photons and convection - density differences makes bubbles of hot stuff float up. pretty sure
Answer:
His walks cover 2km+2km+2km = 6 km.
Explanation:
Let East be positive. Since West is the opposite direction, it is negative. His displacement is dependent on direction. 2km east + 2km west + 2km east = (2-2+2)km = 2km. His displacement is 0 because he ends up back where he started.

Answer with Explanation:
We are given that
Force=F=112 N
Distance,
Time, t=3.33 minutes
We have to find the work done by Johnson on the bag and the power generated by Johnson.
Work done, W=
Using the formula
Work done, W=
Power, P=
Using 1 minute=60 s
Hence, the power generated by Johnson=33.3 watt
Answer:
impulse applied to an object produces an equivalent vector change in its linear momentum, also in the resultant direction. The SI unit of impulse is the newton second (N⋅s), and the dimensionally equivalent unit of momentum is the kilogram meter per second (kg⋅m/s).
