Answer:
Option (c) is correct.
Explanation:
Acceleration of an object is given by the formula as follows :
Where
u and v are initial and final velocity
t is time
(v-u) is also called the change in velocity
So, the acceleration of an object is equal to the rate of change of velocity. Hence, the correct option is (c) " Change in its velocity divided by the change in time".
Answer:
The electric field between the plates is 120 V/m.
(c) is correct option.
Explanation:
Given that,
Potential difference = 12 volt
Distance = 10 cm = 0.1 m
We need to calculate the electric field between the plates
Using formula of electric field
Where, V = potential difference
d = distance between the plates
Put the formula
Hence, The electric field between the plates is 120 V/m.
