A thunderstorm cloud holds about 6,200,000,000 raindrops. Which of the following shows this number in scientific notation? Answe
maksim [4K]

Answer:

the answer is G

which is 6.2*10 to the 9th power.

Step-by-step explanation:

In scientific notation you must leave one digit to the place value of ones

so that one digit is 6

So ue come up with 6.2 when ue eliminate all other zeros and end the decimal point between 6 and 2 and that way you have 6.2*10 to the 9th power

2. If you know the volume of a cube, how do you find its<br> edge length?<br> nel
MakcuM [25]

\huge\boxed{\sqrt[3]{\text{V}}}

The volume of a cube is found by cubing the edge length — or multiplying it by itself twice.

In other words, the volume of a cube is as follows:

V=e*e*e

Simplified:

V=e^3

To find the edge length from the volume, you'd have to do the opposite, which is to find the cubic root.

Compare the light gathering power of an 8" primary mirror with a 6" primary mirror. The 8" mirror has how much light gathering p
tankabanditka [31]

Answer:

1.778 times more or 16/9 times more

Step-by-step explanation:

Given:

- Mirror 1: D_1 = 8''

- Mirror 2: D_2 = 6"

Find:

Compare the light gathering power of an 8" primary mirror with a 6" primary mirror. The 8" mirror has how much light gathering power?

Solution:

- The light gathering power of a mirror (LGP) is proportional to the Area of the objects:

                                           LGP ∝ A

- Whereas, Area is proportional to the squared of the diameter i.e an area of a circle:

                                           A ∝ D^2

- Hence,                              LGP ∝ D^2

- Now compare the two diameters given:

                                           LGP_1 ∝ (D_1)^2

                                           LGP ∝ (D_2)^2

- Take a ratio of both:

                           LGP_1/LGP_2 ∝ (D_1)^2 / (D_2)^2

- Plug in the values:

                               LGP_1/LGP_2 ∝ (8)^2 / (6)^2

- Compute:             LGP_1/LGP_2 ∝ 16/9 ≅ 1.778 times more
