Answer:
The pressure difference is 25.8kPa while the force exerted on the window by air pressure is 3.02 kN
Explanation:
Using the Bernoulli's equation

Here
- Pin-Pout is the pressure difference which is to be calculated.
- ρ is the density of air whose value is 1.29 kg/m^3
- vin is the velocity of air inside which is 0 m/s
- vout is the velocity of air outside which is 200 m/s
Substituting values in the above equation yields

So the pressure difference is 25.8kPa.
As force is given by

Here
- ΔP is the pressure difference calculated above
- A is the area of the window given as

Now force is

So the force exerted on the window by air pressure is 3.02 kN

Explanation:
It is what it is. and i took the edge test
Yes! with out the sun plants and animals wouldnt live right? therefore they get energey wich is passed on by food
Answer:
No.
Explanation:
Electromagnetic waves do not require a medium of matter to move through, electromagnetic waves are used in things like your cell phone and telecommunications.
Convert: 1km = 1000 m 200000 m * 0.01 s/m = 2000 s or 33 minutes and 20 seconds.
