A tuning fork with a frequency of 288 Hz (D) is placed over anopen pipe which has one end submerged in water. If the temperatureof the air in the pipe is 22.0 Degree Celisus, how much of the pipehas to be out of the water in order to play the fundamental?
How much charge can be placed on a capacitorwith air between the plates before it breaks down, if the area ofeach of the plates is 6.00cm2? Find the maximum charge if bakelite isused between the plates instead of air.
A softball player swings a bat, accelerating it from rest to 5.0 rev/s in a time of 0.25 seconds. compute the torque the player applies to one end of it
A charging bull elephant with a mass of 5240 kg comes directlytoward you with a speed of 4.55m/s. You toss a 0.150 kg rubber ballat the elephant with a speed of 7.81 m/s.
Suppose |L| = 10 and r = 2i + 3j + 4k and |p| = 10. What is the angle between the radius and momentum vectors
A car dealer claims that his product would accelerate at a constant rate from rest to a speed of 200 km/hr in 8s. What approximate distance will the car travel.
Joseph is standing 0.80 meters in front of a big spherical mirror (concave mirror), and sees his image upright and magnified 3.0x bigger than he is. Find the radius of curvature of the mirror
A state trooper chases a speeder along a straight stretch of road; both vehicles move at 136 km/h. The siren on the tropper's vehicle produces a sound of 490 Hz. What frequency is heard by speeder? (Take the speed of sound in air to be 343 m/s.)
A charge of +3.3 micro-Coulombs is placed in a capacitor without a dielectric. It starts from rest and accelerates toward the negative plate. After it has traveled 309.2 cm, it is moving at 7.2 x 103 m/s.
