What is 4.7 times 10 to the negative third power (show your work)
Afina-wow [57]

Since we are working with an equation written in scientific notation and we are dealing with a negative exponent, we are going to divide 4.7 by 10 three times.

4.7 / 10 = 0.47

0.47 / 10 = 0.047

0.047 / 10 = 0.0047

Best of Luck!

Intermolecular forces in liquids are stronger than in gases but
Helga [31]

Answer:

Intermolecular forces in liquids are stronger than in gases but less that the forces in solids.

Step-by-step explanation:

The intermolecular forces in both liquids and solids have to be strong enough to hold the particles in the substances or objects together. Liquids and solids both have particles inside of them that barely have any room to move due to the strong hold that the intermolecular forces have between them. This is also with the help of the smaller amount of average kinetic energy between the molecules.

While liquids and solids both have greater intermolecular forces than the average amount of kinetic energy in the substances and objects, the particles  in liquids have room to freely move around unlike solids which have particles compacted so tightly that they have no room to move at all. For example, if you compare a cookie to the water inside of a glass of water, you can see that the water can move around and is flexible to any container that  you pour it in but the cooking does not move from it's solid form. The reasoning for this is because the water is a liquid and the particles are more flexible while the cookie is a solid and the particles cannot  be separated from each other. Therefore, the cookie isn't flexible.

The particles in gases are separated so far apart because the intermolecular forces in them are very weak compared to liquids and solids meaning they cannot hold the particles together.

Overall, intermolecular forces in liquids are stronger than in gases but weaker than the intermolecular forces in solids.

The arc made by a sector at center is 72 degrees . Given that the length of an arc is 44cm ,calculate the radius of the circle (
lesantik [10]

Given:

Central angle of a sector = 72 degrees

Intercepted arc length = 44 cm

To find:

The radius of the circle.

Solution:

We know that, the arc length is

s=2pi r\dfrac{\theta }{360^\circ}

Where, r is the radius of the circle, \theta is the central angle in degrees.

Putting s=44,\pi=3.14 and \theta = 72^\circ, we get

44=2(3.14)r\dfrac{72^\circ }{360^\circ}

44=6.28r(0.2)

44=1.256r

Divide both sides by 1.256.

\dfrac{44}{1.256}=r

35.031847=r

r=35.03

Therefore, the radius of the circle is about 35.03 cm.
