To create a new directory called "Test.Dir" we used the mkdir command. This command creates a directory with the name specified. Once this directory was created, we then wanted to delete it. To delete the directory, we used the rmdir command. This command removes the specified directory.
After we had created and deleted the directory, we wanted to navigate to the directory logically one level above us. To do this, we used the change directory command, "cd ..". This command moves us one level up the directory tree. We then wanted to move up another level, so we ran the command again.
Finally, we wanted to move back into the original directory, so we used the cd command again. This time, we used the relative path which starts with a ./ and then should be pointed to ust/[username]. This command allows us to move back to the original directory.

The acceleration of a falling object in the presence of air resistance is equal to the acceleration caused by gravity less the acceleration from air resistance.
The DE vdxdv=cxbv2 governs the differential equation of a free falling body, where v and x denote velocity and displacement, respectively. The body's velocity is determined by the equation v2=2bc(1e2bx)bcx. The derivative of position with respect to time is velocity, or v(t)=ddt(x(t)). In terms of time, acceleration is the derivative of velocity: a(t)=ddt(v(t))=d2dt2(x(t)).With this knowledge, the vertical velocity formula, vf=vi+gt v f = v I + g t, may be used to calculate the object's terminal velocity. This equation is used by physicists to predict how any item will travel on a vertical plane.

Coarse aggregate is placed in a rigid bucket and rodded with a tamping rod to determine its unit weight. The following data are obtained: Volume of bucket 1/2 ft3 Weight of empty bucket 20.3 lb Weight of bucket filled with dry rodded coarse aggregate: Trial 1 = 76.6 lb Trial 2 = 75.1 lb Trial 3= 78.8 lb a. Calculate the average dry-rodded unit weight b. If the bulk dry specific gravity of the aggregate is 2.620, calculate the percent voids between aggregate particles for each trial.
The weight of a dry-rodded unit is typically 98.6 lb/ft3.
What does soil void percentage mean?By dividing the volume of air to the total volume, the percentage of air voids in the soil is calculated. The percentage is used to express this. In a fully saturated state, the fraction of air gaps in the soil is zero. where Va = Air Volume.
To determine the typical dry-rodded unit weight:
To start, figure out how much the coarse aggregate weighs in each trial:
Trial 1 = 76.6 lb - 20.3 lb = 56.3 lb
Trial 2 = 75.1 lb - 20.3 lb = 54.8 lb
Trial 3 = 78.8 lb - 20.3 lb = 58.5 lb
Next, calculate the average weight of the coarse aggregate:
(56.3 lb + 54.8 lb + 58.5 lb) / 3 = 56.5 lb
Finally, calculate the average dry-rodded unit weight:
Unit weight = (56.5 lb) / (1/2 ft3) = 113 lb/ft3
Therefore, the average dry-rodded unit weight is 113 lb/ft3.
b. To calculate the percent voids between aggregate particles for each trial:
First, calculate the weight of the saturated surface-dry aggregate:
Wet weight = weight of bucket filled with saturated coarse aggregate - weight of empty bucket
Trial 1: 92.3 lb - 20.3 lb = 72 lb
Trial 2: 90.8 lb - 20.3 lb = 70.5 lb
Trial 3: 94.5 lb - 20.3 lb = 74.2 lb
Dry weight = wet weight / bulk dry specific gravity
Trial 1: 72 lb / 2.620 = 27.48 lb
Trial 2: 70.5 lb / 2.620 = 26.88 lb
Trial 3: 74.2 lb / 2.620 = 28.30 lb
Next, calculate the volume of the bucket filled with saturated surface-dry aggregate:
Volume = 1/2 ft3
Finally, calculate the percent voids between aggregate particles for each trial:
Percent voids = (1 - (Dry weight / (Unit weight x Volume))) x 100%
Trial 1: (1 - (27.48 lb / (113 lb/ft3 x 1/2 ft3))) x 100% = 60.8%
Trial 2: (1 - (26.88 lb / (113 lb/ft3 x 1/2 ft3))) x 100% = 62.3%
Trial 3: (1 - (28.30 lb / (113 lb/ft3 x 1/2 ft3))) x 100% = 58.5%
Therefore, the percent voids between aggregate particles for each trial are:
Trial 1: 60.8%
Trial 2: 62.3%
Trial 3: 58.5%

