If the radius of a circle decreased would the area decrease?
Yes. The area is proportional to the square of the radius. If the radius becomes smaller, so does the area.
When the diameter of a sphere is decreased by 25 percent by what per cent does its curved surface area decrease?
Surface area, S.A., of a sphere with radius r equals to 4pir2.Since the diameter is decreased by 25%, the radius is also decreased by 25%.That is r - 0.25r = 0.75r.So that S.A. = 4pi(0.75r)2 = 2.25pir2
What happen to the number of births in the two years prior to 1946?
decreased
Who invented frequency distribution?
Nobody invented frequency distribution. Events happen, as is the nature of events. Some events can have different outcomes and a frequency distribution is simply the proportion of times that these different outcomes happen (empirical freq distrib) or are expected to happen based on scientific laws (theoretical freq distrib).
How is the wavelength related to frequency for waves moving at a constant speed?
Whatever the wavelength and frequency happen to be, their product is always equal to the speed.
What will happen to the wavelength if the frequency is decreased?
the wave length will increase
When the radius is increased does the period of rotation increased or decreased?
Generally decreased.
How did changing the radius effect FEV1?
Decreased the FEV1 %
What will you hear if the frequency of the sound is decreased?
A lower note.
What happens to resistance if radius of a wire is decreased by a factor of 3?
resistance is inversily proportional to squaire of radius of wire.
If the radius of a circle decreased would the area decrease?
Yes. The area is proportional to the square of the radius. If the radius becomes smaller, so does the area.
What happened to the wavelength and frequency when you increased the rate at which the spring toy moved left and right?
The wavelength decreased and the frequency increased.
What is the Effect of reduced the frequency from supply frequency on induction motor?
The main difference will be the motor's torque will be decreased, potentially making it undersized for its' purpose. The motor's speed will also be decreased since n=(120f)/P.

When surfactant is added what happens to the tidal volume?
FEV1 percentage decreases as the radius of the airway is decreased.
Why does the forced expiratory volume percentage decrease as the radius of the airways is decreased?
Reducing the radius of the airways will affect the capacity of the lungs to exhale the maximum amount of air
Name at least two ways that thermal energy in air can be decreased?
The thermal energy in air could be decreased by cooling it by contact with a chill plate; or if the air pressure were decreased, the frequency of collision would decrease.
