Question

pls answer this for me intelligennts

Answer 1

1) = 3

2) = 1

3) = 2

4) = 4

sol^n

F = AcosBx+CsinDt

the trigonometric functions are

dimensionless for this we need

dimension of B = L^-1 and D= T^-1

(-1 are there powers understand)

A and C are constants due to this it is dimensionless

A/C has dimensions = M^0L^0T^0

B/D has dimensions = M^0L^1T^-1

(are your doubt is clear)

5)= sorry, i fell to solve this question
