"The distance that the force moves" is the one among the following choices given in the question that must be increased, if a simple machine reduces the strength of a force. The correct option among all the options that are given in the question is the first option or option "A". I hope the answer helped you.
<span>I don't think there is enough information from the question. If you are asked to calculate the number of microbes in a certain area., then it should be that the total area or maybe the volume of that should be given so you can estimate the number of microbes. Hope this helps.</span>
The total time is 6.45 s
Explanation:
The motion of the car is a uniformly accelerated motion, so we can use suvat equations.
In the first part,
(initial velocity)
(acceleration)
(time of the first part)
So, we can find the velocity of the car after the first part, by using

This is therefore the initial velocity of the second part:

(acceleration in the second part)
(final velocity)
And therefore,

So, the total time is
