yes, just like human skin. The bigger you grown the more your skin stretches, I a fish is bigger their skin will stretch leading to broad stripes.
Answer:
A: All of the above
Explanation:
The instantaneous speed of an object is simply the current seed of the object at any given time. The SI unit is m/S and it is a vector quantity.
Therefore, according to the given options, they all have SI units that are consistent with distance and time which makes them all an example of instantaneous speed.
Answer:
d. 6/5 M.
Explanation:
let the angular velocity = 
the radius of sphere (r) = 
moment of inertia of solid sphere
= 
rotational K.E of solid sphere= 
= 
we represent the mass of hallow sphere= 
moment of inertia of solid sphere
= 
rotational K.E of hollow sphere= 
= 
NOW,the kinetic energy of solid sphere= 1/2 kinetic energy of hallow sphere
=![1/2 [2/5 M(D/2)^2 ]\omega^2= 1/2 (1/2 (2/3 M_{hs}(D/2)^2 )\omega^2 }](https://tex.z-dn.net/?f=1%2F2%20%5B2%2F5%20M%28D%2F2%29%5E2%20%5D%5Comega%5E2%3D%201%2F2%20%281%2F2%20%282%2F3%20M_%7Bhs%7D%28D%2F2%29%5E2%20%29%5Comega%5E2%20%7D)
2/5M= 1/3
= 3(2/5M)
= 6/5 M
