What is the radius of an expanding circle at the moment when the rate of change of its area is numerically twice as large as the rate of change of its radius?
i dont know im only 5 A better answer: I assume you are taking differential calculus? A = (pi) R^2 dA/dt = 2 dR/dt cross multiply and find dA/dR = 2 dA/dR = 2 pi R = 2 R = 1/pi
Find a formula for Poiseuilles Law given that the rate of flow is proportional to the fourth power of the radius and Use k as the proportionality constant?
Rate of flow varies as R^4 where R is the radius or Rate of flow = (k) x (R^4)
How do you calculate the average transient rate?
Average Transient Rate
What is the relationship between flow rate pressure?
With the increase in flow rate the velocity of the fluid increases. and with the increase in velocity the pressure decreases, because there will be pressure drop (Refer Bernoulli's Theorm). So with increase in Flow rate the pressure decreases.
How can a school increase its average daily attendance rate?
Make Them Love School And All The Teachers In It .. Or! Make A Different Event EveryDay .. Or A Daily Event (Same)! ..Good Luck!
What will happen to flow rate if you increase the radius of a blood vessel?
If you increase the radius of a blood vessel, the flow rate of blood through that vessel will increase significantly. This is due to the principles of fluid dynamics, specifically Poiseuille's law, which states that flow rate is proportional to the fourth power of the radius. As the radius increases, resistance to flow decreases, allowing more blood to flow through the vessel with less pressure required. Consequently, a larger radius enhances overall blood circulation in the body.
The area of a circle is increasing at a uniform rate of 8cm square per second Calculate the rate of increase of the radius when the circumference of the circle is 96cm?
A = (pi)(r)2 (dA/dt) = (2(pi)(r)) * (dr/dt) (8) = (2(pi)(96)) * (dr/dt) (dr/dt) = (1) / (24(pi))
How would you rate your ping pong skills compared to others in your circle?
I would rate my ping pong skills as above average compared to others in my circle.
What is the effect that the flow radius change has on flow rate?
Increasing the flow radius generally leads to an increase in flow rate, as there is more cross-sectional area for fluid to flow through. Conversely, decreasing the flow radius usually results in a decrease in flow rate due to the reduction in available space for fluid passage.
How could adjust the afferent or efferent radius to compensate for the effect of reduced blood pressure on glomerular filtration rate?
increase afferent radius or decrease efferent radius depending on the degree of change in blood pressure
What changes would cause the fusion rate in the Suns core to increase?
Increase in the core temperature and decrease in the core radius.
How is flow rate affected when the right flow tube radius is kept constant 3.0mm and the left flow tube radius is modified either up or down?
If the flow tube radius on the left is increased, the flow rate will increase because a larger cross-sectional area allows for more fluid to pass through. Conversely, if the flow tube radius on the left is decreased, the flow rate will decrease as the smaller cross-sectional area restricts the flow of fluid. The flow rate is directly proportional to the radius of the flow tube.
What is the relationship between flow rate and radius size?
Flow rate= radius to the fourth power
What is one difference between the total fertility rate and the rate of natural increase, and can you describe it?
The main difference between the total fertility rate and the rate of natural increase is that the total fertility rate measures the average number of children a woman is expected to have in her lifetime, while the rate of natural increase calculates the difference between the birth rate and the death rate in a population.
Over the history of the human population the average increase rate of populations?
C. exponential
Do cows have an average pulse rate?
The average heart rate is 40 to 70 beats per minute.
What are linear taxes?
Linear taxes is the situation when the average tax rate is 20%. When this happens the tax rate will not increase with a higher income.
