An object of mass M is at rest at the origin at time t=0 . At that time, a force F=At2 (where A is a positive constant and F is in newtons when t is in seconds) is applied to the object. After 2s, the velocity of the object in m/s will be

No because a circle or pie graph usually shows percentages you'd need a line graph

The rearrangement of particles in a physical change. hope this

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.
