Answer:
Atelectasis
Explanation:
Atelectasis is defined as the partial or completely collapsion of lungs, it is caused because of the collapse of tiny sacs of lungs or with the possibility, that these space is filled by the alveolar fluid.
Atelectasis is the condition in which the surface area of the alveolar is collapse, this can be caused due to the absence of surfactants. This condition will result in decrease or reduction of gas exchange.
Answer:
1. 2 N to the left
2. To the left.
Explanation:
1. Determination of the net force.
Force applied to the right (Fᵣ) = 18 N
Force applied to the left (Fₗ) = 20 N
Net force (Fₙ) =?
The net force acting on the book can be obtained as follow:
Fₙ = Fₗ – Fᵣ
Fₙ = 20 – 18
Fₙ = 2 N to the left
Thus, the net force acting on the book is 2 N to the left
2. Determination of the direction.
From 1 above, the net force acting on the book is 2 N to the left. This simply means that the book will move to the left direction.
angular vel to tangential vel
v=r omega
v = 56 x 100/60 x 2 pi
v = 56x5/3x6
v=560m/s as estimate

The estimated density of the golf ball is 170 kg/m³
What is density?
Density is the ratio as Mass per unit Volume.
In displacement method,
First , we measuring the volume of water displaced by an object which tell us the volume of the object then we will use the physical balance to determine its mass.
Then calculate the density by dividing the mass by the volume.
Here, D = m/V
By displacement method , the estimated volume of golf ball is 100 cm³ and estimated mass is 600 g
Then ,
Density = 100 cm³ / 600 g = 0. 17 g/ cm³ = 170 kg/m³
So the estimated density of golf ball is 170 kg/m³

Wavelengths of light are emitted when an electron is coming from an energized state back to its initial state. The energy that is omitted comes in the form of the wavelength. I'm not completely sure if this is totally the way to say it, but it is what I remember from chem last year.
