The answer to this question would be electron.
Electron is located on the outer side of the atom and constantly moving in an orbit so its location cannot be accurately determined. The cloud around the center of the atom is drawn to picture the orbit.
Neutron and proton located in the middle of an atom in a part that called nucleus. Nucleus location is kept at the center and it doesn't move.
Answer:
New pressure group is N
Explanation:
The Repetitive Dive table has to be checked, the residual nitrogen for the maximum depth of 38 feet as a "D" diver, then add that to the actual dive time to get the total nitrogen time. The total nitrogen time and the maximum depth of 38 feet would put you on a pressure group N.
Answer:
Train wheels and rails are both made of steel, and the steel-steel friction coefficient is around 0.25. As a result, the stopping time and distance will be three to four times that of a car.
Answer:
a) To the nearest tenth the average value of the measures is 217.4cm
b) The standard deviation for the four measurements is 0.415
Explanation:
The average is the result of adding all the values and dividing by the number of measures, in this case 4 then
a) To the nearest tenth the average value of the measures is 217.4cm
The standard deviation equals to the square root of the variance, and the variance is the adition of all the square of the difference between the measure and the average for each value divided by the number of measurements
So first, we must calculate the variance:
.
.
.
.
.
This represent the difference between the average and the measurements.
Now calculate the standard deviation
Standard deviation =
Standard deviation =
Standard deviation = 0.415
b) The standard deviation for the four measurements is 0.415
This measure represent a standard way to know what is normal in this sample. so the differences between the average should be of ±0.415
