b. Enlarged brain (compared to body size).
c. No tail.
d. Enlarged Broca's area.
e. Bipedality.

Answers

Answer 1

Bipedality traits are synapomorphies of all hominins (Homo, Australopithecus, Paranthropus, etc.) as compared to chimpanzees, bonobos, and gorillas.

What is the Synapomorphy of the hominins?

When anatomical characters are found to be unique in an ancestor-descendant lineage (or “clade”) they are termed “synapomorphies.” A recent study* found five hominid synapomorphies since the last common ancestor we shared with chimpanzees. Three are found in the base of the skull and two are dental.

What are the 4 traits in hominid evolution?

Some characteristics that have distinguished hominins from other primates, living and extinct, are their erect posture, bipedal locomotion, larger brains, and behavioral characteristics such as specialized tool use and, in some cases, communication through language.

Scientists were surprised by which thing found in Ötzi the Iceman's stomach, and why?

Answers

Answer:

Scientists were surprised to find that Ötzi the Iceman's stomach contained remnants of red deer meat, as it had been previously assumed that his diet consisted primarily of plants. This finding provided new insights into the dietary habits of Copper Age Europeans and challenged previous assumptions about their reliance on agriculture. Additionally, the presence of the red deer meat in Ötzi's stomach suggested that he had eaten a last meal that was high in fat and protein, which may have provided him with the energy needed for his fateful journey through the Alps.

Answer:

Ötzi the Iceman was a well-preserved mummy found in the Italian Alps in 1991. One of the most interesting things about his remains was the discovery of his last meal. Analysis of his stomach contents showed that he had recently eaten a meal of ibex meat, a type of wild goat that lived in the region, and a type of ancient bread made from einkorn wheat. What surprised scientists was the presence of the ibex's stomach contents in Ötzi's stomach. They discovered that Ötzi had eaten the ibex meat raw, with no signs of cooking. This was surprising because it was previously believed that prehistoric humans only ate meat that had been cooked over fire. The discovery of the raw meat in Ötzi's stomach suggested that prehistoric humans may have eaten raw meat more often than previously thought and that cooking food may not have been as prevalent in ancient societies as previously believed.

In order to fill a tank of 1000 liter volume to a pressure of 10 atm at 298K, an 11.5Kg of the gas is required. How many moles of the gas are present in the tank? What is the molecular weight of the gas? Assuming that the gas to be a pure element can you identify it?

Answers

Answer:

The molecular weight will be "28.12 g/mol".

Explanation:

The given values are:

Pressure,

P = 10 atm

  = \(10\times 101325 \ Pa\)

  = \(1013250 \ Pa\)

Temperature,

T = 298 K

Mass,

m = 11.5 Kg

Volume,

V = 1000 r

   = \(1 \ m^3\)

R = 8.3145 J/mol K

Now,

By using the ideal gas law, we get

⇒ \(PV=nRT\)

o,

⇒ \(n=\frac{PV}{RT}\)

By substituting the values, we get

       \(=\frac{1013250\times 1}{8.3145\times 298}\)

       \(=408.94 \ moles\)

As we know,

⇒ \(Moles(n)=\frac{Mass(m)}{Molecular \ weight(MW)}\)

or,

⇒        \(MW=\frac{m}{n}\)

                   \(=\frac{11.5}{408.94}\)

                   \(=0.02812 \ Kg/mol\)

2.24 Carbon dioxide (CO2) gas in a piston-cylinder assembly undergoes three processes in series that begin and end at the same state (a cycle). Process 1-2: Expansion from state 1 where p1 = 10 bar, V1 = 1 m3, to state 2 where V2 = 4 m3. During the process, pressure and pV1.5 volume are related by = constant. Process 2-3: Constant volume heating to state 3 where p3 = 10 bar. Process 3-1: Constant pressure compression to state 1. Sketch the processes on p –V coordinates and evaluate the work for each process, in kJ. What is the net work for the cycle, in kJ?

