Answer:
1. The respiratory system functions when our involuntary nervous system sends impulses to the muscles in the diaphragm; thereby, causing the lungs to expand and contract.
2. The respiratory system oxygenates the blood which is vital for bodily function as oxygenated blood is carried from your lungs to the left side of your heart, to be circulated throughout the body. Furthermore deoxygenated blood is carried back to the right side of your heart to get oxygenated once more.
3. The other body systems that are crucial for the lungs to function are the nervous system and the muscular system.
4. without the raspatory system the body wouldn't receive any oxygen and the brain would slowly die. therefore, without the brain the heart would stop functioning and atrophy etc.
Explanation:
Answer:
55.8 m/s
Explanation:
= Actual frequency of sound emitted by car
= frequency observed when the car moves = 
= Speed of sound = 343 m/s
= Speed of car
Frequency observed is given as
Answer:
Explanation:
Given data
Frequency f=90 Hz
To find
First three overtones of bassoon
Solution
The fundamental frequency of bassoon is found by substituting n=1 in below equation
f=v/λ=nv/2L
The first overtone of bassoon is found by substituting n=2
So
The second overtone of bassoon is found by substituting n=3
So
The third overtone of bassoon is found by substituting n=4
So
Answer:
B
Explanation:
Remark
If, when it reaches its maximum height where the PE is the greatest, that the maximum energy is when the ball is first kicked. That would mean its starting energy is 10 Joules.
Formula
KE = 1/2 m v^2
Givens
KE = 10 J
m = 0.2 kg
v = ?
Solution
10 = 1/2 * 0.2 * v^2
10 * 2 = 0.2 * v^2
20 = 0.2 * v^2
20/0.2 = v^2
100 = v^2
v = 10 m/s
Positive terminal with Positive terminal. The negative terminal should be connected to the car chassis.
