The Tennessee Valley Authority's coal-fired Kingston plant in Tennessee generates 10 billion kilowatt-hours a year by burning 13,000 metric tons of coal a day, supplying electricity to almost 700,000 homes. If all of the 7.7 billion metric tons of coal consumed worldwide in 2015 was converted to electricity, it would have produced approximately _____ billion kilowatt-hours of electricity. Assume the same efficiency as the Kingston plant.
Answer:
Approximately 16228 billion kilowatt-hours of electricity will be produced.
Explanation:
According to the statement, yearly energy production is directly proportional to amount of carbon to be burnt. Then, we proceed to estimate the yearly energy production from worldwide coal consumption ([tex]E[/tex]), in kilowatt-hours, by simple rule of three:
[tex]E = 10\times 10^{9}\,kWh\times \frac{7.7\times 10^{9}\,ton}{4.745\times 10^{6}\,ton}[/tex]
[tex]E = 16228\times 10^{9}\,kWh[/tex]
Approximately 16228 billion kilowatt-hours of electricity will be produced.

HELP ME PLSSS What are the possible genotypes
of the F, offspring? What are the
possible phenotypes of the F,
offspring?
Answer:
the answer is b i think
Answer:Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism.
Explanation:
The phenotype is the trait those genes express. ... Looking at the possible offspring, each box (or possible offspring) has two copies of the dominant gene. This means there is a 100% chance of the offspring having brown eyes, or being BB. It's important to note here that each box represents a possible offspring.

4. Predicting What would have happened, in terms of thermal energy transfer, if the water temperature had originally been10.0°C? Explain your reasoning.
Context:Background InformationThe quantity of energy transferred by heat from a body depends on anumber of physical properties of the body and its surroundings. For a given substance, the rate at which thermal energy is transferred by conduction depends on temperature difference, cross-sectional area,and a thermal conductivity constant that is unique to the substance.By choosing one of these properties as a manipulated variable and making the other properties controlled variables, the effect of the manipulated variable on thermal conduction can be determined experimentally.In this investigation, you will study the rates of cooling of three containers of water of equal volume but different surface area.

If a species experiences a helpful mutation, like camouflage, explain how that mutation would help the species to better survive and flourish. Again, be sure to explain how and why that mutation would be helpful.
Help me please I need it fast, I’ll give b if correct!!!
Links = reported
Wrong answer= report (depends if it’s a whole different answer)
Answer:
A helpful mutation like camoflage would immensely help a species survive and flourish. The reason being the appliances of such a mutation. Camoflage is one of the most apllicable of abilities. It can be used as a defense mechanism, to hide in plain sight, it can be used offensively to avoid being seen while hunting and it can even be used as a form of communication between the species. All of these appliances would greatly benefit the species and would most definitely help it survive and flourish.

Write a one paragraph essay about the importance of the different biomolecules in our life.
Answer:
#tried my bestt
do mark me as brainlist
Biomolecules are made by living organisms and they are made because they are functional. Biomolecules, or at least most of them, do not exist outside of living organisms because they are too complex to be created by chance chemical collisions. The odds of a single average sized protein to form by chance has been calculated at 1 out 10 to the 77th power. Biomolecules REQUIRE intelligent agency to form them.
The four main purposes of biomolecules are:
1. Structure (some proteins)
2. Energy storage and release (carbohydrates)
3. Protective layers (lipids)
4. Information storage and communication (DNA, RNA, endocrines of numerous various types and manipulated molecules, such as fatty acids)

A rocket experiences a 45,000 N force as it accelerates at 30 m/s/s. What is the mass of the rocket?
Answer:
15,00kg
Explanation:
here's your solution
=> force = 45,000N
=> acceleration = 30m/s^2
=> mass = ?
=> Mass = force/acceleration
=> mass = 45,000/30
=> mass = 15,00kg

Consider two walls, A and B, with the same surface areas and the same temperature drops across their thicknesses. The ratio of their thermal conductivities is kA/kB=4 and the ratio of the wall thickness is LA/LB=2. The ratio of heat transfer rates through the walls qA/qB is:
(a) 0.5
(b) 1
(c) 2
(d) 4
(e) 8
(f) None of them
Answer:
(c) 2
Explanation:
Heat transfer across the walls due to conduction is given by:
[tex]q = -KA\frac{\Delta T}{L}[/tex]
where,
q = heat transfer rate
K = thermal conductivity
A = Area
ΔT = change in temperature
L = thickness
For wall A:
[tex]q_A = -K_AA\frac{\Delta T}{L_A}[/tex]
For wall B:
[tex]q_B = -K_BA\frac{\Delta T}{L_B}[/tex]
Because the change of temperature and area of walls are the same. Dividing both terms:
[tex]\frac{q_A}{q_B} = \frac{\frac{K_A}{L_A} }{\frac{K_B}{L_B}}\\\\ \frac{q_A}{q_B} =\frac{\frac{K_A}{K_B} }{\frac{L_A}{L_B}}[/tex]
using values given in the question:
[tex]\frac{q_A}{q_B} = \frac{4}{2}\\\\\frac{q_A}{q_B} = 2[/tex]
Therefore, the correct answer is:
(c) 2

Answer:
primary voltage/secondary voltage = number of turns on primary coil/number of turns on secondary coil
V1/V2= N1/N2
1.5/5 = 150/N2
0.3 = 150/N2
N2= 150/0.3
N2 = 500

A 31 kg child is traveling at 4 m/s while sledding down a hill. What is the child's kinetic energy at the bottom of the hill?
Answer:
K.E = 248 J
Explanation:
Since the child is travelling at a given velocity. The kinetic energy of the child down the hill can be given by the following formula:
[tex]K.E = \frac{1}{2}mv^2\\[/tex]
where,
m = mass of the child = 31 kg
v = velocity of the child = 4 m/s
Therefore,
[tex]K.E = \frac{1}{2}(31\ kg)(4\ m/s)^2\\[/tex]
K.E = 248 J
