If a musical instrument such as trumpet or flute is "flat", should the pipe be lengthened or shortened? explain with at least 2 content related sentences.

If a musical instrument is flat, the pipe should be shortened.

Explanation:

When a musical instrument is out of tune, there can be two possibilities:

1. Flat.

2. Sharp.

A musical instrument, let's say a flat flute, is said to be flat when the pitch of its sound is lower than it is supposed to be.

A sharp flute, on the other hand means that the pitch of its sound is higher than it is supposed to be.

Now, in order to tune the flute we change its length using head-joint adjustments. This is because length is one factor in determining whether a flute plays a particular pitch in tune.

Increasing the length of the flute lowers the pitch while shortening the flute increases its pitch.

So, if a musical instrument is flat, its pitch is lower than it is supposed to be. To fix it, the pipe should be shortened.

force tends to be low and long diustance masses are high

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
