A 35.0 cm diameter coil comprises of 34 turns of circular copper wire 2.0 mm in diameter. A uniform magnetic field, perpendicular to the plane of the coil, changes at a rate of 4.10 x 10^-3 T/s. (i
Primarily, prior to the engine is ignited, the rocket sits at rest on top of the spring. Determine how much is the spring compressed? After the engine is ignited, determine the rocket's speed if the
A rigid tank has 1.60 moles of an ideal gas. Find out the number of moles of gas which should be withdrawn from the tank to lower the pressure of the gas from 23.6 atm to 5.50 atm. Suppose the volum
A rod (boxing practice target) having mass 4.0 kg and length 1.5 m. suspends from a hinge joined to the ceiling. A boxer punches the padded end of the target so that it is moving at a speed of 5 m/s
Assume that a ruler(100cm) is asymmetrical, and it is balanced at the 45 cm mark (at the center of mass). Now, mass M is hung on the ruler at 100 cm mark. Where should you hang mass 1.82M so the sys
A gymnast of mass 53 kg is jumping on the trampoline. She jumps so that her feet arrive at a maximum height of 2.4 m above the trampoline and when she lands; her feet stretch the trampoline down 63
A 50 kg, 5.0m long beam is supported, however not joined to, the two posts one at the left end of the beam, one at 3.0 m from the left end of the beam. A boy of 20 kg begins walking all along the b
The beam of white light (continuous spectrum from 400 to 700 nm) is incident at the angle of 45 degrees on the two parallel glass plates separated through an air film 0.001 cm thick. The reflected l
The cord's un-stretched length is around 30.0 m. (i) Supposing that the bungee cord follows Hooke's law if it stretches, determine its spring constant.
At what rate is the gravitational potential energy lost by the water of the Niagara River? The rate of flow is around 5.5 106 kg/s.
The 10 capacitor initially charged to 30 is discharged via a 2.7 resistor. Determine how long does it take to decrease the capacitor's charge to 1.0?
Without computations, which vehicle undergoes a greater change in velocity throughout the collision? Determine how do you know?
When the Merry-go-round is spinning at 0.2 revolutions per second before the child jumps onto its rim, determine the final angular speed of the merry-go-round and child?
At local swimming hole, a favorite trick is to run horizontally off a cliff which is 6.5 m above the water. One diver runs off the edge of the cliff, tucks to the "ball," and rotates on the way down
A gun of 1200 Kg mounted on wheels shoots an 8.00 Kg projectile having a muzzle velocity of 600 m/s at an angle of 30.0 degrees above the horizontal. Determine the horizontal recoil speed of the gun
Remember that the radius of a sphere is equal to half its diameter! How does your calculated density (in grams per cubic centimeter) compare to the density of water? Would you expect this asteroid t
