1) The thickness of the Styrofoam is 3.00 cm = 1.181 in.

2) the mass of Styrofoam is 1.9 slugs.

3)  the number of gallons of liquid that could be stored in the cooler is 61 gallons.

1) To find the volume of Styrofoam used, we first need to convert the dimensions from centimeters to inches:

50.0 cm = 19.685 in

35.0 cm = 13.780 in

30.0 cm = 11.811 in

The thickness of the Styrofoam is 3.00 cm = 1.181 in.

The volume of the Styrofoam used is:

V = (19.685 in) x (13.780 in) x (1.181 in) = 3223.6 in3

Rounding to the appropriate number of significant figures, the volume of Styrofoam used is 3200 in3.

2)To find the mass of Styrofoam in slugs, we first need to convert the density from kg/m3 to slugs/in3:

1 kg/m3 = 0.000578 slugs/in3

The volume of the Styrofoam used is 3223.6 in3 (from part 1).

The mass of the Styrofoam is:

m = (3223.6 in3) x (1.00 kg/m3) x (0.000578 slugs/in3) = 1.86 slugs

Rounding to the appropriate number of significant figures, the mass of Styrofoam is 1.9 slugs.

3) To find the number of gallons of liquid that could be stored in the cooler, we need to first find the volume of the cooler in cubic inches.

V = (19.685 in) x (13.780 in) x (30.0 cm + 2 x 3.0 cm) = 14157 in3

Next, we need to convert the volume from cubic inches to gallons:

1 gallon = 231 in3

The volume of the cooler in gallons is:

V = (14157 in3) / (231 in3/gallon) = 61.2 gallons

Rounding to the appropriate number of significant figures, the number of gallons of liquid that could be stored in the cooler is 61 gallons.

The effects of soil erosion in tabular form as it affects plants, humans, and landforms is attached accordingly.

Erosion is the activity of surface processes that transfer soil, rock, or dissolved material from one spot on the Earth's crust to another where it is deposited. Weathering, on the other hand, does not entail mobility.

Soil erosion reduces soil fertility, which can reduce crop output. It also pushes soil-laden water downstream, which can result in thick layers of silt that clog streams and rivers and eventually contribute to floods.

Explanation:

Given: Family Budget comprises of 23% housing, 21% food, 10% savings, 16% transportation, 12% medical, 13% clothing and 5% emergency fund.

To find: categories that make up more than half of the Hernandez family budget

Solution:

clothing + medical + emergency fund = \(13+12+5=30 \%\)

clothing + housing + savings = \(13+23+10=46\%\)

housing + savings + food = \(23+10+21=54\%\)

housing + food + transportation = \(23+21+16=60\%\)

food + transportation + emergency fund = \(21+16+5=42\%\)

So, 3 categories that make up more than half of the Hernandez family budget are housing, savings, and food, housing, food, and transportation

If the wind has to suddenly go through a small area, the wind’s speed increases.

Slide 3:

Objects move from areas of high pressure to areas of low pressure.

If you blow directly onto something, it moves farther away because your wind is high-pressure.

If you blow along the surface of an object, the object moves in the same direction as the wind.

Moving fluids create a stream of low pressure.

The faster the fluids flow, the lower the pressure becomes.

Wings are curved on the top and flat on the bottom.

The distance the air has to travel over the top of the wing is a longer distance than the distance it has to travel underneath the wing.

It takes the air the same amount of time to get around the wing whether it goes over or under it.

Therefore, air going over the wing is moving faster than air going under the wing.

The figure is shown in the picture.

Engine types: •In-line engines feature cylinders that are lined up in a row (ex. In-line 4)

•When viewed from the front of the engine, cylinder banks of V-Type engines are positioned at an angle to one another. This creates a "V" shape.

The cylinders of horizontal/flat engines are situated on each side of the central crankshaft. Example: Boxer engine

Answer:

A continuously variable transmission (CVT) is an automatic transmission that can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant RPM while the vehicle moves at varying speeds.that means the ans is A.

A continuously variable transmission requires a transmission fluid specially formulated for CVT needs. The correct option is C.

Because a CVT operates differently than a traditional step-gear transmission, it requires a unique type of transmission fluid that is formulated to meet its specific performance requirements.

CVT fluid helps to maintain the proper frictional properties of the transmission's belts and pulleys, as well as providing cooling and lubrication for the transmission components.

While CVT fluid should be changed at the manufacturer's recommended intervals, it does not have to be changed as frequently as the fluid in a traditional automatic transmission.

Thus, the correct option is C.

The Answers for the given question are as follow:

a. The model speed is approximately 31.62 rev/min.

b. The scale ratio is approximately 0.0417.

c. The estimated volume flow rate through the model is approximately 943.44 m^3/s.

d. The bearing thrust of the model is approximately 9.72 kN.

To calculate the required values for the water turbine model, we can utilize the concept of dynamic similarity.

a. To find the model speed, we can use the principle of geometric similarity, which states that the ratio of speeds is equal to the ratio of the square roots of the head. Thus:

  Model speed = (√(Model head))/(√(Full-size head)) * Full-size speed

              = (√4.9/√16.5) * 93.7 rev/min

              = 31.62 rev/min

b. The scale ratio can be determined using the equation:

  Scale ratio = (√(Model power))/(√(Full-size power))

             = (√37.5kW)/(√27MW)

             ≈ 0.0417

c. To estimate the volume flow rate through the model, we can use the power equation:

  Model power = (Model efficiency) * (Volume flow rate) * (Model head) * (Gravity)

  37.5kW = 0.88 * (Volume flow rate) * 4.9m * (9.81m/s^2)

  Solving for the volume flow rate:

  Volume flow rate = 37.5kW / (0.88 * 4.9m * 9.81m/s^2)

                   ≈ 943.44 m^3/s

d. To calculate the bearing thrust of the model, we can use the principle of force similarity:

  Bearing thrust model = (Model power / Full-size power) * Full-size bearing thrust

                      = (37.5kW / 27MW) * 7.0GN

                      ≈ 9.72kN

The flux of nitrogen through the foil is 1.225 x \(10^{-7\) atomic/(\(cm^2\)*s).

The electric flux is defined as the total number of electric field lines passing through a given area in a given unit of time.

To solve this problem, we can use Fick's first law of diffusion, which relates the flux of atoms to the concentration gradient:

J = -D x (dC/dx)

Where J is the flux of atoms (in atoms/(cm^2*s)), D is the diffusion coefficient, C is the concentration of nitrogen (in atomic percent), and x is the distance across the foil.

We can assume that the diffusion coefficient for nitrogen in FCC iron at 1200 °C is approximately 3.5 x \(10^{-7\) \(cm^2\)/s. We can also assume that the foil is flat and that the concentration gradient is uniform across its thickness.

Using these assumptions and the given concentrations, we can calculate the concentration gradient:

dC/dx = (0.04 - 0.005) / (1 mm) = 0.035 / 0.1 cm = 0.35 atomic percent/cm

Now we can plug in the values into Fick's first law of diffusion:

J = - (3.5 x 10^-7 cm^2/s) * (0.35 atomic percent/cm)

J = - 1.225 x \(10^{-7\) atomic/(\(cm^2\)*s).

Since the flux is negative, we can interpret this as meaning that nitrogen is diffusing from the surface with the higher concentration (0.04 atomic percent) to the surface with the lower concentration (0.005 atomic percent), as we would expect.

Therefore, the flux of nitrogen through the foil is 1.225 x \(10^{-7\) atomic/(\(cm^2\)*s).
