Answer;

-Significant

Explanation;

-Several numbers are considered significant in a measurements. Non-zero digits are always significant. Thus, 569 has three significant digits, and 69.35 has four significant digits.

-Zeros are sometimes significant and sometimes aren't:. Zeroes placed before other digits are not significant; 0.0968 has three significant digits.

-Zeros placed between other digits are always significant; 70063 kg has five significant digits. Zeros placed after other digits but behind a decimal point are significant; 7.90 has three significant digits. Zeros at the end of a number are significant only if they are behind a decimal point.

All object changes are compared with a ____ , which is an object that appears to stay in place?
Kaylis [27]

Answer:

All object changes are compared with a <em>reference</em> , which is an object that appears to stay in place.

Explanation:

In scientific experiments, the changes in the experimental object are observed by comparing the changes with a reference object. In the reference object, no changes are made and conditions are kept normal in it. For example, if we want to measure the distance of two cars from a point, the point will be the reference point from which the distance shall be measured. Hence, all changes are made by comparison from a reference object or point.

Which electron transition would result in the greatest amount of energy to be absorbed? a) n = 4 to n = 1 b) n = 1 to n = 4 c) n
kotegsom [21]

Answer:

b) n = 1 to n = 4.

Explanation:

a ) n = 4 to n = 1 transition represents release of energy because transition is from high energy orbit to low energy orbit.

Similarly c) n = 2 to n = 1 represents release of energy because transition is from high energy to low energy orbit.

d ) n = 1 to n = 3 is also energy absorbing transition but amount of energy absorbed is less as compared with option b) transition .

So the correct option is b)
