Acar with mass 1500 kg moves with constant velocity of 36 m/s. the driver sees a group of cows in front and he immediately steps on the brake pedal and manage to stop the car in 6 s. the distance of the cows from the car when the driver spotted them is 160 m. how far are the cows from the car when the car stops?

The mini-refrigerator fire was most likely caused by what type of wiring?

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.

A6.0-μf air-filled capacitor is connected across a 100-v voltage source. after the source fully charges the capacitor, the capacitor is immersed in transformer oil (of dielectric constant 4.5). how much additional charge flows from the voltage source, which remained connected during the process?
