The air pressure inside the balloon is: 0.1432 Pa
The formulas and procedures that we will use to solve this problem are:
Where:
- a = area of the sphere
- r = radius
- π = mathematical constant
- P = Pressure
- F = Force
- a = surface area
Information about the problem:
- r = 5.0 m
- F = 45 N
- 1 Pa = N/m²
- 1 N = kg * m/s²
- a=?
- P=?
Using the formula of the sphere area we get:
a = 4 * π * r²
a = 4 * 3.1416 * (5.0 m)²
a = 314.16 m²
Applying the pressure formula we get:
P = F/a
P = 45 N/314.16 m²
P = 0.1432 Pa
<h3>What is pressure?</h3>
It is a physical quantity that expresses the force applied on the area of a surface.

If you are referring to bacteria, the word "resistant" is applicable, as bacteria adapt to antibiotics by undergoing natural selection to enhance antibiotic-resistant genes.
If you are referring to humans or higher-order species, "grown tolerant" could be used to say that perhaps a certain antibiotic dosage is no longer as effective as it used to be and that a higher dosage is needed. "Acclimated" can also be used to say that an organism's body had to adjust to the exposure to a new, unfamiliar antibiotic.
Answer:
28500
Explanation:
Force equation - F = m * a
F = 950 * 30
F = 28500
The work of Brian mind interface is to learn that’s my guess lol
Answer:
D) 1000 m/s
Explanation:

You have the wavelength and frequency, you just need to solve for velocity. You can do this by multiplying each side of the equation by frequency.
Hope this helps.
