B. evaporation
c. condensation
They are opposite processes that involve the same transfer of energy
Answer:
moves into a region of higher potential
Potential difference = 835 V
Ki = 835 eV
Explanation:
given data
initial speed = 400000 m/s
solution
when proton moves against a electric field so that it will move into higher potential region
and
we know Work done by electricfield W is express as
W = KE of proton K
so
q × V = 0.5 × m × v² ......................1
put here va
lue
1.6 × × V = 0.5 × 1.67 × × 400000²
Potential difference V = 1.336 × 10-16 / 1.6 × 10-19
Potential difference = 835 V
and
KE of proton in eV is express as
Ki = V numerical
Ki = 835 eV
Answer:
The average force exerted on the pier is N
Explanation:
Given :
Mass of ship Kg
Distance m
Velocity
Now find the average velocity,
Now find the time taken by ship to travel 4.44 m.
sec
Now calculating average force,
Where = 0.652
N
Therefore, the average force exerted on the pier is N
Convergent and Counterclockwise
