Answer

1.2864*10^{-3} cm^{2}

Explanation:

First we multiply as normal:

0.00032 cm * 4.02 cm = 0.0012864 cm²

It is important to multiply the units too which is why centimeters become square centimeters.

Then we write the answer in scientific notation:

0.0012864 cm^{2} = 1.2864*10^{-3} cm^{2}

A nerve signal travels 150 meters per second. Determine the number of kilometers that the nerve signal will travel in the same t
joja [24]

Explanation:

It is given that,

A nerve signal travels 150 meters per second. It is the speed of the nerve signal. We need to convert the number of kilometers that the nerve signal will travel in the same time.

We know that,

1 kilometer = 1000 meter

1 hour = 3600 seconds

150\ \dfrac{m}{s}=150\times \dfrac{1/1000\ km}{1/3600\ h}

150\ m/s=540\ km/h

So, the nerve signal will travel at the rate of 540 km/h. Hence, this is the required solution.
