In casting experiments performed using a certain alloy.

Answers

Answer 1
Answer:
A) Cm = 2.232 s/mm²
B) Time taken to solidify = 74.3 seconds
Explanation:
(A) Since a side is 50mm and all sides of a cube are equal, thus, Volume of the cube is;V = 50 x 50 x 50 = 125,000 mm³
There are 6 faces of the cube, thus Surface Area A = 6 x (50 x 50) = 15,000 mm²
So, Volume/Area = (V/A) = 125,000/15,000 = 8.333 mm
Cm is given by the formula; Cm =[Tts] /(V/A)² where Tts is time taken to solidify and it's 155 seconds in the question. Thus;
Cm = 155/(8.333)²= 2.232 s/mm²
(B) For;Cylindrical casting with D = 30 mm and L = 50 mm.;
Volume of cylinder is;
V = (πD²L) /4
So,V = (π x 30² x 50)/4 = 35,343mm³
Surface area of cylinder is;
A = (2πD²)/4 + (πDL)
Thus, A = ((π x 30²)/2) + (π x 30 x 50) = 6126 mm²
Volume/Area is;
V/A = 35,343/6126 = 5.77 mm
Same alloy and mold type was hsed as in a above, thus, Cm is still 2.232 s/mm²
Since Cm =[Tts] /(V/A)²
Making Tts the subject, we have;
Tts =Cm x (V/A)²
Tts = 2.232 x (5.77)² = 74.3 seconds

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics?.

Answers

Answer:

The first law describes how thermal energy is conserved but not the direction it moves.

 

Thermodynamics is demonstrated as the branch of physics that deals with the associations or relationships between heat and other energy forms like mechanical, chemical, and electrical).

As per the question, the first law discusses that heat is a kind or form of energy and thus, processes associated with thermodynamics are subject to energy conservation principle. Therefore, heat energy can neither be destroyed nor created but rather transferred to one place to another and converted to and from other energy forms.

Thus, the first law of thermodynamics is distinct from the second law as 'the former describes how thermal energy can be conserved to and from other forms of energy and not the direction in which it moves' while the second law focuses on entropy.

Answers

Considering the situation described above, the measures that would be most appropriate for the nurse to suggest is that the mother should not offer the child snacks so that the child is hungry and subsequently offer the child the main meal.

What is Main Meal?

The main meal is the conventional food prepared to serve breakfast, lunch, or dinner.

In this situation, given that the child only eats animal crackers and peanut butter and jelly sandwich, which is a form of snacks or junk, the only way to make the child eat good food is to starve him from snacks and only serve his main meal.

A food worker takes three hours to reheat a pot of soup for a buffet to 165°f (74°c).

Answers

An action the food worker must take next is to throw the soup out.

Food preservation is an art that typically involves the process of preventing food spoilage by mitigating or reducing the activities (growth) of microbial organisms and other external factors while maintaining the nutritional value, flavor and texture of a food.

Some of the common factors that result in food spoilage include the following:

TemperatureOxidationMoisture contentPathogens (microorganisms) such as yeast, molds, bacteria, etc.

A soup is an example of a time/temperature control for safety (TCS) foods because they are more susceptible to the growth of pathogens (microorganisms) such as yeast, molds, bacteria, etc.

For TCS foods, it is important that they are cooled from 135 Fahrenheit (°F) to 70 Fahrenheit (°F) within two (2) hours, else, it must be thrown out. Since this food worker took three (3) hours to reheat the pot of soup to 165°F (74°C), he or she must throw the soup out because it has exceeded the minimum time required for TCS foods.

If a recessive allele helps an organism reproduce but a dominant allele hinders reproduction, which will become more prominent over time?.

Answers

It is expected the recessive allele becomes more prominent over time.

In general, nature favors traits that help organisms survive and reproduce. This occurs through a process known as natural selection that helps the population to evolve to have favorable traits.

This evolution occurs externally as organisms change their physical traits or phenotype, but also at a genetic level.

This implies that even if a trait is genetically dominant if the trait does not favor survival and reproduction, this trait will slowly disappear or reduce over generations.

Based on this, the recessive allele will become more prominent because this trait favors reproduction, while the dominant allele will become less prominent.

What are the equations of the asymptotes of the hyperbola? (y+4)236−(x−6)249=1 enter your answer in point-slope form by filling in the boxes. Enter the slope as a simplified fraction.

Answers

The point slope form of the asymptote of the hyperbola is; y - 4 = ±(6/7)(x - 6)

We are given the equation of the hyperbola as;

[(y + 4)²/36] - [(x - 6)²/49] = 1

We can rewrite this equation as;

[(y + 1)²/6²] - [(x - 6)²/7²] = 1

The general equation form of hyperbola is;

[(y - k)²/a²] - [(x - h)²/b²] = 1

Comparing this general form to our given equation we can see that;

k = -4

h = 6

a = 6

b = 7

Now the equation of the asymptote of a hyperbola follows the general formula;

y = ±[a(x - h)/b] + k

Plugging in the relevant values gives us;

y = ±(6/7)(x - 6) - 4

>> y - 4 = ±(6/7)(x - 6)

A group of campers walked at a speed of 4. 5 mph from their campsite to a rest area. Their return trip to the campsite took 15 minutes longer because their speed was only 4 mph. What is the distance between the campsite and the rest area?.

Answers

The distance between the campsite and the rest area is 9 miles.

The given parameters:

Initial speed of the campers, u = 4.5 mphFinal speed of the campers, v = 4 mph

Let the time of motion from the campsite to rest area = t (hours)

Time for return trip = t hours +  15 mins

                               = (t + 0.25) hours

Let the distance between the campsite and rest area = d

d = 4.5t

d = 4(t + 0.25)

4.5t = 4(t + 0.25)

4.5t = 4t + 1

4.5t - 4t = 1

0.5t = 1

t = 2 hours

The distance between the campsite and the rest area is calculated as follows;

d = 4.5t

d = 4.5 x 2

d = 9 miles

Thus, the distance between the campsite and the rest area is 9 miles.

When the spring is stretched to 11.0 cm - 8.0 cm = 3.0 cm = 0.030 m away from equilibrium, it stores

1/2 (150 N/m) (0.030 m)² = 0.0675 J

of potential energy, while stretching it to 14.0 cm - 8.0 cm = 6.0 cm = 0.060 m from equilibrium stores

1/2 (150 N/m) (0.060 m)² = 0.27 J

Then the change in potential energy is 0.27 J - 0.0675 J = 0.2025 J ≈ 0.21 J
