A photographer uses a lens with f = 50mm to form an image of a distant object on the CCD detector in a digital camera. The image is 1.0mm high, and the intensity of light on the detector is 3.2W/m2 . She then switches to a lens with f = 300mm that is the same diameter as the first lens.
Part A What is the height of the image now?
Part B What is the intensity now?
A proton is released from rest inside a region of constant, uniform electric field E1 pointing due North. 27.3 seconds after it is released, What is the ratio of the magnitude of E2 to the magnitude of E1
You're carrying a 4.0-m-long, 25 poles to a construction site when you choose to stop for a rest. You place one end of the pole on a fence post and hold the other end of the pole 35 from its tip. How much force should you exert to keep pole motionles..
A 70 kg bicyclist rides his 7.8 kg bicycle with a speed of 16 m/s. How much work must be done by the brakes to bring the bike and rider to a stop.
What is the magnitude of an electric field in which the electric force on a proton is equal in magnitude to its weight, What must the charge (sign and magnitude) of a particle of mass 1.40g
At t = 0, a particle leaves the origin with a velocity of 12 m/s in the positive x direction and moves in the xy plane with a constant acceleration of (-2.0i+4j) . At the instant the y coordinate of the particle is 18 m, illustrate what is the x ..
If a car travelling at 52 km/h will skid 18 m when its brakes lock, how far-off will it skid if it is travelling at 120 km/h when its brakes lock.
Sketch a force diagram for the desk.
What is the net force exerted on the skier, assuming his acceleration is constant.
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.
Assume air resistance is negligible; from what height (in cm) above the compressed spring was the block dropped.
An initially motionless test car is accelerated uniformly to 1.20 × 102 km/h in 8.68 seconds before striking a simulated deer. The car is in contact with the faux fawn for 0.455 seconds, after which the car is measured to be traveling at 65.5 km/h..
