what is the density of a small block of wood with a mass of 35g and a volume of 70 cm3

Help plz

Answers

Answer:

The density of the wood is 0.5 g/cm³

Explanation:

To calculate density you need to use the formula D = M/V

D = Density

M = Mass (in grams)

V = Volume (in cm³ for solids and mL for liquids)

So, just plug in your given values: D = 35 g ÷ 70 cm³ = 0.5 g/cm³

Voila, you just calculated the density of that piece of wood!

49. Carbon-14 has a half-life of 5,730 years. If a sample contained 80 mg originally, how much
is left after 17,190 years?

50. The half-life of cobalt-60 is 5.26 years. If 100 grams are left after 15.78 years, how many
grams were in the original sample?

Answers

Answer:

i only found the 49, hope it still helps, mate

49. In this question (t½) of C-14 is 5730 years, which means that after 5730 years half of the sample would have decayed and half would be left as it is.

After 5730 years ( first half life) 70 /2 = 35 mg decays and 35 g remains left.

After another 5730 years ( two half lives or 11460 years) 35 /2 = 17.5mg decays and 17.5 g remains left .

After another 5730 years ( three half lives or 17190 years) 17.5 /2 = 8.75mg decays and 8.75g remains left.

after three half lives or 17190 years, 8.75 g of C-14 will be left.

You have learned that the atomic number of a chemical is the number of protons found in the nucleus. Atomic numbers can be used to find the number of neutrons and electrons in an atom. In this project, you will practice atomic mass and atomic mass number calculation as well as fill out a chart using the periodic table. Don’t forget to read through the rubric below, so you will know what you will be graded on. When you are ready, upload it replacing the “Lastname” in the saved document name with your last name.
Part I:
The atomic number of the sodium atom is 11. The atomic mass number can be estimated by rounding the atomic mass to 23. From this information, you can find the number of neutrons: 11 protons plus how many neutrons equals a mass number of 23? The number of neutrons would have to be the difference between 23 and 11, which is 12. This fact can be restated this way: 11 protons plus 12 neutrons equals a mass number of 23. For every proton in the nucleus, an electron revolves around the nucleus. Since 11 protons are in sodium, 11 electrons must be in sodium.
Using this information and the Periodic Table from lesson titled Periodic Table fill in the chart below.

How does Earth's rotation affect ocean currents?

Lesson 2.09

Question 9 options:

It causes them to flow in a curved path


It has no affect


It causes them to flow from east to west


It causes them to flow from north to south

Answers

Answer:

Our planet's rotation produces a force on all bodies moving relative to theEarth. ... The force, called the "Coriolis effect," causes the direction of winds and ocean currents to be deflected.

Explanation:

Earth's rotation affect ocean currents because: A. It causes them to flow in a curved path.

What is Earth rotation?

Earth rotation can be defined as the amount of time that is taken by planet Earth to complete its spinning movement about an orbital axis.

This ultimately implies that, Earth rotation refers to the time taken by earth to rotate once on its axis. Also, a spinning movement of the Earth on its axis takes approximately 24 hours to complete with respect to the Sun and it result in an effect called Coriolis.

In conclusion, Earth's rotation affect ocean currents because it causes them to flow in a curved path due to Coriolis effect.

What is unique about the metal mercury?

Answers

Mercury is the only metal that is a liquid at standard temperature and pressure.
—Mercury has a unique electron configuration which strongly resists removal of an electron, making it behave similarly to noble gas elements.
—As a result, mercury forms weak bonds and is a liquid at room temperature.
—Mercury dissolves to form amalgams with gold, zinc, and many other metals.

Are two clear liquids mix to create a “chunky” solid a chemical of physical change? Why?

Answers

Answer:

Well i know that a chemical change is somthing that can not be undone.

This however is a physical change let me explain.

Even though you mixed two chemicals together to create a new substance does NOT mean it is a chemical change. This however is kinda like a water. You can turn water into a ice cube that does not mean it changed what the water is made out of it just changed the form of the water. Kinda like this. A chemical change would be an example of buring a log once that log has turned into ashs it will never be the log it was before.
