A soldier on a firing range fires an 8-shot burst from an assault weapon at a full automatic rate of 1000 rounds per minute. Each bullet has a mass of 7.42 g and a speed of 295 m/s relative to the ground as it leaves the barrel of the weapon.
a). Calculate the average recoil force (in N) exerted on the weapon during that burst.
The work function for potassium is 2.24 eV. If potassium metal is illuminated with light of wavelength 300 nm
what is the difference between intersecting snd perpendicular lines? can two line exist that are not intersecting or

A bullet of mass 0.5 kilogram is headed at horizontal speed 130 m/s toward a block of mass 4.5 kilogram resting on a horizontal frictionless surface.Find what average force did the block exert on the bullet
A tank of compressed air of volume 1.0 m3 is pressurized to 40.0 atm at T = 273 K. A valve is opened and air is released until the pressure in the tank is 33.0 atm. How many air molecules were released?
Photons of wavelength 58.0 pm are Compton-scattered from a free electron in an aluminum block, at 75.0o from the original direction. What energy (in electron volts) has been imparted to each electron
A Carnot engine whose high-temperature reservoir is at 680K takes in 570J of heat at this temperature in each cycle and gives up 350J to the low-temperature reservoir. What is the temperature of the low-temperature reservoir
A train started from rest and moved with constant acceleration. At one time it was move traveling at 33.0 m/s, and 160 meter farther on it was traveling at 54.0 m/s. Determine the time required to attain the speed of 33.0 m/s
