A small source of light Sis located at a distance Lfrom a vertical wall. An opaque object with a height of h moves toward the wall with constant velocityv_vec of magnitude v. At time t= 0 , the object is located at the source S. Find an expression for v_s, the magnitude of the velocity v_s_vec of the top of the object's shadow, at time t.

Express the speed of the top of theobject's shadow in terms of t, v,L, and h.

On a hot saturday morning while people are working inside, the air conditioner keeps the temperature inside the building at 22degreesc. at noon the air conditioner is turned off, and the people go home. the temperature outside is a constant 33degreesc for the rest of the afternoon. if the time constant for the building is 4 hr, what will be the temperature inside the building at 4 : 00 font size decreased by 2 upper p . font size decreased by 2 upper m .? at 6 : 00 font size decreased by 2 upper p . font size decreased by 2 upper m .? when will the temperature inside the building reach 24degreesc? 324281
