Answer :- A) Milligram is the right answer.


Explanation:-

The mass of a grain of sand is approximately 2..8\times10^{-11}\text{ grams}

We know that 1 gram=1,000 milligrams

Therefore,The mass of a grain of sand is approximately  =2.8\times10^{-11}\times1000\text{ milligram}\\=2.8\times10^{-11}\times10^3\text {milligram}\\=2.8\times10^{-11+3}\text{ milligram}....\text{[by using law of exponents]}\\=2.8\times10^{-8}\text{ milligram}

Thus, the  mass of a grain of sand is approximately 2.8\times10^{-8}\text{ milligram}.

Write the equation of the line with a slope of 17 and passing through the point (0, 0)
Mkey [24]
The equation for a line is y=mx+b. where m is the slope and b is the y intercept.
The slope of 17 is provided. This means m=17. The point (0,0) tells you the y intercept is 0. This means b=0

Plugging these into the equation and simplifying:
y=17x+0

y=17x

Hope this helps :)
