A vertical electric field of magnitude 2.00 3 104 N/C exists above the Earth’s surface on a day when a thunderstorm is brewing. A car with a rectangular size of
6.00 m by 3.00 m is traveling along a dry gravel roadway sloping downward at 10.08. Determine the electric
flux through the bottom of the car.

Aspecimen of oil having an initial volume of 580cm^3 is subjected to a pressure increase of 4.0 mpa, and the volume is found to decrease by 0.40 cm^3. (a) what is the bulk modulus of the material? (b) what is the compressibility of the material?

Which of the following can enter and exit a closed system? a. matter and energy b. neither energy nor matter c. matter but not energy d. enrgy but not matter

What would occur if the index of refraction of a material was less than n=1? the speed of light would increase to a speed larger than the maximum speed of light in a vacuum. the light wave would not bend at all though the material. the light wave would not be able to refract and would instead reflect off of the material. the speed of light would reduce to values close to 0 m/s.
