Determine what is the electric field strength (in Newton's/coulomb) at a point in space where a proton (m = 1.67E-27 kilogram) experiences an acceleration of 3.1E+04 m/s2?
Suppose a steel strut having a cross-sectional of area 4.00 10-4 m2 and length 2.80 m is bolted between two rigid bulkheads in theengine room of a submarine. Calculate the compressional stress in the strut
A room with 3.0-m high ceilings has a metal plate on the floorwith V=0V and a separate metal plate on the ceiling. How high does the ball go if the ceiling voltage is 3.0*10^6 V
A van der Waals gas undergoes an isothermal expansion from specific volume v1 to specific volume v2. Calculate the change in the specific Helmholtz function for this process.
A vessel which contains an ice-water mixture at 0C is in thermal contact with a water-steam mixture at 100 C. What is the change in the entropy of the water-steam mixture at 100C
A wire loop of radius 0.40 m lies so that an external magnetic field of magnitude 0.40 T is perpendicular to the loop. Find the magnitude of the average induced emf in the loop
One of the dangers of tornados and hurricanes is the rapid drop in air pressure that is associated with such storms. Assume that the air pressure inside of a sealed house is when a hurricane hits.
