Describe briefly how fossil fuels were formed

Answers

Answer 1
Answer: Fossil fuels are formed by organic remains that have been buried under rock. "Organic remains" can include animals and plants (think of oil and dinosaurs).
Answer 2
Answer: Fossil fuels were formed by the compression of dead plants and animals due to high pressure and temperature.
Some fossil fuels are coal, petroleum and natural gas

A circuit contains a 12 volt battery and two 3- ohm bulbs in a series. What is the voltage across each branch?

Answers

If the bulbs are in series, then there are no 'branches' ... just
a single current path all the way around.

If the two bulbs have equal resistance, then no matter what their
actual resistance is, the supply voltage will divide equally between
them ... 6 volts across each bulb.

A typical carbon atom has six protons, six neutrons, and six electrons. Which of these has the least amount of mass?A) one Proton
B) one Neutron
C) six Electrons
D) These masses are too tiny to measure

Answers


One proton or one neutron have very close to the same mass.

Their mass is about the same as the mass of 1,840 electrons !
So six electrons have roughly the same mass as 0.0033 of one
proton or one neutron.

Yes, these masses are very tiny.  None of them was ever measured
until the 20th Century.  But all of them have now been measured,
very precisely and accurately.  This is very impressive, and should
give us a lot of admiration for scientists of the past hundred years.
It would be very interesting to look around online and find out
how they did it.

a pelican flies at a speed of 52 km/h for 0.25 hours . how many miles does the pelican travel ? the conversion factor is 1.6 km/h = 1.0 mph

Answers

The pelican traveled 487.5 miles.

First I divided 52 by 1.6, i got 32.5, then found out how many minutes in 0.25 hour, which is 15 minute. Finally I times 32.5 and 15 together to get my finally answer.

Why does earth have the youngest surface of all the terrestrial planets today?

Answers

Answer:

Its the biggest terrestrial planet as the result of the interior being not able to cool down that much.

its rotates rapidly

Explanation:

the earth planet is not close to the sun,which puts it in the advantage of not loosing water.

When an electric current is passed through water during the process of electrolysis two gases are formed one gas has a boiling point of -183 c and the other has a boiling point of -253 change or a chemical change occurred explain had a physical change or a chemicial change occurred explain?

Answers

There is a chemical change because the liquid water, after passing an electric current, produces hydrogen and oxygen gases. This is a reaction. The molecular component of eater has been broken down into two. These two gases have different structures compared to water.

Verify the identity. Show your work.

cot θ ∙ sec θ = csc θ

Answers

To verify the identity, we can make use of the basic trigonometric identities:
cot θ = cos θ / sin θ 
sec θ = 1 / cos θ
csc θ = 1 / sin θ

Using these identities:
cot θ ∙ sec θ = (cos θ / sin θ ) ( 1 / cos θ)

We can cancel out cos θ, leaving us with
cot θ ∙ sec θ = 1 / sin θ
cot θ ∙ sec θ = = csc θ

Imagine two billiard balls on a pool table. Ball A has a mass of 2 kilograms and ball B has a mass of 3 kilograms. The initial velocity of ball A is 9 meters per second to the right, and the initial velocity of the ball B is 6 meters per second to the left. The final velocity of ball A is 9 meters per second to the left, while the final velocity of ball B is 6 meters per second to the right. 1. Explain what happens to each ball after the collision. Why do you think this occurs? Which of Newton’s laws does this represent? 2. What can you say about the total momentum before and after the collision? 3. What do you think would happen to the velocity of each ball after the collision if the masses and initial velocities of each ball were the same? 4. The mass of ball A is 10 kilograms and the mass of ball B is 5 kilograms. If the initial velocity is set to 3 meters per second for each ball, what is the final velocity of ball B if the final velocity of ball A is 2 meters per second? Use the elastic collision equation to find the final velocity of ball B. Assume ball A initially moves from right to left and ball B moves in the opposite direction. Identify each mass, velocity, and unknown. Show your work, including units, and indicate the direction of ball B in your answer. 5. If the mass of each ball were the same, but the velocity of ball A were twice as much as ball B, what do you think would happen to the final velocity of each ball after the collision? To answer this question, create a hypothesis in the form of an if-then statement. The “if” is the independent variable, or the thing that is being changed. The “then” is the dependent variable, or what you will measure as the outcome. (Please show your work if you can)
