If a molecule diffusing through extracellular fluid travels 1 mm in 1 sec, how long will it take that molecule to diffuse 1 cm?

1 answer:

5 0

To determine the time, we can simply do dimensional analysis from the given values. We are given the distance the fluid travels per sec and we are given the required distance to travel. Therefore, we simply divide the required distance with the rate given. It is important to take note with the units.

t = .01 m / .001 m/s = 10 s

You are driving down the road at 35 mph. what is your speed in m/s?

Lady_Fox [76]

Answer:

15.64m/s

Explanation:

This is a unit of speed which is the rate of change of distance with time

I am driving at 35mph: and I want to express as m/s

mph means miles per hour

This suggests that I have to convert miles to m and hrs to secs:

for distance 1.609km = 1mi

1000m = 1km

for time:

1hr = 60minutes

1min = 60seconds

Using dimensional analysis:

$\frac{35miles}{1hour}$ x $\frac{1.609km}{1miles}$ x $\frac{1000m}{1km}$ x $\frac{1hour}{60min}$ x $\frac{1min}{60seconds}$

= 15.64m/s

the 1st one is balanced, the 2nd isn't (the number of Mg differs from left 1 to right 2).

The third is also not balanced, 2 F left,2*3=6 on the right
