Answer:

P2= 0.696atm

Explanation:

Applying Boyle's law

P1V1= P2V2

1.14×16.9= P2× 27.7

Simplify

P2= (1.14×16.9)/27.7

P2= 0.696atm

C. the square root of 2gh

Explanation:

The square root of 2gh is equivalent to Torricelli's law in the equation.

  given expression:

         \frac{1}{2} m v² = mgh

 to find v, we make it the subject of the expression:

    *multiply both sides of the equation by 2:

             

                     2 x( \frac{1}{2} m v² )= 2 (mgh)

                                      mv²  = 2mgh

    *cancel the mass, m appearing on both sides:

                                    v²  = 2gh

  * find the square root of both side

                                     v = √2gh
