Answer:

See the answer below

Explanation:

Natural gas from different countries has a different percentage of hydrocarbons because they are formed from different biomass of organisms.

Natural gas is formed from decomposed organic matter that has been deposited millions of years ago. Layers of decomposing plants and animal matters buried deep in the ground experience intense heat and pressure and are eventually transformed after millions of years.

Different countries have different diversity of organisms. Hence, the organic matter that eventually transforms into natural gas for each country also differ. The implication is that the natural gas that would be formed in each country would be different. This is why natural gas from different countries may have different percentages of hydrocarbons.

Some gliders are launched from the ground by means of a winch, which rapidly reels in a towing cable attached to the glider. Wha

Answer:

P=627.47W

Explanation:

To solve this problem we have to take into account, that the work done by the winch is

$W=Fh$

the force, at least must equal the gravitational force

$F=Mg=(156kg)(9.8\frac{m}{s^2})=1258.8N$

with force the tension in the cable makes the winch go up.

The work done is

$W=(1258.8N)(58.0m)=73010.4J$

To calculate the power we need to know what is the time t. But first we have to compute the acceleration

The acceleration will be

$v_f^2=v_0+2ah\\a=\frac{v_f^2}{2h}=\frac{(24.9\frac{m}{s})}{2(58.0m)}=0.214\frac{m}{s^2}$

and the time t

$v_f=v_0+at\\t=\frac{v_f}{a}=116.35s$

The power will be

$P=\frac{W}{t}=\frac{73010.4J}{116.35s}=627.47W$

In most cases, what happens to a liquid when it cools?

kogti [31]

When liquid cools, both its density and volume increases. Therefore the answer to your question are #s 1 and 5. This is due to the fact that molecules which are compacted or pressed against each other form a solid, and when they start to cool-down the molecules start to break free from each other increasing the density of a liquid and the space that it occupies.

If you apply 150 newtons (N) of force to a solid brick wall for 5 seconds, but you do not move it, howmuch work have you done?A.

Lina20 [59]

Answer:

since there is no displacement, d = 0

Explanation:

hence work = f×d

= 150×0

= 0J
