Since earth is attracted to the sun, why doesn't it fall into the sun? a. because it has too much mass to move toward the sun b. because it has sufficient tangential velocity c. because there is an equal force holding it away from the sun d. because it has too much inertia to move toward the sun e. all of the above

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

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)

What is part of a line has one endpoint and continues in one direction?
