Earth’s tilt from its axis.
For explanation:
The angle in which Earth is at is 23.5°. This causes its tilt which affects how the Sun’s light hits Earth
<h2>Answer:</h2>
The part of the electromagnetic spectrum usually used for communication is of radio waves, infrared waves and microwaves.
But most common waves used in communication are radio waves.
<h3>Explanation:</h3>
- Radio waves are used to transmit television and radio programmes.
- While microwaves are used for mobile phones and Wi-Fi.
- Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light.
- Radio waves have frequencies as high as 300 gigahertz (GHz) to as low as 30 hertz (Hz).
Answer:
1) Pm₂ = 1.9 10⁴ Pa
, b) P_feet = 5.4 10⁴ Pa
, c) Pm₄ = 4.4 10⁴ Pa
Explanation:
a) Pressure can be found using Bernoulli's equation
P₁ + ½ rho v₁² + rho g y₁ = P₂ + ½ rho v₂² + rgo g y₂
The amount of blood that runs through the constant system, all the blood that reaches the brain leaves it, so we can assume that the speed of entry and exit of the total blood is the same. In this case the equation is
P₁-P₂ = rgo h (y₂-y₁)
The gauge pressure is
Pm = P₁ -P₂
Pm₂ = 1.06 10³ 9.8 1.83
Pm₂ = 19 10³ Pa
Pm₂ = 1.9 10⁴ Pa
The pressure in the heart is
Pm₁ = 246 torr (1,013 10⁵ Pa / 760 torr) = 3,279 10⁴ Pa
Therefore the gauge pressure is an order of magnitude less
Total or absolute pressure is
Pm₂ = P_heart - P_brain
P_brain = P_heart - Pm₂
P brain = 3,279 10⁴ - 1.9 10⁴
P brain = 1.4 104 Pa
b) on the feet
Pm₃ = rho g y₃
y = 2.04 m
Pm₃ = 1.06 10³ 9.8 2.04
Pm₃ = 21 10³ Pa
Pm₃ = 2.1 10⁴ Pa
Total pressure
Pm₃ = P_feet + P_heart
P_feet = Pm₃ + P_heart
P_feet = 3,279 10⁴ + 2.1 10⁴
P_feet = 5.4 10⁴ Pa
c) If you lower your head the height change is
h = 1.83 +2.04
h = 4.23 m
Pm₄ = 1.06 10³ 9.8 4.23
Pm₄ = 4.4 10⁴ Pa
Answer:
The average power of this wave is 5.42 Watts.
Explanation:
The transverse wave on a rope is given by :
The general equation of the transverse wave is :
Let the mass per unit length of the rope is 0.0500 kg/m.
The average power of this wave is given by :
Where
is the linear mass density,
A = 0.75 cm = 0.0075 m
Propagation constant,
Angular velocity,
f = 125 Hz
Velocity,
Average power of the wave is :
P = 5.42 Watts
So, the average power of this wave is 5.42 Watts. Hence, this is the required solution.
