The Earth has always been a hospitable haven for life. ture or flase
Answer:
True and false at the same time
Explanation:
It is true that Earth is heaven for life but It's also hell for life because people suffer a lot and so does the Earth. Earth is a hell for life because of all the bullying, criticism, racism, sexism, and homophobic people. Life is a great thing to enjoy but with all the negative things that happened and keep happening in the world, it's a living hell for a life. The only good things are that you can explore and do things you never thought of doing before and you are ale=ways surrounded by people who love you and appreciate you for who you are but it's a 5-50 chance of you getting an opportunity like that.
I'm not a negative person it's just the ways that things are. I hope this answers your question!
Have a nice day! UwU

If the input force applied to one end of a first-class lever is 8 N, and the fulcrum is located 6 m away from the input force but 3 m away from the output force, what will be the resulting output force?
Answer:
16 N
Explanation:
The ratio of output force to the input force is called mechanical advantage of the lever. Also, the ratio of input arm distance to the output arm distance is called mechanical advantage of the lever.
We have,
Input force = 8 N
Input arm distance = 6 m
Output arm distance = 3 m
We need to find the resulting output force. So,
[tex]\dfrac{F_o}{8}=\dfrac{6}{3}\\\\F_o=16\ N[/tex]
So, the resulting output force is 16 N.
2 horizontal and parallel lines are intersected by 2 diagonal lines to form a triangle with exterior angles. The top angle of the triangle is 47 degrees. The exterior angle created by the right side of the triangle and the top horizontal line is x degrees. The bottom left angle of the triangle is y degrees. The exterior angle of the bottom right angle is z degrees above the horizontal line and 63 degrees below. Which statements about the diagram are true? Select three options. x = 63 y = 47 z = 117 x + y = 180 x + z = 180
Answer:
x = 63
z = 117
x + z = 180

The mass of a block is 12 g and the volume is 6 ml. Calculate the density of the block. (science)
Answer:
The answer is 2.0 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question
mass = 12 g
volume = 6 mL
We have
[tex]density = \frac{12}{6} \\ [/tex]
We have the final answer as
2.0 g/mLHope this helps you
Answer:
2.0 G/ML
Explanation:
Which of the following is a unit of density? = Mass / volume
A: liters per cubic gram
B:cubic meters
C:grams per cubic centimeter
D:square meters
Answer:
The correct answer is C.
Explanation:
To solve this problem, we should first recall possible units for mass and volume. Mass can be represented with units of grams, kilograms, etc. Volume has units of cubic meters, cubic centimeters, etc.
Therefore, since we know that density is mass divided by volume, the only answer that makes sense here is C. grams per cubic centimeter (where per signifies that grams are being divided by cubic centimeters).
Hope this helps!

Which of the following is a correctly written chemical equation that demonstrates the conservation of mass?
O A H2 + O2 + H2O
O B. Mg + HCl + H2 + MgCl2
C. KC 103 → KCl + O2
D. H2O + CO2 + H2CO3
Answer:
H₂O + CO₂ → H₂CO₃
Option D is correct.
Law of conservation of mass:
According to this law, mass can neither be created nor destroyed in a chemical equation.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
Now we will apply this law to given chemical equations:
A) H₂ + O₂ → H₂O
There are two H and two O atoms present on left side while on right side only one O and two H atoms are present so mass in not conserved. This option is incorrect.
B) Mg + HCl → H₂ + MgCl₂
In this equation one Mg, one H and one Cl atoms are present on left side of equation while on right side two H, one Mg and two chlorine atoms are present. This equation also not follow the law of conservation of mass.
C) KClO₃ → KCl + O₂
There are one K, one Cl and three O atoms are present on left side of equation while on right side one K one Cl and two oxygen atoms are present. This equation also not following the law of conservation of mass.
D) H₂O + CO₂ → H₂CO₃
There are two hydrogen, one carbon and three oxygen atoms are present on both side of equation thus, mass remain conserved. This option is correct.

Water and chemical elements move through cycles called biogeochemical cycles. Select the best way to explain biogeochemical cycles. a. When chemicals move from the atmosphere to a living organism. b. When a chemical moves from an organism to the atmosphere then back to an organism. c. When organisms move from an organism to the atmosphere then back to an organism.
Answer:
When a chemical moves from an organism to the atmosphere then back to an organism.
Explanation:
If we look at it closely, geology and chemistry play major roles in the process of movement and recycling of inorganic matter between living organisms and their environment. This has been called the biogeochemical cycle.
Biogeochemical cycles involve movement of chemical elements among the biotic and abiotic components of the environment; from atmosphere to land to sea, and from soils to plants.
A student performs an experiment to study how sound waves are transmitted by placing a ringing buzzer inside a bell jar and sealing the jar. The student then connects the bell jar to a vacuum pump to remove the air from inside of the jar. The table shows the student’s observations before and after removing the air from the bell jar.
What can be concluded from the experiment?
A. Sound waves are transverse waves.
B. Sound waves do not transmit through material mediums.
C. Sound waves do not carry energy when they are transmitted.
D. Sound waves transfer energy through the vibration of particles in mediums.
Answer:
D. Sound waves transfer energy through the vibration of particles in mediums.
Explanation:
It can be concluded from the experiment that sound waves will only propagate through vibration of particles in mediums.
The particles of the medium is the air.
This type of wave is called a mechanical wave. A mechanical wave is one that requires material medium for their propagation.Option A ; Sound waves are transverse waves; while this might be true or not, we cannot ascertain that through this experiment described.
Option B: this negates the conclusion that should be drawn from the experiment.
Option C: we cannot draw this sort of conclusion from such an experiment as this.
Therefore, the right choice is that, sound waves transfer energy through the vibration of particles in mediums.

Count the number of electrons in the innermost shell for helium, chlorine and potassium. How
many are there?
Answer:
Helium is 2 electrons
Chlorine is 7 electrons
Potassium is 1 electron

Cases of smallpox were very rare worldwide by 1980. Which most likely explains this? A. an increase in disease education B. a decrease in world travel C. an increase in number of vaccinations of young children D. a decrease in regulations on food preparation
Answer:
C.
Explanation:
The main reason for this decrease is an increase in the number of vaccinations of young children. The smallpox vaccine which was created in 1796 completely allows individuals to easily and quickly fight off the smallpox disease if they were to get it. By being able to fight the disease quickly and effectively it provides less time for the disease to affect another individual. Therefore, causing cases to decrease and become very rare as time goes on.
