Answer:

Mutual inductance will be $M=1.8\times 10^{-3}Hennry$

Explanation:

We have given induced current $\Delta i=5A$

Time is given as $t=1ms=10^{-3}sec$

We have to find the mutual inductance between the coils

Induced emf is given as e = 9 volt

We know that induced emf is given by

$e=M\frac{\Delta i}{\Delta t}$

$9=M\times \frac{5}{10^{-3}}$

$M=1.8\times 10^{-3}Hennry$

Suppose that, from measurements in a microscope, you determine that a certain bacterium covers an area of 1.50 μm2. Convert this

Paladinen [302]

1 m = 1 000 000 ym

converted other way we can say that:

1 ym = $10^{-6}$ m

Now, since we have ym^2 which is ym*ym which means:
1 ym^2 = $(10^{-6}) ^2 = 10^{-12}$ m

we have 1,5 ym^2 which means that answer is:
$1.5* 10^{-12} m$
