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

WILL GIVE BRAINLIEST AND 20 POINTS How many grams are in 2.36 L of neon gas
Answer:
2.088464 grams.
Explanation:
The density of neon is 0.9002 g/L. Multiplying this value by the number of liters gives how many grams of neon it contains.
0.9002(2.32) = 2.088464

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
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 3 things drive the pressure of a gas up
Answer:
Density of the GasExplanation:
More molecules mean more hits against the container walls. Increasing the number of particles means you have increased the density of the gas. This third factor is part of the ideal gas law, which explains how these three factors -- temperature, volume and density -- interact with each other.

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?
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.

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