1.39 Chessboard **
An infinite chessboard with squares of side shas a charge eat the center of every white square and a charge -eat the center of every black square. We are interested in the work Wrequired to transport one charge from its position on the board to an infinite distance from the board. Given that Wis finite (which is plausible but not so easy to prove), do you think it is positive or negative?
A ball of mass 0.60 kg is fired with velocity 140 m/s into the barrel of a spring gun of mass 2.5 kg initially at rest on a frictionless surface. The ball sticks in the barrel at the point of maximum compression of the spring.
charge q1=1 ?C is located at the position (x,y,)=(5 cm, 7 cm). A second charge, q2=2 ?C is located at the position (x,y,)=(5 cm, 0 cm). Calculate the work required to move a third charge
The atomic mass of copper is 64 g/mole, and the density of copper is 8.9 g/cm3.
A golfer swings his club of radius 1.2 m at an angular velocity (w) of 340º/s. What is the linear velocity of the club head? What is the linear velocity of the club head if the radius is 0.8 m?
A small, 300 cart is moving at 1.90 on an air track when it collides with a larger, 1.00 cart at rest. After the collision, the small cart recoils at 0.890. Evaluate the speed of the large cart after the collision?
What uniform magnetic field, applied perpendicular to a beam of electrons moving at 7.30 x 106 m/s, is required to make the electrons travel in a circular arc of radius 0.460 m?
Bill and Donna are playing outside when their mother calls them for lunch. Bill is 10.0 m from the house and can run at a speed of 12 km/h. Donna is faster, running at 14 km/h, but is 20.0 m from the house. Draw a graph to determine who gets to t..
A flashlight on the bottom of a 4.45 m deep swimming pool sends a ray upward and at an angle so that the ray strikes the surface of the water 1.65 m from the point directly above the flashlight. What angle (in air) does the emerging ray make with t..
A cosmic ray travels 60 {\rm km} through the earth's atmosphere in 420 \mu s, as measured by experimenters on the ground
Two resistors (connected in series with each other) and a 15 V battery are connected in a loop. What is the voltage drop across the second resistor
a 122-cm-long 5.00 g string oscillates in its n 3 mode with a frequency of 190 hz and a maximum amplitude of 5.50 mm.
The fundamental frequencies from a guitar string and a 440-Hz tuning forkinitially give 3 beats per second. However, when the string isloosened slightly, both its fundamental frequency and the beatfrequency decrease. Find the initial fundamental ..
