Power consumed by blow dryer is given as
here supply voltage is given as
current rating of blow dryer is given as
Part b)
Power consumed by vacuum cleaner is given as
here supply voltage is given as
current rating of vacuum cleaner is given as
Part c)
Energy consumed in a given interval of time is given as
now we have to find the ratio of energy consumed in time interval of 11 minutes
so we have
now we have
C. I took the test...........
Answer:
As the string vibrates, it "moves" the particles in the air, generating what we know as a soundwave.
Because this soundwave is generated by the wave-like motion of the string, makes sense that the soundwave will have some characteristics in common with the standing wave on the guitar string. This means that both waves will have the same normal modes. (So if the principal mode of the vibrating string has a frequency of 440hz, to soundwave also will have that main frequency, and we will hear an A). You can hear almost all the normal modes when you pluck a guitar string, particularly in music, these are called "overtones" or "harmonics"
Answer: tactile (Meissener) corpuscle.
Hope this helps.
Statements 2 and 4 are correct. The velocity changes because the initial velocity is zero and each second they gain 9.8 m/s of velocity, which is the constant acceleration. Because there is no air resistance, they will land at the same time, and gravity acts equally upon both objects, so the velocity of both metal balls should always be the same.