Answers

Answer:

Explanation:

Given that:

From process 1 → 2

\(P_1 = 10 bar \\ \\ V_1 = 1 m^3 \\ \\ V_2 = 4 m^3\)

\(PV^{1.5} = \ constant\)

\(\gamma = 1.5\)

Process 2 → 3

The volume is constant i.e \(V_2 =V_3 = 4m^3\)

\(P_3 = 10 \ bar\)

Process 3 → 1

P = constant  i.e the compression from state 1

Now, to start with 1 → 2

\(P_1V_1^{1.5} = P_2V_2^{1.5}\)

\(P_2 = P_1 (\dfrac{V_1}{V_2})^{1.5}\)

\(P_2 = 10 \times (\dfrac{1}{4})^{1.5}\)

\(P_2 =1.25\)

The work-done for the process  1 → 2 through adiabatic expansion is:

\(W = \dfrac{1}{1-\gamma}[P_2V_2-P_1V_1]\)

We know that 1 bar = \(10^5 \ N/m^2\)

\(W = \dfrac{1}{1-1.5}[1.25 \times 10^5 \times 4- 10 \times 10^5 \times 1]\)

\(W =1000000 \ J\)

\(W_{1 \to 2} = 1000 kJ\)

For process 2 → 3

Since V is constant

Thus:

W = PΔV = 0

\(W_{2 \to 3} = 0\)

For process 3 → 1

W = PΔV

\(W _{3 \to 1} = P_3(V_1-V_3)\)

\(W _{3 \to 1} = 10 \times 10^5 (1-4)\)

\(W _{3 \to 1} = 10 \times 10^5 (-3)\)

\(W _{3 \to 1} = -3 \times 10^6 \ J\)

\(W _{3 \to 1} = -3000 \ kJ\)

The net work-done now  for the entire system is :

\(W_{net} = W_{1 \to 2} + W_{2 \to 3 } + W_{ 3 \to 1 }\)

\(W_{net} = (1000 + 0 + (-3000)) \ kJ\)

\(W_{net} =-2000 \ kJ\)

The sketch of the processes on p -V coordinates can be found in the image attached below.

2.24 Carbon dioxide (CO2) gas in a piston-cylinder assembly undergoes three processes in series that

A) The work done for each process are :

Process (1 - 2) = 1000 kJ Process (2 - 3) = 0 kJ process (3 - 1) = -3000 kJ

B) The net work for the cycle = -2000 kJ

Given Data :

For process (1 -2)      For process ( 2 - 3 )       process ( 3 - 1 )

P₁ = 10 bar                   P₃ = 10 bar                  constant pressure compression

V₁ = 1 m³                  constant volume heating

V₂ = 4 m³

PV\(^{1.5}\) = constant

A) Determine work done for each process

Calculate work done for process (1 - 2)

W₁ ₋ ₂ = \(\frac{P_{1}V_{1} - P_{2}V_{2} }{n -1 }\) * 100

         = [ ( 10*1 ) - ( 1.25 * 4 ) ] / 1.5 - 1

         = [ 10 - 5 ] / 0.5

         = 10 * 100 = 1000 kJ

Calculate work done for process ( 2-3 )

given that there is constant volume heating

W₂₋₃ = 0 kJ

Calculate work done for process ( 3-1)

W₃₋₁ = P ( Δ V )     given that p = constant

       = 10 * 100 ( -3 )

       = - 3000 kJ

B) The net work for the cycle

W₁ ₋ ₂  +  W₂₋₃  + W₃₋₁

= 1000 kJ  + 0 kJ  +  - 3000 kJ

= - 2000 kJ

Hence we can conclude that the ) The work done for each process are :

Process (1 - 2) = 1000 kJ Process (2 - 3) = 0 kJ process (3 - 1) = -3000 kJ

The acceleration of a particle is defined by the relation a = 9 − 3t2, where a and t are expressed in ft/s2 and seconds, respectively. The particle starts at t = 0 with v = 0 and x = 5 ft. Determine (a) the time when the velocity is again zero, (b) the position and velocity when t = 4 s, (c) the total distance travelled by the particle from t = 0 to t = 4 s.

