A rifle bullet is fired horizontally off the top of an ocean-based drill site. If the air resistance is negligible and the vertical distance to the water is 35 m, what additional information is needed to determine the time required for the bullet ot hit the water? (g = 9.8 m/s2) A) The initial velocity of the bullet B) The horizontal distance the bullet travels. C) The mass of the bullet. D) No additional information is needed
What is the capacitance of this capacitor. Estimate the terminal speed of a wooden sphere (density 0.810 g/cm3) falling through air, if its radius is 8.00 cm and its drag coefficient is 0.5.
Calculate the magnitude of B when the force on wire. The time constant of an RC circuit is 5.5 s. How much time t is required for the capacitor (uncharged initially) to gain one-half of its full equilibrium charge.
The 3.10 kg, 34.0-cm-diameter disk is spinning at 350 rpm How much friction force should the brake apply to the rim to bring the disk to a halt in 2.20 s.
You are lowering two boxes, one on the top of the other, down the ramp by pulling on a rope parallel to the surface of the ramp.
A long, straight wire carries a 25.0 current. An electron is fired parallel to this wire with a speed of 280 in the same direction as the current, 2.30 from the wire.
A pressure of 10 Pa is applied through a piston uniformly on the surface of water in a cylinder. How much of this pressure if it is 80 cm deep?
Two identical metal spheres and are connected by a plastic rod. Both are at first neutral. 6.0×10^12 electrons are added to sphere , then the connecting rod is removed.
find the minimum thickness for constructive interference of visible light with a wavelength of 595 nm.
A pump, submerged at the bottom of a well that is 35m deep, is used to pump water uphill to a house that is 50m above the top of the well, as shown above. The density of the water is 1000 kg/m3. All pressures are gauge pressures. Top of well pipe to ..
Two rocks are thrown off the edge of a cliff that is 15.0 m above the ground. The first rock is thrown upward, at a velocity of +12.0 m/s. The second is thrown downward, at a velocity of 12.0 m/s.
As you sit facing your computer screen, electrons are directed from a source at the back of the computer toward you and are deflected by a magnetic field. Which direction must the magnetic field be oriented in order to direct the electrons to the ..
Two charged spheres are 15 cm apart. They are moved, and the force on each of them is found to have been quadrupled. How far apart are they now.
