Two bicycle riders start at the same point. Bicycle I rides 0.50 m due east, then 0.8 m at 30° North of East Bicycle 2 also undergoes two displacements: the first is 1.6 m at 40° east of
north. What must be the magnitude and displacement of Bicycle 2 if it is to end up at the new
location of Bicycle l?

Orque can be calculated by multiplying the force (n) applied at 90? to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n? m. if the force (at 90? to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?

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.
