Answer:
The sheets move toward each other and the gap narrows
Explanation:
When two sheets are arranged or hanged in such a way, there is a small gap in between the two parallelly hanging sheets. This gap is filled by the surrounding air.
Now if we blow gently in between the gap of the two sheets, we will observe that the two sheets move towards each other and will come closer thereby narrowing the gap in between them.
This is because as we blow through the gap, partial vacuum is created in between the sheet for a short time. So this vacuum is filled by the air surrounding the two sheets thereby forcing the two sheets closer.
If a gun is sighted to hit targets that are at the same height as the gun and 85 m away at the same height, how low, as a positive number in meters, will the bullet hit if aimed directly at a target 180 m away
The muzzle velocity of the bullet is 275 m/s
Answer:
y = -1.1109 m
Explanation:
Range = 
range = 85 m
velocity = 275 m/s
g = 9.8 m/s²
If the bullet is aimed at a target 180 m, time required to travel 180 m with horizontal component will be;
t = 0.6546 sec
To determine, how low as a positive number in meters.
y = 
y = 0.9909 - 2.1018
y = -1.1109 m
D.
Potential energy is the correct answer since it's stuck but has the potential to create energy
Answer:
Explanation:
On each step the basilisk must provide an upward force that counters its weight, which is equal to W=mg. Since there are 4 steps in a given second, each step is performed every 0.25 seconds, so the impulse that each of the basilisk's steps provides will be 
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.
