Answer:
Elements, such as helium, depicted here, are made up of atoms. Atoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus.
The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
The model of the atom can be broken down into three constituents parts – protons, neutron, and electrons. Each of these parts has an associated charge, with protons carrying a positive charge, electrons having a negative charge, and neutrons possessing no net charge.
Answer:
The population has decreased. (2)
Explanation:
if the birth rate is 14 and no bison immigrate into the population and the death rate and emigration rate add up to 30, then the population has decreased a total of 16 bison
Answer:
You could record yourself doing a cardio exercise such as running or using a jump rope for a certain period of time using a stop watch or a phone timer. Then stop after about 5-10 minutes and using the stop watch see how long it takes for your heart rate to go back to normal.
Explanation:
<h3>Answer</h3>
15 = 1.5 × 10^1
1.5 =1.5 × 10^0
0.015 = 1.5 × 10^-2
0.15 = 1.5 × 10^-1
150 = 1.5 × 10^2
<h3>How to convert to scientific notation</h3>
- Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. Let says it is X
- Count how many places you moved the decimal point. Let say it is Y.
- If you moved the decimal to the left b is positive.
- If you moved the decimal to the right b is negative.
- If you did not need to move the decimal b = 0.
- Write your scientific notation number as X x 10^Y.
