Assuming that the magnitude is additive, then you simply have to add the brightness four times. This is because each star has 2 magnitudes of 8.34. As a result, you have to add 4 magnitudes of 8.34. The solution is as follows:
Magnitude = 4(8.34)
Magnitude = 33.36
The sea level would rise because the snow and glaciers are water
Answer:
d=0.02m
Explanation:
The key of the exercise is to be able to graph the problem to be able to develop it. After that you simply proceed through a triangular relationship.
Then I leave the graph of the problem and give the solution.
So things, under the given relationship, we have,
<em>
*The value of 0.04 is taken because the triangle given in the graph must be divided in half, to obtain rectangular triangles.</em>
Explanation:
I think it is the third image as marked in the diagram I kept above because as we know first class levers have the fulcrum between the force and the load
Answer:
Atomic radius decreases moving from left to right across a period.
Explanation:
When we move left to right across a period, the size of atoms generally decreases. It is because within the period the outer electrons are in same valence shell and the number of electrons and proton increases moving from left to right across the the period. It increases the effective nuclear charge resulting in the increased attraction of electron to the nucleus that causes the decreased radius of the atoms.
