Starting from rest, a 1.8 10-4-kg flea springs straight upward. While the flea is pushing off from the ground, the ground exerts an average upward force of 0.37 N on it. This force does +2.6 10-4 J of work on the flea.
(a) What is the flea's speed when it leaves the ground?
m/s
(b) How far upward does the flea move while it is pushing off? Ignore both air resistance and the flea's weight.
m
Light with a wavelength of 618 nm passes through a slit 7.52 wide and falls on a screen 1.88 m away. compute the linear distance on the screen from the central bright fringe to the first bright fringe above it.
Identical samples containing 32P are measured for a period of 1 hr in a counter having an efficiency of 44 percent and a negligible background. From a large number of observations, the mean number of counts in 1 hr is (2.93 x 10^4)
Two very small spheres, each with a mass m = 1.5 g, are suspended from a common axis by insulating threads of length L= 6.0 cm, What is the magnitude of the unknown charge q
A thin 12 cm long solenoid has a total of 490 turns of wire and carries a current of 1.9 A. find the magnitude of the field inside near the center.

What is the acceleration of two falling sky divers.
A hydrometer is used to measure the specific gravity of liquids. For a sure liquid a hydrometer reading indicates a specific gravity of 1.15. What is the liquid's density and specific weight? State the answer in SI units.

Two balls of the same mass are accelerated by different net forces such that one ball gains a velocity twice that of the other ball in the process. Is the work done by the net force acting on the faster moving ball twice that done on the slower mo..
Calculate the magnitude of the planes acceleration. On a level road with its brakes on, a car traveling at 93 km/hr stops within 87 m when the brakes lock and the car slides.
A motorist suddenly notices a stalled car and slams on the brakes, negatively accelerating at 6.2 . Unfortunately this isn't enough, and a collision ensues.
A railroad boxcar that has " due east" momentum of 15,000 kgm/sec collides with and couples with a similar boxcar that has "due west" momentum of 20,000kgm/sec. After collision, the combination has ( ) kgm/sec total of momentum.
