lord [1]

The problem is,

→ (2√3)/√12

Let's simplify the problem,

→ (2√3)/√12

→ (2√3)/(√4 × √3)

→ (2√3)/(2 × √3)

→ (2√3)/(2√3) = 1

Hence, the answer is 1.

Use the formula s = rwt to find the value of the
Vinil7 [7]

Answer:

π/36 sec-1

Step-by-step explanation:

From the question we are given the formula below

s = rwt ..........eqn(1)

Where s= π/3m, r=3 m, t= 4 sec

We were not given value of " w" which implies we are required to find out values of" w"

We can make " w " the subject of the formula from eqn(1)

s = rwt

w= s/(rt)........eqn(2)

Then substitute for the values in eqn(2)

w= (π/3m ) / ( 3m × 4 sec)

= π/36 sec-1

Hence, the value of the

missing variable is π/36 sec-1
