Answer:
The answer is 5000 NExplanation:
The force acting on a body can be found by using the formula
force = mass × accelerationFrom the question
mass = 10 kg
acceleration = 500 m/s²
We have
force = 10 × 500
We have the final answer as
5000 NHope this helps you

If Maria winks exactly 5 times every minute while she is awake and she sleeps exactly 8 hours a day, how many times does Maria wink in a day? winks/day.
Answer:4,800
Explanation:
5 winks a minute, 60 minutes in an hour.
300 winks an hour, 16 hours a day.
4,800.
Answer:
The answer is 4,800 winks per day.
Explanation: There are 24 hours in a day, 24 minus the 8 hours shes asleep is 16. There are 60 minutes in an hour. 5 x 60 is 300. 300 winks an hour multiplied by the 16 hours she's awake is 4,800.
Compare and Contrast Heating and
Cooling curves.
Answer: Heating curves show how the temperature changes as a substance is heated up. Cooling curves are the opposite. They show how the temperature changes as a substance is cooled down. Just like heating curves, cooling curves have horizontal flat parts where the state changes from gas to liquid, or from liquid to solid.

If the average atomic mass is 39.948amu, which isotope is more abundant?
Answer:
It depends on which element you are talking about. I appears that no element has an average atomic mass of that number. So, for the question, if it assumes that there are two isomers with 39 amu and 40 amu, then the 40 amu one would be more abundant. But again, there are different possible isotopes and I can't tell what the question wants.

Why does oil float and not sink?
Answer:
because it has more density than water
Answer:
This is because oil is less dense than water and therefore it floats to the surface.

Billy is trying to figure out what type of wood to use for building a model boat. He has a block of wood with a volume of 8.0 cubic centimeters (cm3) and a mass of 4.0 grams (g). What is the density of the block of wood in g/cm3 to the nearest tenth?
A 0.5
B 2.0
C 4.0
D 32.0
Answer:
A; 0.5
Explanation:
To find the density, you have to do the Mass divided by the Volume; in this case, it's 8.0/4.0.
8/4 = 0.5
Bill Nye said the air pressure makes things what?
What is the mass of 15 ml of aluminum if the density is 2.70 g/ml?
Answer:
40.5g
Explanation:
desnity = mass/volume
2.7 = mass/15
mass = 2.7 x 15
mass = 40.5 g
Which substances from the simulation are more alkaline than water?
Which
Answer:
The substances more alkaline than water are;
1) Spit, 2) Blood, 3) Hand Soap, and 4) Drain Cleaner
Explanation:
The diagram in the simulation displays a list of liquid substances, arranged from bottom to top in the order of increasing alkalinity.
The ph of water is 7.0
The ph of spit (saliva) is between 6.2 and 7.6
The ph of blood is about 7.4
The ph of hand soap is between 9 and 10
The ph of drain cleaner is between 12 and 14.

What subatomic particle identifies any type of
atom?
Answer:
hope it helps..
Explanation:
Number of protons
More information: The atomic number is used to identify an element, and the atomic number is the number of protons in the nuclei of an element. Every element has its own unique number of protons, and therefore, atomic number.
Express the measurement using the appropriate SI prefix. For example, 10.72 x 103m is the same as 10.72 km because the “k” stands for 103
8.09 x 10-6g
(I got super stuck on this)
Answer:
[tex]10.72 \times 10 {}^{3} m = 10.72km \\ 8.09 \times 10 {}^{ - 6} g = 8.09 \times 10 {}^{ - 9} kg \\ \\ note : \\ to \: convert \: to \: \: k(units) \: you \: divide \: the \: value \: by \: {10}^{3} . \\ 5m \: to \: km \: will \: be : \\ \frac{5}{1000} km = {5 \times 10}^{ - 3} km[/tex]
Zinc has an average atomic mass of 65.37 amu. Jack is trying to figure out what the most abundant isotope of zinc is, but he doesn't have access to the internet, so the average atomic mass is the only information he has. Jack decides to made an educated guess as to the most abundant isotope of zinc by assuming there are only two isotopes of zinc. If Jack assumes there are only two isotopes of Zn, what he be most likely to decide is zinc's most abundant isotope?
Question 5 options:
Zinc-64
Zinc-65
Zinc-68
Zinc-66
Zinc's most abundant isotope : Zinc-65
Further explanationIsotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.
So Isotopes are elements that have the same Atomic Number (Proton)
Atomic mass is the average atomic mass of all its isotopes
In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu
Mass atom X = mass isotope 1 . % + mass isotope 2.%
To decide zinc's most abundant isotope, then choose the closest mass number
or we can check the difference with the average mass number, if the value is the smallest, then that isotope has the largest abundant
Zinc-64[tex]\tt \dfrac{65.37-64}{65.37}=0.021[/tex]
Zinc-65[tex]\tt \dfrac{65.37-65}{65.37}=0.005[/tex]
Zinc-68[tex]\tt \dfrac{68-65.37}{65.37}=0.04[/tex]
Zinc-66[tex]\tt \dfrac{66-65.37}{65.37}=0.009[/tex]
The closest = Zinc-65(the smallest)
