If the radius of a circle is doubled the how does that effect the area?
The area of the circle will be 4 times greater
What effect does tripling the radius and doubling the height of a cone have on the cone's volume?
the volume changes as radius squared and linear with height, so tripling radius and double of height gives 3 x 3 x 2 = 18 times more volume
What is 105 degrees on a radian unit circle?
105 deg = 1.8326 radians approx. The radius of the circle has no effect on the measurement of angles.
How do you get the diameter from the radius?
to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius
What is half of a diameter of a circle called?
The radius of the circle.
What was the FEV1 at a radius of 5.00 mm?
The FEV1 (%) at a radius of 5 mm is 73.9% (3541/4791 X 100%).
When surfactant is added what happens to the tidal volume?
FEV1 percentage decreases as the radius of the airway is decreased.
What creates a greater change in volume for a cylinder changing only the radius or changing only the height?
Changing the radius.
What is the difference between the FEV1 and peak expiratory flow?
FEV1 is the peak during the first second of exhalation only.
What does FEV1 stand for?
Forced expiratory volume
How much of an increase in FEV1 do you think is required for it to be considered significantly improved by the medication?
FEV1 is an index that is used to determine how much restrictive or obstructive lung disease is present in a person's lungs. If the FEV1 level is 70% or less then it is standard practice for medication to be given.
What happened to the FEV1 percent as the radius of the airways was decreased?
FEV 1 (%) will decrease as the airway radius is decreased. FEV 1 (%) is the amount of air that can be expelled from the lungs in one second during forced expiration. If the airway becomes smaller, then the resistance to airflow will increase and FEV 1 (%) will become lower.
Describe the effect on the area of a circle when the radius is doubled?
the radius is from the center of the circle to the edge so that's how you find the radius.
Can you lift a bronco 2 4 inches with out changing radius arms?
yes, you just need the drop brackets for the radius arms
What effects the cylinder more doubling the radius or doubling the height?
They both have the same effect on the surface area of the pipe, but the radius has more effect on its volume/capacity.
What is the effect of changig length or mass of pendulum on value of g?
Changing the length will increase its period. Changing the mass will have no effect.
Which variable had the strongest effect on fluid flow?
Radius
