**Answer:**

165.11 K Pa

**Explanation:**

Applying Bernoulli theorem ,the problem which deals with the conservation of energy of a flowing fluid , we have

P + 1/2ρ v² + ρgh = constant

P represents pressure , ρ represents density of liquid flowing v is velocity, h is the height from the ground.

P₁ + 1/2ρ v₁² + ρgh₁ =P₂ + 1/2ρ v₂² + ρgh₂

Substituting the values we get

46.4 x 10³ + .5 x 1000 x (4.37)²+ρg( h₁ - h₂) = P₂ + .5 X 1000x(4.37/4)²

46400+ 9548.45 +1000x 9.8 x 11.2 = P₂ +596.78

P₂ = 165.11 K Pa

**Answer:**

Send a pic of it so i can mark it.

**Explanation:**

The PWC must be slowed to "slow, no wake" speed when the operator is **within 50 feet of the swimmer.
**

"Slow, no wake" speed means the boat is at its slowest needed to keep steerage, reducing or getting rid of waves that comes out as white water trailing the boat.

Ah yes the answer to that is
