A helium4 atom has 2 protons and 2 neutrons. Its mass is 6.645 * 10^-27 kg. The mass of 4 hydrogen atoms is 6.693 * 10^-27 kg. Subtract the helium atoms mass from the 4 hydrogen and you get 0.048 * 10^-27 kg.

Let f(x) = x^2 - 5x +4 / x-1
Elenna [48]

Answer:

C. 3

Explanation:

You cannot divide by 0.

So plug in g(x) into f(x) in the denominator. The numerator is irrelevant so you don't need to worry about it.

Solve for what value of x will give you a denominator of 0.

I just eyeballed this and found that x=3 give you a denominator of 0.

or you can just plug in and check all the answer choice.

Does data from mass spectrometry indicate that modern scientists have made modifications to Dalton's model? Justify.
serious [3.7K]
Yes, the data from mass spectrometry has helped modern scientists to make modifications to Dalton's model. 

Dalton's model consisted of a single atom and that basically the atom is the smallest object. At the time, no discovered what are inside of atoms. 

Atoms are made up of small particles, protons, neutrons and electrons. A mass spectrometer is an instrument that is able to see what is inside an atom. With this item, scientists have proved that atoms are not the smallest in the world cause the objects in them are smaller.

how did the nature of work shape early colonial society in north america? does it still shape society today?
Ann [662]
Since in colonial North America, many people did not have the luxuries we have now, their entire lives revolved around work. Without a good harvest season or another product to trade for food, a family could easily go hungry and starve to death. As exemplified through Jamestown's "Starving Time," the leader, whose name escapes me at this time, decided that if the colonists were not willing to work, they would not receive any food. The second question is more of an opinion question that I cannot answer for you.
