Answer: B
Cohesion makes water stick together, which is vital in transporting nutrients from tree roots to other parts of the plant.
Net Force = 600 N
Kinetic Energy = 600 J
(Work done) >> KE since there is no mention of frictional forces
Im not so sure but it should be the
instantaneous speed
B is the correct answer because an object moving ten north m/s will turn into 15m/s which as you can tell is accelerating.
Answer:
Correct option : (c) period.
Explanation:
The time that is required for a vibrating object to complete one full cycle is called the time period. If f is the frequency of a wave, then the relation between the frequency and the time period is given by :

These are the characteristics of a wave. Some other characteristics are wavelength, amplitude, intensity etc. So, the correct option is (c) "period".
