A car accelerates from 20 m/s to 40 m/s in 4 seconds. What is the car’s acceleration?
Answer:
40 - 20 = 20
20/4 = 5m/s
The difference in velocity divided by the rate = acceleration.
Which of the three phases of matter solid liquid or gas has particles that are fast moving and independent of each other??? Also this is science class work

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!

Show how the limiting reactant is determined for 3.80 g of magnesium reacting with 12.5 g of oxygen.
Answer:
Magnesium is the limiting reactant.
Explanation:
The balanced reaction is:
2 Mg + O₂ ⇒ 2 MgO
By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following quantities participate in the reaction:
Mg: 2 molesO₂: 1 moleMgO: 2 molesBeing the molar mass:
Mg: 24.31 g/moleO₂: 32 g/moleMgO: 40.31 g/moleThen the following quantities of mass participate in the reaction:
Mg: 2 moles* 24.31 g/mole= 48.62 gO₂: 1 mole* 32 g/mole= 32 gMgO: 2 moles* 40.31 g/mole= 80.62 gThe limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.
To determine the limiting reagent, it is possible to use the reaction stoichiometry of the reaction. You can use a simple rule of three as follows: If by stoichiometry of the reaction 32 grams of oxygen react with 48.62 grams of magnesium, 12.5 g of oxygen will act with how much mass of magnesium?
[tex]mass of magnesium=\frac{12.5 g of oxygen*48.62 grams of magnesium}{32 grams of oxygen}[/tex]
mass of magnesium= 18.99 grams
But 18.99 grams of magnesium are not available, 3.80 molesgrams are available. Since you have less mass than you need to react with 12.5 grams of oxygen, magnesium will be the limiting reagent.
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

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.

Which of the following is an example of mutualism?
Answer:The relationship which is between bacteria and ungulates with the intestine is or good example of mutualism. Mutualism plays an important role in ecology. We can say that if we measure the exact fitness what we get as a benefit is a mutualistic relationship.example of a mutualistic relationship is that of the oxpecker (a kind of bird) and the rhinoceros or zebra. Oxpeckers land on rhinos or zebras and eat ticks and other parasites that live on their skin. The oxpeckers get food and the beasts get pest control.

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.

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.

BRAINLIEST ANSWER!!!Nitrogen has three occurring Isotopes: Nitrogen-13, Nitrogen-14, Nitrogen-15. Which isotope
is the most abundant?
Please also explain why:D
Answer:
N-14 is more abundant in nature because it is closest to the average atomic mass of 14.007. The average atomic mass is a weighted average which takes into account not only the mass but the abundance of a particular isotope.
