Answer:
-0.10472
Explanation:
Remember that any <u><em>clockwise</em></u> rotation is considered negative, and any <u><em>counterclockwise</em></u> rotation is considered positive.
The formula for period is:
Solve for and you get:
The period is 60 seconds so make that division and you're left with -0.10472 or -0.10 if significant figures apply (negative because the rotation is clockwise).
-- The volume of water is (1.5 m² x 7 m) = 10.5 m³
10.5 m³ = 10,500 liters
Water mass = (10,500 liters) x (1 kg/liter) = 10,500 kg.
-- "Force of gravity on the water"
= Weight of the water = (10,500 kg) x (9.8 m/s²) = 102,900 newtons
-- Pressure on the bottom of the tank =
(102,900 newtons) / (1.5 m²)
= 68,600 nt/m² = 68,600 pascal .
