To develop this problem we will apply Newton's laws regarding gravitational forces, both in space and on earth. From finding this relationship, leaving the variable of the dust mass open, we will find the relationship of the forces between the two surfaces. Our values are,
Distance between the center of lead sphere to dust particle
Gravitational force of the sphere on the dust particle:
Weight of the dust particle
Ratio of F and W:
Therefore the ratio is 
Answer:
Explanation:
66.2mi/h to m/s
×
×
×
- mi will go with mi
- h with h
- min with min
- m/s is left
= 29.58772222
Pls make sure of the way of solving to be sure...
(This is from experience so sorry if it's wrong but) When wind instruments are played, sometimes the notes go flat or sharp depending on the speed the player blows air into the instrument as well as the warmth of the air. When playing a string instrument, the pitch can be changed in many ways. For example, when the player places their fingers on the string depending on which part of the tip of the finger you use, the tone of the sound and sometimes the pitch, changes. Looking at the question in a different way, you can change the pitch and the range of notes you can reach on the instrument (both wind and string) by changing the note you tune your instrument to. Hope this helps!!
