Question

( frac{d Q}{d t} I )
( d Q=I d t )
( d theta=left(3 t^{2}+2 t+5right) d t )
( int d Q=int_{0}^{2}left(3 t^{2}+2 t+5right) )
( =left[t^{3}+t^{2}+5 tright]_{0}^{2}=3 t^{2}+2 t+5 )
( =frac{8+4+10}{10+4} )
( =frac{10}{10+4} )

# T Single Choice The current flowing through a wire depends on time as I = 31- +21+5. The charge flowing through the cross-section of the wire in time from 1 = 0 to 1 = 2s is: A 220 B. 200 c 150 DSC
