Step 1. Calculate the water pressure at the bottom of the ocean where the Kursk sank because: Force (F) = Pressure (P) * Area (A). P = ? Step 2. Calculate the area (A) of <span>a 6 foot square</span> metal sheet: A = ? Step 3. Calculate the <span>force on a 6 foot square metal sheet held horizontally at the depth of the Kursk: F = ?
Step 1. The </span>water pressure at the bottom of the ocean is: P = ρ * g * h ρ - the density of the sea water: ρ = 1,027 kg/m³ g - the gravitational acceleration: g = 9.8 m/s² h - the height: h = 350 ft = 106.68 m P = 1,027 * 9.8 * 106.68 = 1,073,691.53 kg/m*s²
Step 2. The area of a <span>6 foot square metal sheet is: A = s</span>² s - the side of the square: s = 6 ft = 1.83 m A = (1.83 m)² = 3.35 m²
Step 3. T<span>he force on a 6 foot square metal sheet held horizontally at the depth of the Kursk is: F = P * A P = </span>1,073,691.53 kg/m*s² A = 3.35 m² F = 1,073,691.53 kg/m*s² * 3.35 m² = 3,596,866.62 N
b) The answer is 3,535,165.59 N.

Step 1. The water pressure at the bottom of the ocean is: P = ρ * g * h ρ - the density of the sea water: ρ = 1,027 kg/m³ g - the gravitational acceleration: g = 9.8 m/s² h - the height: h = 350 ft - 6 ft = 344 ft (Since it is vertically held, the height of the metal sheet must be subtracted from the total depth) h = 344 ft = 104.85 m= 104.85 m P = 1,027 * 9.8 * 104.85 = 1,055,273.31 kg/m*s²
Step 2. The area of a 6 foot square metal sheet is: A = s² s - the side of the square: s = 6 ft = 1.83 m A = (1.83 m)² = 3.35 m²
Step 3. The force on a 6 foot square metal sheet held horizontally at the depth of the Kursk is: F = P * A P = 1,055,273.31 kg/m*s² A = 3.35 m² F = 1,055,273.31 kg/m*s² * 3.35 m² = 3,535,165.59 N
Maps are usually oriented so that North is up. That means the southwest corner is below and to the left of the intersecting lines. Since numbered streets are usually parallel, we're to assume that W 22nd street is parallel to W 20th street. That makes Broadway a transversal of parallel lines, and it makes the angle of interest a corresponding angle to the one whose measure is shown.
In this (assumed) geometry, corresponding angles are congruent, so the angle of interest has measure 105°.
