An object with a mass of 2.0 kg is initially at rest at a position x = 0. A non-constant force F is applied to the object over a displacement of 6.0 m, as shown in the graph. What is the total work done on the object at the end of 6.0 m? Write the equation which relates work done and kinetic energy.

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.

The primary structure of a protein refers to the linear sequence of amino acids in the polypeptide chain. the primary structure is held together by covalent bonds such as peptides bonds
