Answer:
4992 J
Explanation:
Force, F = 39 N
Distance, s = 128 m
Work done = force x distance
W = 39 x 128
W = 4992 J
Thus, the work done is 4992 J.
For an individual to reduce his or her carbon footprint, they can:
- Reduce the use of automobile
- switch other renewable energy sources like solar energy
Hydrogen fuels are clean energy sources and should replace fossil fuels.
Carbon footprint should be regulated by law in order to reduce the amount of greenhouse gases.
<h3>What is a carbon footprint?</h3>
A carbon footprint is the measure of the total amount of greenhouse gases that are emitted into the atmosphere each year by an individual.
Greenhouse gases are responsible for global warming.
For an individual to reduce his or her carbon footprint, they can:
- Reduce the use of automobile
- switch other renewable energy sources like solar energy
Hydrogen fuels are able to replace fossil fuels as they are clean energy sources.
An individual's carbon footprint should be regulated by law in order to reduce the amount of greenhouse gases released.
In conclusion, greenhouse gases are responsible for global warming.

I'm not sure that's true ... we'd need to see some numbers.
But if it is true, it's the same reason why some places don't
want ladies to walk on their floors with high heels.
Pressure is (weight) divided by (area).
Pressure exerted
by a ballerina = (ballerina's weight)/(area of her toe on the floor)
Pressure exerted
by an elephant = (elephant's weight)/(area of 4 elephant feet)
Pressure exerted by
a lady in high heels = (lady's weight) / (area of 1 or 2 heels)
You can see that the greatest weight might not exert the greatest
pressure, and the smallest weight might not exert the smallest
pressure. The area is important, and it takes an awful lot of toes
or high heels to equal the area of one or more elephant's feet.
Answer:
the wind carries abrasive materials
Explanation:
such as sand and salt over time theses small particles slowly strip way at the land form sculpting it by eroding the softer layers first
