What is the total capacitance of a circuit containing a 3microfarad capacitor and a 2microfarad capacitor in series.

For capacitors in series (1/Total capacitance)=(1/capacitance1)+(1/capacitance2).1/C=[(1/(310^-6))+(1/(210^-6))]^-1Total capacitance=1.2*10^-6=1.2microfarad

A curve has equation y = 3x^3 - 7x + 10. Point A(-1, 14) lies on this curve. Find the equation of the tangent to the curve at the point A.

Firstly, we define a tangent as a straight line touching a curve at 1 point only.We can describe a straight line using this linear relation:y - y1 = m.(x - x1)We know a point on this...

Messenger RNA (mRNA) is used during translation to form polypeptides. Describe how mRNA is produced in the nucleus of a cell.

RNA polymerase scans the antisense DNA strand in the 3’ to 5’ direction, until it locates a promotor region. RNA polymerase then unwinds the DNA by breaking the hydrogen bonds between the complementary ba...
