You are researching personal watercraft (PWC) safety. These vehicles have a well known safety issue in which the rider loses stearing control when there is no thrust from the engine.
Light from a laser with a wavelength of 760 nm is directed at a diffraction grating of 1500 lines/cm. Calculate the distance between adjacent bright fringes
Suppose you intercept 5.0 x 10-3 of the energy radiated by a hot sphere that has a radius of 0.019 m, How much energy do you intercept in 3.2 min
Two slits, each 1.47×103 m wide are separated, center to center, by a distance of 5.88×103 m. What is the number of the first interference-caused bright fringe which is dark because of diffraction
The magnitude of the force exerted by a spring is given by F = kx where x is the amount of stretching/compressing of the spring. What must be the units associated with k expressed in terms of fundamental SI units?
A circular coil (radius = 0.40 m) has 160 turns and is in a uniformmagnetic field. If the orientation of the coil is varied through all possible positions,the maximum torque on the coil by magnetic forces is 0.16 N⋅m when the current in thecoil is..
A 1000kg car moving 40m/s skids to a stop. During the skid, the only force is the frictional force between the tires and the road, which is 6000N. Use work and energy to find the distance the car moves before coming to a stop.
