A husband buys a helium-filled anniversary balloon for his wife. The balloon has a volume of 3.0L in the warm store at 74?F. When he takes it outside, where the temperature is 46?F, he finds it has shrunk.
By how much has the volume decreased?

Question: Point charges q1 = +2.00 (mu)C and q2 = -2.00 (mu)C are placed at adjacent corners of a square for which the length of each side is 1.00 cm. Point a is at the center of the square, and point b is at the empty c ...
Question: A point charge with charge q_1 is held stationary at the origin. A second point charge with charge q_2 moves from the point (x1, 0) to the point (x2, y2). How much work W is done by the electrostatic force on t ...
In an attempt to skip a rock off the surface of a lake, you throw the rock from a height h=1.67 m above the lake surface with an initial speed of v0 = 6.85 m/s at an angle of θ=12.3° below the horizontal. How long until ...
Question: A sump pump (used to drain water from the basement of houses built below the water table) is draining a flooded basement at the rate of 0.55 L/s, with an output pressure of 2.9 Ã- 105 N/m2. a) The water enters ...
Question: A real image is four times as far from a lens as is the object. What is the object distance, measured in focal lengths? The response must be typed, single spaced, must be in times new roman font (size 12) and m ...
Question: At one point in a pipeline the water's speed is 3.00 m/s and the gauge pressure is 5.00 x 10 4 Pa. Find the gauge pressure at a second point in the line, 11.0 m lower than the first, if the pipe diameter at the ...
Qustion: A pendulum is made by tying a 590 g ball to a 45 cm-long string. The pendulum is pulled 22o to one side, then released. Part A: What is the ball's speed at the lowest point of its trajectory? Part B: To what ang ...
Question: In this problem we will consider a collision of two moving objects such that after the collision, the objects stick together and travel off as a single unit. The collision is therefore completely inelastic. You ...
Question: An old-fashioned LP record rotates at 33 1/3 rpm (revolutions per minute) and is 12 inches in diameter. A "single" rotates at 45 rpm and is 7.0 inches in diameter. If a fly sits on the edge of an LP and then on ...
Question: A parallel-plate capacitor is formed from two 1.5 cm -diameter electrodes spaced 2.1 mm apart. The electric field strength inside the capacitor is 1.0 Ã-10 6 N/C. What is the charge (in nC) on each electrode? ...