Answers

(a) To find the time when the velocity is again zero, we set the velocity equal to 0 and solve for t:

0 = v0 + at = 9t - 3t^3

Solving for t, we find that t = ±1.

(b) To find the position and velocity when t = 4 s, we first need to find the velocity equation by integrating the acceleration equation:

v = ∫a = ∫(9 - 3t^2)dt = 9t - t^3 + C

Using the initial condition v(0) = 0, we find C = 0 and

v(t) = 9t - t^3

Next, we integrate v(t) to find the position equation:

x = ∫v = ∫(9t - t^3)dt = 3t^2 - t^4 + C

Using the initial condition x(0) = 5, we find C = 5 and

x(t) = 3t^2 - t^4 + 5

Evaluating x(t) and v(t) at t = 4 s, we have:

x(4) = 3(4^2) - 4^4 + 5 = 51

v(4) = 9(4) - 4^3 = -36

(c) To find the total distance travelled by the particle from t = 0 to t = 4 s, we need to find the distance between the initial and final positions:

d = x(4) - x(0) = 51 - 5 = 46 ft

So the total distance travelled by the particle from t = 0 to t = 4 s is 46 ft.

A "calorie" is a unit of energy, defined as the amount of energy needed to raise the temperature of one gram of water by one degree Celsius. The nutritional labels on food products typically tell you how many calories of digestible energy are in one serving of food, where "digestible" means that the energy stored in the chemical bonds of the molecules comprising the food can be extracted by your body. (Water for example has energy, but that energy is not chemically accessible via digestion.) To simplify understanding for typical consumers, the "calories" reported on nutritional labels actually represent kilocalories: a 170 calorie can of beer actually contains 170,000 calories of digestible energy i) If a student foolishly decides to binge drink 21 beers on their 21t birthday, how many gallons of water could they have heated from room temperature (24 °C) to boiling (100 C) using an equivalent amount of digestible energy in the beer? Recall that one gallon of water is roughly 8 pounds ii) What is this energy equivalent to in BTU? A "BTU" or British Thermal Unit is also a unit of energy, defined as the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit iii) If you had purchased an equivalent amount of electrical energy in kW-hr from the utility company, how much would you have to pay? Is this cheaper than buying beer? A kW-hr ypically costs 10 cents

Answer & Explanation:

i) If a student foolishly decides to binge drink 21 beers on their 21st birthday, they would consume a total of 21 x 170 = <<21*170=3570>>3570 calories of digestible energy. Since one calorie is equivalent to raising the temperature of one gram of water by one degree Celsius, and one gallon of water is equivalent to 3,785 grams, the student would have consumed enough energy to raise the temperature of 3,785 grams x 3570 calories = 13,678,950 calories of water from 24 °C to 100 °C. This means that the student could have heated 13,678,950 / 100 = <<136789500/100=136789.5>>136789.5 grams of water from room temperature to boiling, which is equivalent to 136789.5 / 3,785 = <<136789.5/3785=36.19>>36.19 gallons of water.

ii) The energy equivalent of the beer consumed by the student is 3570 calories x 4.184 joules/calorie = 14,889.48 joules. Since one BTU is equivalent to 1,055 joules, this energy is equivalent to 14,889.48 joules / 1,055 joules/BTU = <<14889.48/1055=14.15>>14.15 BTU.

iii) If the student had purchased an equivalent amount of electrical energy from the utility company, they would have to pay 14.15 kW-hr x $0.10/kW-hr = $<<14.15*0.1=1.42>>1.42. This is cheaper than buying beer, as a can of beer typically costs more than $1.42.

The following statement of the document is false.

What do you mean by document?

A document is a written, drawn, presented, or documented statement of ideas that frequently includes both non-fictional and fictitious content. The term comes from the Latin Documentum, which means "teaching" or "lesson": the verb doce means "to teach." Historically, the term was used to refer to written proof that may be used as evidence of a truth or reality. "Document" in the computer age usually refers to a mostly textual computer file, including its structure and format, such as fonts, colours, and graphics. Given the existence of electronic documents, the term "document" is no longer defined by its transmission medium, such as paper.
