If an Oreo cookie is 0.654 cm thick, how many Oreos does it take to reach the moon

Chemistry
1 answer:
VARVARA [1.3K]3 years ago
3 0

It takes 5.89 x 10¹⁰ Oreos to reach the moon.

The <em>average</em> distance from the Earth to the moon is 385 000.6 km.

<em>Metres = </em> 385 000.6 km × (1000 m/1 km ) = 385 000 600 m

<em>Centimetres</em> = 38 500 060 000 m × (100 cm/1 m) = 38 500 060 000 cm

<em>Oreos</em> = 38 500 060 000 cm × (1 Oreo/0.654 cm) = 58 900 000 000 Oreos

= 5.89 x 10¹⁰ Oreos

Point N is on line segment MO. Given NO = 2x – 3, MO = 3x + 5, and
Zigmanuir [339]

Answer:

MO = 20

Explanation:

Given that: MO = 3x + 5

                  MN = 2x + 3

                  NO = 2x - 3

But,

MO = MN + NO

So that;

3x + 5 = (2x + 3) + (2x - 3)

3x + 5 = 2x + 3 + 2x - 3

3x + 5 = 4x

3x - 4x = -5

-x = -5

Multiply through by minus,

x = 5

Thus,

MO = 3x + 5

      = 3(5) + 5

      = 15 + 5

MO = 20

The length of MO is 20.

Hanna hypothesizes that granite is denser than sandstone. How can Hanna test her hypothesis?
kherson [118]
To test if the hypothesis is correct, a good way is to think of it this way:
Density = mass/volume, right?
Calculate the mass and volume of each and do the equation; this will test your hypothesis.
You will be left with the density of each. But, make sure that the sample sizes are the same (controlled variable) otherwise it will be an unfair test.

A sample of gas kept at a constant pressure, is heated from 273 k to 373 k. If the initial volume is 3.00 L, what is the new vol
zlopas [31]

Answer: 4.10 liters

Explanation:

Given that:

initial volume of gas V1 = 3.0L

initial temperature of gas T1 = 273K

new volume V2 = ?

new temperature T2 = 373K

Since, only volume and temperature are involved, apply the formula for Charle's law

V1/T1 = V2/T2

3.0L/273K = V2/373K

To get the value of Z, cross multiply

3.0L x 373K = 273K x V2

1119 = 273V2

Divide both sides by 273

1119/273 = 273V2/273

4.10L = V2

Thus, the new volume is 4.10 liters
