2.1 Given that the speed of light, v, in a fluid depends on an elastic modulus, T. with

dimensions ML-'T-2 and the fluid density, p, in the form v = (T)°(p). If this is to be a

dimensionally homogeneous equation, determine the values of a and b and write the

simplest form of an equation for the speed of light, W.

Explanation:

Using dimensional formula on both sides ,

LT⁻¹ =

=

equating the power of equal terms

- 2 a = -1

a = 0.5

-0.5 -3b = 1

3b = -1.5

b = -0.5

a + b = 0

Hence

a = 0.5

b = -0.5

1 a

2 b

3 b

explanation:

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