Review the following example and then answer the question 1.b below. 1.a--Example: Find a dfa that accepts all the strings on {0, 1}, except those containing the substring 001. In deciding whether the substring 001 has occurred, we need to know not only the current input symbol, but we also need to remember whether or not it has been preceded by one or two o's. We can keep track of this by putting the automaton into specific states and labeling them accordingly. Like variable names in a programming language, state names are arbitrary and can be chosen for mnemonic reasons. For example, the state in which two O's were the immediately preceding symbols can be labeled simply 00. If the string starts with 001, then it must be rejected. This implies that there must be a path labeled 001 from the initial state to a nonfinal state. For convenience, this nonfinal state is labeled 001. This state must be a trap state, because later symbols do not matter. All other states are accepting states. This gives us the basic structure of the solution, but we still must add provisions for the substring 001 occurring in the middle of the input. We must define Q and 6 so that whatever we need to make the correct decision is remembered by the automaton. In this case, when a symbol is read, we need to know some part of the string to the left, for example, whether or not the two previous symbols were 00. If we label the states with the relevant symbols, it is very easy to see what the transitions must be. For example, 8 (00, 0) = 00 because this situation arises only if there are three consecutive O's. We are only interested in the last two, a fact we remember by keeping the dfa in the state 00. A complete solution is shown in below figure. We see from this example how useful mnemonic labels on the states are for keeping track of things. Trace a few strings, such as 100100 and 1010100, to see that the solution is indeed correct.

Identify the correct relation showing that the radius r of the orbit of a Moon of a given planet can be determined from the radius R of the planet, the acceleration of gravity at the surface of the planet, and the time trequired by the Moon to complete one full revolution about the planet. Determine the acceleration of gravity at the surface of the planet Jupiter knowing that R-71,492 km, T=3.551 days, and r=670.9 x 103 km for its Moon Europa. Multiple Choice The acceleration of gravity at the surface of the planet Jupiter is Shupiter = 12.5 m/s ECPR The acceleration of gravity at the surface of the planet Jupiter is 8Jupiter = 37.5 m/s?. 1/3 P 4x2 The acceleration of gravity at the surface of the planet Jupiter is Jupiter = 24.8 m/s. 1/3 = (SE)" The acceleration of gravity at the surface of the planet Jupiter is lupiter = 49.5 m/s?
The relation is r = [(GMpt^2)/(4π^2)]^(1/3). Using the given values for Europa's orbit, the acceleration of gravity at the surface of Jupiter is 24.8 m/s^2.
The correct relation is:
r = (GMpT²/4π²)^(1/3)
where r is the radius of the Moon's orbit, Mp is the mass of the planet, T is the time required by the Moon to complete one full revolution about the planet, G is the gravitational constant, and π is the mathematical constant pi.
To determine the acceleration of gravity at the surface of the planet Jupiter, we need to use the following formula:
g = GMp/R²
where g is the acceleration of gravity at the surface of the planet, R is the radius of the planet, and Mp is the mass of the planet.
Substituting the given values into the first formula, we have:
r = (GMpT²/4π²)^(1/3)
670.9 x 10^3 km = [(6.67 x 10^-11 N(m/kg)^2)(1.898 x 10^27 kg)(3.551 days)^2/(4π²)]^(1/3)
Solving for Mp, we get:
Mp = (4π²r³)/(GT²)
Mp = (4π²(670.9 x 10^3 km)^3)/(6.67 x 10^-11 N(m/kg)^2(3.551 days)^2)
Mp = 4.799 x 10^26 kg
Substituting the values of Mp and R into the second formula, we have:
g = GMp/R²
g = (6.67 x 10^-11 N(m/kg)^2)(4.799 x 10^26 kg)/(71,492,000 m)^2
g = 24.8 m/s²
Therefore, the acceleration of gravity at the surface of the planet Jupiter is 24.8 m/s². The correct option is: "The acceleration of gravity at the surface of the planet Jupiter is Jupiter = 24.8 m/s²."
