The position of a particle moving under uniform acceleration is some function of time and the acceleration. suppose we write this position as x = kamtn, where k is a dimensionless constant. show by dimensional analysis that this expression is satisfied if m = 1 and n = 2. (submit a file with a maximum size of 1 mb.)

Explanation:

k is constant , it is dimension is zero. Using dimensional unit , we cal write the relation as follows

L =

=

Equating power of like items

m=1

-2m+n = 0

n = 2

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
