The mass of the sun is 2.13525×10^30 kilograms. The mass of Mercury is 3.285×10^23 kilograms.

Rama09 [41]

Answer:

The mass of Sun is $65\times 10^5$ times greater than mass of Mercury.

Step-by-step explanation:

We are given that

Mass of the sun= $M=2.13525\times 10^{30}$ kg

Mass of Mercury, $m=3.285\times 10^{23}$ kg

We have to find how many times greater is the mass of the sun than the mass of Mercury.

Mass of sun/Mass of mercury= $\frac{2.13525\times 10^{30}}{3.285\times 10^{23}}$

Mass of sun/Mass of mercury $=0.65\times 10^{30-23}$

Using the property

$a^x/a^y=a^{x-y}$

Mass of sun/Mass of mercury $=0.65\times 10^{7}$

Mass of sun/Mass of mercury $=65\times 10^5$

Mass of Sun= $65\times 10^5$ times Mass of Mercury

Hence, the mass of Sun is $65\times 10^5$ times greater than mass of Mercury.

A 12-foot cable attached to the top of the mast of a sailboat is fastened to a point on the deck 4 feet from the base of the mas

Vilka [71]

Answer:

The height of the mast is 8√2 feet

Step-by-step explanation:

In this question, we are asked to calculate the height of the mast given the information in the question.

Please check the attachment for diagrammatic representation.

From the diagrammatic representation, we can conclude that we are asked to calculate the value of the third side of a right angled triangle, given the length of the two other sides.

Using the pythagoras’s theorem;

Square of hypotenuse = square of opposite + square of adjacent

From the diagram, we can see that the length of the cable represents the hypotenuse.

Hence;

AB^2= BC^2 + AC^2

12^2 = 4^2 + AC^2

144 = 16 + AC^2

AC^2 = 144 - 16

AC^2 = 128

AC = √128

AC = 8√2 feet
