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

Explanation:

The time that customers wait to be served at the deli for a grocery store follows the uniform distribution between 0 and 7 minutes. What is the probability that a randomly selected customer will wait more than 4 minutes at the deli?.

Answers

The probability that a randomly selected customer will wait more than 4 minutes at the deli is given below

The probability that a randomly selected customer will wait more than 4 minutes = [tex]0.4286[/tex]

The waiting time for the customers is uniformly distributed between 0 - 7 minutes

Consider a random variabe X that represents the waiting time of customers and uniformly distributed between 0-7 minutes

Therefore, the density function of X is determined as

[tex]f(x) = \frac{1}{b-a}\\\\f(x) = \frac{1}{7-0}\\\\f(x) = \frac{1}{7}[/tex]

The probability that the customer will wait more than 4minutes,

[tex]P(X>4) = \int\limits^7_4 f{x} \,dx\\\\= \int\limits^7_4 \, \frac{1}{7}dx\\\\= \frac{1}{7} * [x]^7_4\\\\= \frac{7-4}{7} \\\\= 0.4286[/tex]

A particle moves along the curve y = 4x2 + 1 in such a way that the x value is increasing at the rate of 2 units per second. At what rate is y changing when x = 1?.

Answers

By differentiating both sides of y = 4x² + 1 with respect to time t, we have

dy/dt = 8x dx/dt

If the x value changes at a rate of +2 units/second (that is, dx/dt = 2) at the moment x = 1, then the y value changes at a rate of

dy/dt = 8 • 1 • 2 units/s = 16 units/s

Even at moderate temperatures, attractions between molecules seem to have little effect on the elasticity of gas-gas collisions because.

Answers

Attractions have little effect on the elasticity of gas-gas collisions because they are brief and fast. These particle collisions exhibit insufficient time to significantly affect the entire system.

The Kinetic Molecular Theory (KMT) is a model used in order to describe the behavior of gases by understanding the behavior of an ideal gas.

According to this theory, collisions between particles of gases are elastic, and therefore the kinetic energy is conserved when they collide.

An elastic collision can be defined as a type of collision between two particles in which the total kinetic energy remains the same.

Place the events that form hurricane-force winds in order.

Answers

Answer: The events that form hurricane-force winds are as follows

1. Tropical disturbance

2. Tropical depression

3. Tropical storm

4. Hurricane.

Explanation:

All of the above-mentioned events happen in chronological order for the hurricane-force winds to occur.

1. Tropical disturbance occurs from the tropics and the subtropics. These are generally 100-300 miles in diameter. It is a tropical weather system of organized conventions. This is the first stage that consists of a loosely organized low-pressure area.

2. Tropical depression is a more organized deep convention and has a closed circulation of sustained winds of less than 39 mph.

3. Tropical storm is the third stage that has sustained winds between 39 - 73 mph.

4. The hurricane is created when the sustained winds finally reach or cross the speed of 74 mph.

This is how hurricane-force winds are created.
