Your answer is, B.

What is Coal?

Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands —called coal forests —that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian) and Permian times.

3 stages of how coal formed

After the formation of peat, it will with the lapse of geological time be transformed into different types of coal under the conditions obtaining at depths within the crust.

Peat is changed into lignite, lignite into bituminous coal and bituminous coal into Anthracite.

The series peat-Lignite-Bituminous-Anthracite.

Thus, option b is your answer.

Why is fusion important?

Sonja [21]

Abundant energy: Fusing atoms together in a controlled way releases nearly four million times more energy than a chemical reaction such as the burning of coal, oil or gas and four times as much as nuclear fission reactions (at equal mass)

Which properties of a lava lamp are important to remember when modeling convection?

Luba_88 [7]

Important thing when making a lava lamp are the two liquids with different density so that it would not mix and that it would expand when heated. The movement of the orange liquid is called convection. if you will not heat the orange one, it till just stay on the stop and not go under tha water.

A hot air balloon competition requires a balloonist to drop a ribbon onto a target on the ground. Initially the hot air balloon

Tpy6a [65]

Answer:

The answer is 3.48 seconds

Explanation:

The kinematic equation

y= y0+V0*t+1/2*a*(t*t)

-50=0+(0)t+1/2(-9.8)*(t*t)

t=3.194 seconds

During ribbons ball,

x=x0+ Vt+1/2*a*(t*t)

x= 0+(15)*(3.194)+1/2*(0)* (3.194*3.194)

x= 47.9157m

So, distance (D) = 100-47.9157= 52.084m

52.084m=0+15(t)+1/2*(0)(t*t)

t=52.084/15=3.472286= 3.48seconds
