The answer would be A, because power is defined as the rate of doing work. Hence power = work / time then you obtain watts. Work is the product of force and displacement (distance). Hence in formula, w = F x s.
1 would use less energy. Please vote my answer brainliest! Thanks.
Answer:
In a given medium the velocity of a wave is always constant. This means that if the wavelength increases the frequency will decrease and if the frequency increases the wavelength will decrease.
Explanation:
= Wavelength
f = Frequency
Velocity
In a given medium the velocity of a wave is always constant. This means that if the wavelength increases the frequency will decrease and if the frequency increases the wavelength will decrease. This is true for any wave whether sound or electromagnetic.
On the moon you would weigh around 19 pounds!
When object absorbs energy then due to this energy it will have increase in it natural frequency
This increase in natural frequency will lead it to the increase in the amplitude of the object
Now when natural frequency of the object will match with the frequency of the wave that is absorbed by the object then this phenomenon is known as Resonance.
In resonance the amplitude of object will rise high and it will reach to its maximum limit.
so at condition
then in this condition it is known as resonance
