A comet of mass 4.5 E22 kg moving at 10000 m/s collides withthe earth, initially at rest, and stick. The mass of the earth is5.98 E24 kg. Find the final speed of the earth.
A particle has a position vector given by r = (12t)i ^ + (60t-25t2)j ^ , Find the instantaneous-velocity and instantaneous-acceleration vectors as functions of time t
Sodium ions (Na+) move at 0.861 m/s through a bloodstream in the arm of a person standing near a large magnet. what would be the magnetic force on the arm
Water is in the big beaker in the figure on the left. Scale 1 reads 96 newtons, scale 2 reads 531 newtons, and scale 3 reads 0 newtons. The hanging block has a density of 10 × 10^3 kg/m3. To nearest tenth of a newton what does scale 1 read after t..
If there is a potential difference of V between the metal and the detector, what is the minimum energy that an electron must have
An oscillating block-spring system has a mechanical energy of 2.27 J, an amplitude of 8.07 cm, and a maximum speed of 1.43 m/s. Find (a) the spring constant, (b) the mass (in kg) of the block and (c) the frequency (in Hz) of oscillation.
Water flows at speed of 4.9 m/s through a horizontal pipe of diameter 3.2 cm. The gauge pressure P1 of the water in the pipe is 1.5 atm. What is the gauge pressure of the water flowing through the constricted segment in atm
diamagnetism is caused by:
A 75.0 kg mass sits on an inclined plane, and a rope passing over a pulley at the top connects it to a hanging 125 kg mass. The pulley is frictionless and its mass is negligible. The coefficient of friction between the 75.0 kg block and the plane ..
Do sound waves exhibit diffraction effects? If so, determine the "slit" width that would diffract an audible sound wave (frequency between 20 Hz and 20 kHz). Would a doorway work or do you need a different sized opening?
The magnetic field near the surface of a neutron star has a magnitude of 1.00 108 T. Find the acceleration of an electron near the star moving at 1.08 107 m/s
Compute the final temperature using the ideal gas law and van der Waals equations of state. Assume that Cvm = 3/2 R and the van der waals parameters for Argon are a = 1.355 dm6bar/mol2 and b = 0.0320 dm3/mol.
