Answer: B
Cohesion makes water stick together, which is vital in transporting nutrients from tree roots to other parts of the plant.
Answer:
Explanation:
Impulse = change in momentum
Initial momentum = mass x initial velocity = 100 x 5 = 500 kg m/s
final momentum = mass x final velocity = 100 x - 4 = -400 ( - ve sign due to reversal of direction )
change in momentum = final momentum - initial momentum
= - 400 - 500 = - 900 kg m/s .
As it is - ve , it acts upwards .
So magnitude of impulse on Perter = 900 kg m/s
Answer:
Lateral inversion is a phenomenon in which left appears to be right and vice versa. It is due to direction that light follows when it strikes a reflecting surface, generally a mirror.
Answer:
Explanation:
We are given that
Charge=q=
Potential difference=V=3 V
We know that
Work done=
Using the formula
Work done by charge to move from the negative terminal to the positive terminal of battery=
J
Work done by charge to move from the negative terminal to the positive terminal of battery=
