiling.
determine the mass of liquid ammonia that boils away before thermal equilibrium. Assume an excessive amount of liquid ammonia is present and that the liquid ammonia does not react with the copper.
