You are standing on the edge of a swimming pool and looking directly across at the opposite side. you notice that the bottom edge of the opposite side of the pool appears to be at an angle of 26.9° below the horizontal. however, when you sit on the pool edge, the bottom edge of the opposite side of the pool appears to be at an angle of only 14.1° below the horizontal. use these observations to determine the width and depth of the pool. hint: you will need to estimate the height of your eyes above the surface of the water when standing and sitting. (assume 1.7 m when standing and 0.7 m when sitting.)

Abatter hits the baseball a with an initial velocity of v0 = 110 ft/sec directly toward fielder b at an angle of 23° to the horizontal; the initial position of the ball is 2.2 ft above ground level. fielder b requires 0.44 sec to judge where the ball should be caught and begins moving to that position with constant speed. because of great experience, fielder b chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. the catch position is the field location at which the ball altitude is 8.4 ft. determine the velocity of the ball relative to the fielder at the instant the catch is made.

How does the space charge width change with forward and reverse bias? also, calculate the space charge width for a reverse bias of 4v on a silicon pn junction at t = 300k and doping concentrations of na = 5x1015cm-3 , nd = 5x 1016 cm-3 .

Porque crees que el agua no podia subir mas de 10 m de altura con ese tipo de bomba
