Speed is calculated using the formula distance divided by time. For a distance of 26.2 miles, and a time of 3 hours and 40 minutes, we first convert the time to make it solely in terms of hours. 40 minutes is 2/3 of an hour, so this is a total time of 3 2/3 or 11/3 hours. If we divide 26.2 miles by 11/3 hours, we get a resulting speed of 7.14 miles/hour.
Answer:
activating digestive enzymes, and making ingested proteins unravel so that digestive enzymes break down the long chains of amino acids
Answer:
1g or 10^-3kg
Explanation:
as you know , the density =mass \volume
so you have the mass from the number it self
<h2>
so from this equation, you will get 1 g and you can to SI to be
kg</h2>
To form a 2+ ion, you need to lose two negatively charged electrons. Because metals have relatively empty outer shells, they lose electrons. Metals are on the left hand side of the table, and in order to lose two electrons, you need to have two electrons to start with. The groups of the table are based on the number of electrons an element has in the outer shell, so Group 2 metals will lose two electrons to gain a 2+ charge
