Answer:
2.96 × 10^4 N
Explanation:
1 atm = 101325 N/m², pressure inside the airtight room = 1.02 atm, pressure outside due to hurricane = 0.91 atm
net pressure directed outward = P inside - P outside
net pressure = 1.02 - 0.91 = 0.11 atm
where 1 atm = 101325N/m²
0.11 atm = 0.11 × 101325 N/m² = 11145.75 N/m²
area of the square wall = l × l where l is the length of the wall in meters = 1.63 × 1.63 = 2.6569
net pressure = net force / area
make net force subject of the formula
net force = net pressure × area = 11145.75 × 2.6569 = 2.96 × 10 ^4 N
The answer is:
: Viruses produce toxins that damage cells.
If you neglect air resistance, then you can solve for the horizontal distance using the formula:
dx=vixt
Where:
dx = horizontal distance
vix = initial horizontal velocity
t = time in flight
Now you can see that you have all the given you need.
vix= 2km/h
t = 0.25 hours
We use hours because you need the units to be the same. So just plug that in your equation and you will have your answer:
dx = vixt
=(2km/h)(0.25h)
=0.5km
This means that the answer to your question is B.
