"One of the dangers of tornados and hurricanes is the rapid drop in air pressure that is associated with such storms. Assume tha
galben [10]

Answer:

Net outward force exerted on the window = 45.931_KN

Explanation:

In the hurricane, the pressure outside the window = 0.910_atm

Pressure inside the sealed house = 1.02_atm

Size of windows sides = 2.03_m

But pressure = force/area

Therefore, force = pressure × area

Where 1.00 atm = 1.01 × 10^5 Pa

0.910_atm = 1.01 × 10^5 Pa × 0.910 = 0.9220575_Pa

Also 1.02_atm = 1.03 × 10^5 Pa

Area of widow = 2.03^2 = 4.12_m^2

Force on the outside of the window = 0.9220575_Pa × 4.12_m^2 = 379.971_KN

Force on the inside of the window = 1.03 × 10^5 Pa × 4.12_m^2 = 425.9 KN

Net outward force exerted on the window = 425.9_KN - 379.971_KN = 45.931_KN

Net outward force exerted on the window = 45.931_KN

Riya rides his bike 63 miles in 270 minutes. What is his average speed in miles per hour? Be sure to include the equation for sp
bekas [8.4K]

Answer:

14mph

Explanation:

270 minutes = 4 hr and 1/2hr

63 miles = 63/4.5 = 14 miles per hour

Making the speed 14mph

Equation = h = 4.5     

(4h x 4h ) + (1 x 311/100) = 60

= 4h x 4h +( 1 x 311/100) =60

= 16h^2 + (1 x 311/100) =60

= 256h + (1 x 311/100) =60

= 256h + 14 = 60

= 270h  =  60

= h = 4.5

What is the total mass (in grams) of 1.000 l of an aqueous 1.500 m nacl solution with a density of 1.058 g/ml? (do not include t
lawyer [7]

The density is an unique property of a compound in solid or liquid phase. The density is the mass of the compound in its unit volume. Now due to the addition of an particular amount of solid like in this case salt  (NaCl) the density of the water will change and the density given will be the density of the salted water.

The volume of the salted water is 1L or 1000mL. The density of the salted water is 1.058g/mL. Thus the 1 mL of the solution have the mass 1.058 g. Thus 1000 mL of the solution will have mass 1058.
