Question

What is the “center of gravity of a band”?

Answer 1

Hey here your answer  the centre of gravity of Band is the total formation of sound produced by an object  example the centre and the middle part of the band or a drum produces a large sound  Hope that help you....

Answer 2

As we Know the formula :
g= GM/R²----------------(1)
where g is acceleration due to gravity
M is mass of the earth
R is radius of earth
G is universal gravitational constant.

If mass is twice =2M
RADIUS is half= R/2
let g1 be the new gravity .

Substituting in formula (1) we get.
g1= Gx2M/(R/2)²

g1=8 (GM/R²)
g1= 8xg

So the new gravity would be 8 times of original value that is 9.8 m/s².

Hence g1=78.4m/s²
