If the diameter of the red marble is 3.0 cm, and by using the formula for volume, what is a good approximation of its volume? cm3 determine the initial volume of water in the graduated cylinder. if you added the red marble to the graduated cylinder and it sinks, what final volume should the water level indicate?

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?

Photons with the highest energy have the longest period

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
