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?
If the frequency is decreased, the wavelength will increase. This is because the wavelength and frequency of a wave are inversely proportional to each other according to the wave equation λ = c/f, where λ is the wavelength, c is the speed of light, and f is the frequency.
How did changing the radius effect FEV1?
Decreased the FEV1 %
What will you hear if the frequency of a sound id decreased?
If the frequency of a sound is decreased, the pitch of the sound will become lower. This means that the sound will sound deeper or lower in tone.
What will you hear if the frequency of the sound is decreased?
A lower note.
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 radius is increased does the period of rotation increased or decreased?
When the radius is increased, the period of rotation will increase. This is because a larger radius means the object has to travel a greater distance in the same amount of time, leading to a longer period of rotation.
How does pitch lowness of the tone change when frequency is increased or decreased?
When frequency is increased, the pitch of the tone becomes higher. This is because higher frequency vibrations are perceived as higher pitched sounds. On the other hand, when frequency is decreased, the pitch of the tone becomes lower. This is because lower frequency vibrations are perceived as lower pitched sounds.
What happens to the wavelength of a wave if the frequency is decreased?
If the frequency of a wave is decreased, the wavelength of the wave will increase. This is because frequency and wavelength are inversely related in a wave, meaning that as one decreases, the other increases.
What happens to resistance if radius of a wire is decreased by a factor of 3?
If the radius of a wire is decreased by a factor of 3, the resistance of the wire will increase by a factor of 9. This is because resistance is inversely proportional to the cross-sectional area of the wire, which is proportional to the square of the radius. So, decreasing the radius by a factor of 3 will result in the area decreasing by a factor of 9, leading to a 9-fold increase in resistance.
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 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
How does the wavelength of a light wave change if the frequency is decreased by a factor of 2?
If the frequency of the light wave is decreased by a factor of 2, the wavelength will double. This is because the speed of light remains constant in a given medium, so as frequency decreases (and energy decreases), wavelength increases to maintain the speed of light.
