Answer:
2π/[28 x (10^-3)]
Explanation:
Angular speed : ω=2π/T
T = 28ms = 28 x (10^-3) s
Angular speed = 2π/[28 x (10^-3)]
Answer:
110.87 dB
Explanation:
(I got it right on Acellus)
I= P/4(pi)r^2 = 60/4(pi)6.25^2
60/4(pi)6.25^2=0.12223
B=10log(I/Io)
B=10log(0.12223/1*10^-12) = 110.87 dB

Yolanda might put more items to the desk to make it heavier, requiring more force.
We need to learn more about the force acting on an object in order to locate the solution.
<h3>How can the force that is required to modify the motion be increased?</h3>
- We are aware that the word for force is,
F=ma
where m denotes the object's mass and an its acceleration
- There are two ways to increase the force required to alter the motion of the table.
- One is to increase the mass, and the other is to accelerate it more quickly.
- Otherwise, there will be a lot of friction between the surfaces, making it difficult to move without exerting a lot of force.
We can infer from this that Yolanda could add items to the desk to increase its mass, necessitating the use of additional force.

Answer:
The direction is downwards. This answer to this question is found from the applicatikn of flemings right hand rule. This rule uses the thumb, index finger and the middle finger in the direction of current force and the magnetic field.

Answer:
P = 0.6814 MPa
Explanation:
For this exercise we must use the Betuliano relation
P₁ + ½ ρ v₁² + ρ g y₁ = P₂ + ½ rho v₂² + rho g y₂
where we use the subscript 1 for the first pipe and the subscript 2 for the second pipe
indicate that the two pipes are at the same level therefore
y₁ = y₂
P₂ = P₁ + ½ ro (v₁² - v₂²)
let's calculate
P₂ = 13,785 10⁵ + ½ 997 (41,221² - 55,654²)
P₂ = (13.785 - 6.97) 105
P₂ = 6.814 10⁵ Pa
let's reduce to Mpa
P₂ = 6.814 10⁵ Pa (1 MPa / 10⁶ Pa)
P₂ = 6.814 10-1 MPa
P = 0.6814 MPa
