Which letter correctly identifies the part of the hydrologic cycle that is most directly affected by impervious building materia

Answer:

I do not communicate in Spanish

Explanation:

1 hour = 3,600 seconds
1 km = 1,000 meters

75 km/hour = (75,000/3,600) m/s = 20-5/6 m/s

The mean speed during the deceleration is

                                   (1/2)(20-5/6 + 0) = 10-5/12 m/s.

Traveling at this average speed for 21 seconds,
the bus covers

                        (10-5/12) × (21) = 218.75 meters.

To calculate the rate, first convert units properly. Since 1 kilogram equals 1,000,000 micrograms, 1.6 kilograms is 1,600,000 micrograms. One week has 604,800 seconds. Therefore, dividing 1,600,000 micrograms by 604,800 seconds gives the rate. Simplifying, this results in 2.65 µg/s. I hope this answers your question.

Response:

x = 1.63 m

Details:

mass (m) = 10 kg

μk = 0.3

velocity (v) = 3.1 m/s

Assuming that the weight of the computer is largely applied to the belt instantaneously, we can implement the constant acceleration equation below

x =

where a = μk.g, thus

x = /2μk.g

x = (3.1 x 3.1)/(2 x 0.3 x 9.8)

x = 1.63 m

Response:

The temperature required to achieve this is 286.7°C.

Justification:

Provided information:

Diameter = 20 mm = 0.02 m

Le = characteristic length = 0.02/4 = 5x10⁻³m

Thermal conductivity (K) = 0.3 W/m K

Density times specific heat (ρCp) = 1040 kJ/m³ K = 1.04x10⁶

Time (t) = 3 minutes = 180 seconds

Convection heat transfer coefficient (h) = 10 W/m² K

According to transient heat analysis:

200°C is the minimum temperature requirement; thus, we assume a value of 210°C (10°C higher) to calculate the necessary temperature:
