Number of calories burnt is calculated based on the hours of exercise which is the response variable on this scenario
Answers
Answer:
Given:
Charge through a cross section of the conductor is given by ;
q = 2 {t}^{2} + 5tq=2t
2
+5t
To find:
Current passing through that cross section at t = 2 seconds
Concept:
Current is a scalar quantity represented by the rate of charge flow through the cross section of any conductor.
Calculation:
q = 2 {t}^{2} + 5tq=2t
2
+5t
= > i = \dfrac{dq}{dt}=>i=
dt
dq
= > i = \dfrac{d(2 {t}^{2} + 5t) }{dt}=>i=
dt
d(2t
2
+5t)

= > i = 4t + 5=>i=4t+5
Putting t = 2 second , we get :
= > i = (4 \times 2) + 5=>i=(4×2)+5
= > i = 13 \: ampere=>i=13ampere
So final answer is :
Current at that instant is 13 Amp.
