The mass of an electron is approximately 9 × 10-28 grams, while the mass of a neutron is approximately 2 × 10-24 grams. Which of the following is true?
A.
The mass of a neutron is approximately 2,000 times the mass of an electron.

B.
The mass of a neutron is approximately 20,000 times the mass of an electron.

C.
The mass of a neutron is approximately 10,000 times the mass of an electron.

D.
The mass of a neutron is approximately 1,000 times the mass of an electron.

A.  Approximately 2000 times the mass of an electron.

Step-by-step explanation:

Lets do the division:

Mass of neutron / mass of electron

2 × 10^-24  / 9 x 10^-28

= 0.222 x (10^(-24 - (-28))

= 0.2222...  x 10^4

= 2222.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
