Exerts a force against it sliding down.
The average number of keys on a piano is 88.
The technical exercises are important in piano studying, because it strengthens the fingers, gives the fingers flexibility, and adds to your knowledge of the piano. The scales, etc... can be used as a warm-up routine. Studying the basics will help you understand the theory of the piano, and will aid you in mastering the circle of keys.

I played an octave on the piano.
88= piano keys
a.) the force exerted by the man is found by doing:Fnormal= mass(gravity)(sin30) - u(mass)(gravity)(cos30)(The "u" is the coefficient of friction)b.) the work done by the man is found by using the force we found in the question above and putting it into:W=FdMy coeffiecent of friction was 0.40 so my total force was 421.5NI just put it into W=421.5N(whateverdistanceIgiven)for example is it was 9cm: (9cm = 0.09m)W=421.5(0.09m) = 37.935Jc.) the work done by the friction force is solved the exact same way:Since my coefficient of friction = 0.40 my Force of Friction = 0.41(280kg)(9.8m/s2)(cos30) = 950.5NThen:W=Fd = 950.5N(0.09m) = 85.545Jd.) The work done by gravity: First, find force of gravity by: mass(gravity)(sin30) = 1372N, then just plug into W=Fd = 1372(0.09m) = 123.48Je.) the net work done on the piano = zeroSee: 123.48J - 85.545J = 37.935J !

No, "piano" is not plural. "Piano" is the singular form, and "pianos" is the plural form
on the piano
The spanish word for piano is actually, piano.
the piano sang beautifully when i played the piano
piano
The singular form of "piano" is "piano." The word doesn't change when referring to one instrument.
This is difficult to answer because "upright piano" is a standard and well-defined term "Student piano" is not. In 99% of cases, a "student" piano IS an upright piano.
