Q. A space station, in the form of a wheel 119 m in diameter, rotates to provide an "artificial gravity" of 3.80 m/s2 for persons who walk around on the inner wall of the outer rim. Find the rate of the wheel's rotation in revolutions per minute that will produce this effect.
Q. Suppose 12.0 g of oxygen (O2) gas is heated at constant atmospheric pressure from
(a) How many moles of oxygen are present? (See Table 19-1 in the book for the molar mass.)
(b) How much energy is transferred to the oxygen as heat? (The molecules rotate but do not oscillate.)
(c) What fraction of the heat is used to raise the internal energy of the oxygen?
What volume of water at 0°C can a freezer make into ice cubes in 1.4 hours, if the coefficient of performance of the cooling unit is 8.0 and the power input is 1 kilowatt.
From a cliff that is 9.4 m above a lake, a young woman (mass 44 kg) jumps from rest, straight down into the water. At the instant she strikes the water, what is her de Broglie wavelength.
Dan is gliding on his skateboard at 2m/s. He suddenly jumps backward off the skateboard, kicking the skateboard forward at 7.00m/s (as measured by an observer on the ground). Dan's mass is 50 kg and the skateboard's mass is 5.00 kg.
A professor's office door is 0.9 wide, 2.0 high, and 4 thick; has a mass of 25; and pivots on frictionless hinges. A "door closer" is attached to door and top of the door frame.
A good model for a radio antenna is a dipole. P1 is on the perpendicular bisector of the dipole, and P2 is along the axis of the dipole in the direction of dipole vector ˆp. P1 and P2 are both a distance 100m from the center of the dipole.
A capacitor is connected across the terminals of an ac generator that has a frequency of 370 Hz and supplies a voltage of 15 V. When a second capacitor is connected in parallel with the first one, the current from the generator increases by 0.27 A. D..
A 50 g ball is fired horizontally with initial speed v_0 toward a 110g ball that is hanging motionless from a 1.10 m-long string. The balls undergo a head-on, perfectly elastic collision, after which the 110g ball swings out to a maximum angle the..
