What sort of interference is present in the bright areas of the graph? In the dark areas? Which properties in the experiment changed the spacing between the bright bands on the screen?

Would the pattern on the screen have changed if there had been three sources of light? Explain your answer.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =

3. dark matter

empty space could also be a simple vacuum
