8. A 2000 kg car is traveling at 40 mi/h. The brakes are applied so that the car can stop for a red light. The coefficient of friction between the tires and the road
is 8.
(a) Sketch a force diagram for the stopping car
[b] Calculate the friction force acting on the car
(c) Determine the acceleration of the stopping car

Asystem containing an ideal gas at a constant pressure of 1.22×10^5 pa gains 2140 j of heat. during the process, the internal energy of the system increases by 2320 j. what is the change in volume of the gas?

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?

Which accounts for an increase in the temperature of a gas that is kept a constant volume
