To address this problem, Boyle's Law must be applied, which states that the initial and final pressures and volumes are related as follows: Where, P₀ and V₀ represent the initial pressure and volume, while P and V refer to the final pressure and volume. The endpoint pressure in this scenario is atmospheric pressure. Thus, using the given equation, we can find the volume the lungs would occupy at the surface.
T= 24.5 feet per second. That’s the speed it attains just before hitting the ground.
Answer:
2.57 hours
Explanation:
Let t (in hours) represent the time it takes for Elsie to walk until they are separated by 25 miles. Since Steve starts 2 hours earlier, his time will be t + 2.
The distance covered by Steve heading north is 
The distance Elsie travels heading west is 
The separation between Steve and Elsie is

We can solve for t by squaring both sides.







Therefore, t = 2.57 or t = -4.13.
Since t cannot be negative, we select t = 2.57 hours.
Answer:
The number of photons emitted each second is
Explanation:
Let 'n' stand for the quantity of photons released by the bulb.
Provided Information:
The bulb radiates energy at a rate of 100 J per second (E).
Wavelength of emitted light is (λ) = 525 nm = 
The energy of a photon is calculated by:
Where,

Now, if we have 'n' photons, the total energy is equivalent to the energy of a single photon multiplied by the count of photons. Thus,

To express in terms of 'n', we find:

Insert the provided values and solve for 'n'. The resulting calculation yields

Consequently,
photons are discharged every second.
