A transparent film has a thickness of 0.003250 cm, and a refractive index of 1.4000. Find
(A) the order of interference at theta=0 degrees and
(B) the first 4 angles at which red light of wavelength 6500 angstroms will form bright-light fringes.
A torque of 60 Nm producing a counterclockwise rotation is applied to the wheel about its axle. A frictional torque of 10 nm acts at the axle.If the wheel is observed to accelerate at the rate of 2rad/s2 under the influence of these torques, what i..
The springs of a 1300kg car compress 6.00 mm when its 68 kg driver gets into the driver's seat. If the car goes over a bump, what would be the frequency of vibrations.
(8c1p14) Time standards are now based on atomic clocks. A promising second standard is based on pulsars, which are rotating neutron stars, What is the mass of gasoline (? = 0.680 g/cm3) in a 94.6 L gasoline tank? (kg)
A non-uniform bar 5 meters has a center of gravity 1 meters from the heavy end. If it is placed on the edge of a block 1 meters from the light end and a weight of 1497N is placed at the light end of the bar, it will be balanced. What is the weight..
Ten cars at an intersection are blowing their horns simultaneously, What is the average sound level for each car
You are piloting a small plane that can maintain an air speed of 136.5 kt (knots, or nautical miles per hour) and you want to fly due north (azimuth = 000°) relative to the ground.
A chair of weight 130 lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of = 45.0 fixed at an angle of 39.0below the horizontal and the chair slides along the floor.
Suppose that a simple pendulum consists of a small 58.0 g bob at the end of a cord of negligible mass. What is the pendulum's length
A girl on a sled coasts down a hill. Her speed is 7.60 m/s when she reaches level ground at the bottom. The coefficient of kinetic friction between sled's runners and the hard, icy snow is 0.04, and the girl and sled together weigh 644N.
A block of mass 12-kg slides from rest down a frictionless 34° incline and is stopped by a strong spring with k = 1.0x 10^4 N/m. The block slides 3 m from the point of release to the point where it comes to rest against the spring.
