Ω = 2000 rpm, initial angular speed.
t = 30 s, the time for the wheel to come to rest.
Calculate the angular deceleration, α.
w - αt = 0
(209.4395 rad/s) - (α rad/s²)*(30 s) = 0
α = 6.9813 rad/s²
The angular distance traveled, θ, is given by
ω² - 2αθ = 0
θ = ω²/(2α)
= 209.4395²/(2*6.9813)
= 3141.6 rad
The number of revolutions is
3141.6/(2π) = 500
Answer: 500 revolutions
To solve this exercise we must apply the concept of Flow as the measure given to determine the volume of a liquid flowing per unit of time, and that can be calculated through velocity and Area, mathematically this can be determined as
Q = Discharge of Flow
A = Cross sectional Area
Velocity
The area of the cross section of the capillary tube is
The total Area by this formula:
Where,
Stands for area of capillary
n = Stands for number of blood vessels
Finally replacing at our first equation,
Therefore the average speed, in centimeters per second, of blood flow through each capillary vessel is 1.66cm^3/s
I believe the formula you're looking for is force equals mass times acceleration. in this case the answer would be 3.
Answer:
1.1 m
Explanation:
PE = mgh
6.7 J = (0.62 kg) (9.8 m/s²) h
h = 1.1 m
It affects Metabolic Activity.
