What type of heat transfer happens in the Inner Core?

Answer:

P

Explanation:

Answer:

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\ [/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{1.23\times {10}^{18} }{6.02 \times {10}^{23} } \\ = 0.00002043...[/tex]

We have the final answer as

Hope this helps you

Answer:

30 feet /second

Explanation:

60 feet/ 2 sec = 30 feet/sec

Answer:

30 feet/sec

Explanation:

Average speed = distance / time (distance divided by time)

Average speed = 60 feet / 2 seconds

Average speed = 30 feet/sec

So the anverage speed is 30 feet per second

Option B

6 g/cm³

Hi there !

density formula

d = m/V

V = 33.0ml - 25.0ml = 8.0 ml = 8 cm³

m = 48.0 g

replace

d = 48g/8cm³ = 6 g/cm³

Good luck !

Answer:

16.68 m/s

Explanation:

The following data were obtained from the question:

Height (h) = 14.2 m

Initial Velocity (u) = 0 m/s

Final velocity (v) =?

Thus, the velocity (v) with which the ball hit the ground can be obtained as follow:

v² = u² + 2gh

NOTE: the acceleration due to gravity (g) = 9.8 m/s²

v² = u² + 2gh

v² = 0² + 2 × 9.8 × 14.2

v² = 0 + 278.32

v² = 278.32

Take the square root of both side

v = √278.32

v = 16.68 m/s

Therefore, the velocity with which the ball hit the ground is 16.68 m/s

Explanation:

This is a pretty straightforward example of how to sue Avogadro's number to figure out the number of molecules present in a given sample.

In your case, the sample is said to contain  

2.50

moles of water. Now, a mole is simply a very, very large collection of molecules. In order to have  

1

mole of a molecular compound you need your sample to contain  

6.022

molecules of that compound.

The water molecules are in a block of ice containing 0.750 mole of water. The number of water molecule is 4.52 x 10²³molecules.

Molecules are defined as a group of two or more atoms that together create the lowest recognizable unit into which a pure material can be separated while retaining its makeup and chemical qualities.

It can also be defined as a group of two or more atoms held together by attractive forces called as chemical bonds.

There are mainly three types of molecule.

1 mole of water molecules = 6.022 x 10²³ molecules

So, 0.750 mole of molecules = 6.022 x 10²³ x 0.750

                                                 = 4.52 x 10²³ molecules

Thus, the water molecules are in a block of ice containing 0.750 mole of water. The number of water molecule is 4.52 x 10²³molecules.
