Explanation:
The acceleration of a body is defined as the rate of change of velocity per unit time. Its mathematical form is given by :
Here,
u is initial speed of a body
v is final speed
t is time taken
Uniform acceleration means that the velocity of an object changes by an equal amount in every equal time period. Hence, the correct option is (c) " Its velocity increases by increasing amounts in equal time intervals".
Answer:
Internal resistance = 0.545 ohm
Explanation:
As per ohm's law we know that
here we know that
i = electric current = 2.75 A
V = potential difference = 1.50 Volts
now from above equation we have
now we have
