The average density of the material in intergalactic space is approximately 2.5 × 10–27 kg/m3. what is the volume of a lead samp
Lesechka [4]

Answer:

e. 1.8\times 10^{-6}m^3

Step-by-step explanation:

It is given that,

The density of intergalactic space material is 2.5 \times 10^{-27} kg per cubic meter.

And the volume of intergalactic space material is 8.0\times 10^{24} m^3

So the mass of that much intergalactic space material is,

m= \rho\times v, where 'm' is the mass, and 'v' is the volume.

Putting the values we get,

m=2.5 \times 10^{-27}\times 8.0 \times 10^{24}

m=20\times 10^{(-27+24)}=20\times 10^{-3} kg

It is also given that the mass of lead is the same as the mass of the intergalactic space material. Therefore, the mass of lead is 20 \times 10^{-3}=2 \times 10^{-2}kg

So the volume of lead is,

v=\frac{m}{\rho} =\frac{2 \times 10^{-2}}{11300} = 0.00000177 m^3

v=1.77 \times 10^{-6}=1.8\times 10^{-6}m^3

So the volume of lead is v=1.8\times 10^{-6}m^3.

Answer:

12. 524 in³ (3 sig. fig.)   13. 2000 cm³ (3 sig. fig.)

Step-by-step explanation:

12. Volume of sphere = (4/3)πr³

= 500/3π

= 524 in³ (3 sig. fig.)

13. Volume of cylinder = πr²h

= 7²π(13)

= 637π

= 2000 cm³ (3 sig. fig.)

The ratio of dogs to cats in a shelter is 9:15.if the total number of cats and dogs is 96.how many dogs are there?
ch4aika [34]

There are 36 dogs in the shelter.

<h3>How to find the total number of dogs in the shelter?</h3>

The ratio of dogs to cats in the shelter is given as 9:15.

The total number of dogs and cats is given as 96.

Let the constant of proportionality be x.

The total number of dogs is 9x and the total number of cats is 15x.

This means that:

9x + 15x = 96

24x = 96

x = 4.

The total number of dogs in the shelter = 9 × 4

= 36

Therefore, we have found that there are 36 dogs in the shelter.
