Answer:
system
Explanation:
they are all put together as one, and they are a group
Amplitude is affected by the energy wave in the instrument. High energy wave means high amplitude and low energy wave means low amplitude.
<u>Explanation:</u>
The amplitude of a periodic variable is a measure of its change over a single period. There are various definitions of amplitude, which are all functions of the magnitude of the differences between the variable's extreme values.
The amount of energy carried by a wave is related to the amplitude of the wave. Amplitude of an instrument is directly affected by the wave of the energy in the instruments. High energy wave means high amplitude and low energy wave means low amplitude in the instrument.
Answer: Either of the two
Explanation:
Either of the two - the governed idle spring or the normal primary governor spring can be adjusted first.
The main function of the carburetor is to mix air with fuel.
A)Ep'=mgh=mgl(1-cosa).At the bottom of the swing Ep=0(reference level),so the potential energy as the child is just released is bigger than the potential energy at the bottom of the swing.;B)The speed of the child at the bottom of the swing-->v=√(2gh)=√[2gl(1-cosa)];C)I don't think that the tension does any work.
Answer: Phillipe wins the race
Explanation:
Given
Length of track=20 m
Velocity of Phillippe=2 m/s w.r.t sidewalk
Velocity of sidewalk=1.5 m/s
Rena velocity=2 m/s
Therefore absolute velocity of P is 2+1.5=3.5 m/s
Time taken by phillippe 
=5.714+10=15.714 s
Time taken by rena
as the time taken by phillippe is less than rena therefore Phillippe wins the race.
