(a) suppose that the displacement of an object is related to the time according to the expression x=bt^2. what are the dimensions of b? (b) a displacement is related to the time as x=a sin (2? ft), where a and f are constants. find the dimensions of a. (hint: a trigonometric function appearing in an equation must be dimensionless.)

a.Dimension of B=

b.Dimension of A=

Step-by-step explanation:

We are given that

a.Suppose that the displacement  of an object is related to time according to the expression

We have to find the dimension of B

Dimension of time=T

Dimension of displacement =L

Substitute the value then we get

Dimension of B=

b.A displacement is related to the time as

x=A sin(2ft)

Where A and f are constants.

We have to find the dimensions of A.

We know that trigonometric function is dimensionless.

Substitute the value then we get

Dimension of A=

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.
