Each of the objects above is composed of identical thin sticks of uniformly distributed mass 5.51 kg and length 0.737 m. what is the moment of inertia of each object about a rotation axis perpendicular to the screen and passing through the black dot?

An airplane flies eastward and always accelerates at a constant rate. at one position along its path it has a velocity of 34.3 m/s, it then flies a further distance of 40100 m and afterwards its velocity is 47.5 m/s. find the airplane\'s acceleration and calculate how much time elapses while the airplane covers those 40100 m.

What is the power rating of the lightbulb if 3.0 a flow through it when connected to a 15 v battery

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
