33. 2075 set a q. no. 102 the sun is a black body of surface
temperature about 6000k. if sun's radius is 7x108m.
calculate the energy per second radiated from its surface.
the earth is about 1.5x1011 m from the sun. assuming all
the radiation from the sun falls on the surface of sphere of
this radius, estimate the energy per second per meter?

The car hoist allows the car to be driven onto the platform, after which the rear wheels are raised. if the loading from both rear wheels is 1380 lb, determine the force in the hydraulic cylinder ab. neglect the weight of the platform itself. member bcd is a right-angle bell crank pinned to the ramp at c. the force is positive if in tension, negative if in compression.

The experiment was repeated many years later but the gases were mixed in a different type of container. a white solid was obtained which was xenon fluoride. predict whether you think 1) krypton and 2) radon will react with fluorine. explain reasons for your predictions
