larisa86 [58]

Here, F = m * a
F = m * v/t
Here, m = 81 Kg
v = 22 m/s
t = 1,4 s

Substitute their values,
F = 81 * 22/1.4
F = 81 * 15.71
F = 1273 N
So, Closest value from your options is 1300 N

In short, Your Answer would be Option B

Hope this helps!

Convert 2536 mm/min to m/s. Use dimensional analysis.

Deffense [45]

Answer:

<u>As</u><u> </u><u>we</u><u> </u><u>kno</u><u>w</u><u> </u><u>that</u><u>,</u><u> </u>

1 mm/min = 1.66667E-5 m/s
1 m/s = 60000 mm/min

<u>Now</u><u>,</u><u> </u><u>come</u><u> </u><u>to</u><u> </u><u>the</u><u> </u><u>question</u><u> </u><u>-</u><u> </u>

$\\ \implies \sf \: 2536 \times 1.66667E-5 m/s \\ \\ \\ \implies \sf \blue{0.0422666667 \:m/s } \\$

Result : 2536 mm/min = 0.0422666667 m/s.

the decimal reduction time (DRT) is the time it takes to kill 90% of cells present. Assume that a DRT value for autoclaving a cu

kotegsom [21]

Answer:

It takes 10.5 minutes to kill all the bacteria.

Only 1 cell would remain after 9 minutes.

Explanation:

It will take 1.5 minutes to kill 90% of the cells. So, after 1.5 minutes, only 10% would remain. After 3 minutes, only 1% remain. So, to figure out how long it would take to kill a million cells, we have to multiply 1 million by 0.1 repeatedly until the final value is less than 1 that is because when the value is less than 1, it means there are no more bacteria.

So:

$10^6 \times (0.1)^7$ = 0.1

So, you need 10.5 minutes of killing to kill one million cells.

Time taken= 7 x 1.5 minutes = 10.5 minutes.

After 9 minutes you would have:

$10^{6} \times (0.1)^{6}$ = 1 cell left
