This law exaplains the speed of planets around the sun, the speed of the planet increases as it nears the sun and decreases as it recedes from the sun.

From the findings, the astronomical unit of the Mercury is 0.387 and the orbital period is 0.24 year.

$T \propto a^{3/2}$

$T = ka^{3/2}\\\\k = \frac{T}{a^{3/2}}$

From the equation above, as the semimajor axis of a planet increase, the orbital period will decrease and the speed of the planet will decrease.

A researcher is interested in finding out if the amount of amylase, a digestive enzyme found in saliva responsible for digesting

kogti [31]

The answer is <span>Take consistent amounts of saliva samples from a number of people who have not eaten in 8 hours and measure the quantity of amylase in each sample.

First, the researcher needs to know the quantity of amylase in the <u>same</u> amount of saliva. Thus the amount must be consistent and not varying.
Next, people must not eat in 8 hours, so they are all in the same condition at the moment of collecting saliva. If some eat immediately before the sample collecting while some eat 8 hours before, the content of their saliva will be different.
For the correct results, all conditions must be the same.</span>
