The torque required to maintain motion of the rotating conical body in the oil film is 0.149 N·m.

The torque required to maintain motion of a rotating conical body in an oil film can be found using the equation T = (2πμωR^3h)/ln(R/h), where T is the torque, μ is the viscosity of the oil, ω is the angular velocity of the cone, R is the radius of the base of the cone, and h is the thickness of the oil film.

First, we need to convert the given values into the appropriate units. The diameter of the base of the cone is 18cm, so the radius is 9cm or 0.09m. The thickness of the oil film is 0.8mm, or 0.0008m. The viscosity of the oil is 4·10^-3 N·S/m^2, and the angular velocity of the cone is 37 rad/s.

Now we can plug these values into the equation:

T = (2π)(4·10^-3 N·S/m^2)(37 rad/s)(0.09m)^3/(0.0008m)

T = 0.149 N·m

Therefore, the torque required to maintain motion of the rotating conical body in the oil film is 0.149 N·m.

To select the indicated motor, we need to find a motor that can provide a torque of at least 0.149 N·m. This will ensure that the motor can maintain the constant motion of the conical body in the oil film.

Step-by-step explanation:

The ANOVA will depend on the total sample size.

a. False. The psychologist's reasoning is incorrect, as the critical value for evaluating the ratio of between-group mean squares to within-group mean squares for the ANOVA does not depend solely on the total sample size, but also on the number of groups being compared and the level of significance. Furthermore, a Bonferroni adjusted post-hoc test does not require the p-value for each pairwise comparison to be no more than .0083 to be considered as statistically significant.

b. True. The critical value for evaluating the ratio of between-group mean squares to within-group mean squares for the ANOVA will depend on the total sample size, as well as on the number of groups being compared and the level of significance. Therefore, if the observed means across the three conditions differ entirely due to sampling errors, the critical value for evaluating the ratio of between-group mean squares to within-group mean squares for the ANOVA will depend on the total sample size.

The area of the composite figure given is 39 cm²

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object. The space enclosed by the boundary of a plane figure is called its area. The area of a figure is the number of unit squares that cover the surface of a closed figure.

Given is a figure with dimensions, 3 cm 4 cm 6 cm 5 cm we need to find the area of the figure,

Since, we can see that the figure is a composite figure, we will first split the figure and find the area of each part separately then, add all of them,

The figure is consisting of two rectangles, with dimensions, 4 cm and 6 cm and the second one with dimensions, 5 cm and 3 cm,

so, the area of the rectangle with dimensions, 4 cm and 6 cm = 4 x 6 = 24 cm²

And,

The area of the rectangle with dimensions, 5 cm and 3 cm = 5 x 3 = 15 cm²

The area of the figure = 15 + 24 = 39 cm²

Hence, the area of the composite figure given is 39 cm²

The reflection of the shape over the line p is drawn and added as an attachment

When a shape is reflected over a line, it is flipped across that line. The reflected image of the shape is a mirror image of the original shape, and appears to be a mirror image of the original shape.

This means that we simply flip the shape over the line of reflection

The line over which the shape is reflected is called the line of reflection, and it acts as a mirror. In this case, it is the line p. The shape and its reflected image are symmetric with respect to the line of reflection.

Flipping the shape would result in any point on the original shape and its corresponding point on the reflected image are equidistant from the line of reflection, as the distance between a point and its reflected image is equal to twice the perpendicular distance from the point to the line of reflection.

The polynomial can be written as:

f(x) = x³ - 3x² + 4x - 2

We know that the degree is 3, and two of the roots are x = 1 and x = 1 + i.

Then the last root must be 1 - i, so the polynomial is real, then if the leading coeficient of the polynomial is a, we can write:

f(x) = a*(x - 1)*(x - (1+ i))*(x - (1 - i))

Expanding that:

f(x) = a*(x - 1)*[x² -2x + 2]

f(x) = a*(x³ - 2x² + 2x - x² + 2x - 2)

f(x) = a*(x³ - 3x² + 4x - 2)

And we know that f(0) = -2, then we need to solve:

-2 = a*(0³ - 3*0² + 4*0 - 2)

-2 = a*-2

So a = 1

Final price = Original price - Coupon amount
Final price = $46 - $24
Final price = $22

For the 50% off coupon:
Final price = Original price - (Original price x Coupon percentage)
Final price = $46 - ($46 x 0.50)
Final price = $46 - $23
Final price = $23

Rounding to the nearest gram, the recommended amount of sugar in a normal diet is approximately 293 grams.

(a) The area of a triangle can be found using the formula A = (1/2)bh, where b is the base and h is the height. In this case, the base is one of the sides with length 13 or 15, and the height is the altitude with length 12. Using the formula, the area is A = (1/2)(13)(12) = 78 square units.

(b) The area of a triangle can also be found using Heron's formula, which is A = √[s(s-a)(s-b)(s-c)], where s is the semiperimeter of the triangle, and a, b, and c are the lengths of the sides. In this case, s = (10+10+16)/2 = 18, so the area is A = √[18(18-10)(18-10)(18-16)] = 80 square units.

(c) Using Heron's formula again, s = (5+12+13)/2 = 15, so the area is A = √[15(15-5)(15-12)(15-13)] = 30 square units.

(d) The area of an isosceles triangle can be found using the formula A = (1/2)bh, where b is the base and h is the height. In this case, the base is 30 and the height can be found using the Pythagorean theorem, h = √(17^2 - (30/2)^2) = 8. So the area is A = (1/2)(30)(8) = 120 square units.

(e) The area of an isosceles triangle can also be found using the formula A = (1/2)ab sin C, where a and b are the lengths of the two equal sides and C is the vertex angle. In this case, a = b = 20 and C = 68°, so the area is A = (1/2)(20)(20) sin 68° = 190.4 square units.

(f) Using the same formula as in (e), but with a = b = 30 and C = 62°, the area is A = (1/2)(30)(30) sin 62° = 675 square units.

(g) The area of a triangle inscribed in a circle can be found using the formula A = (1/2)ab sin C, where a and b are the lengths of the two sides and C is the angle between them. In this case, one side is a diameter with length 8 (2 times the radius of 4), another side has an unknown length, and the angle between them is 30°. The area is A = (1/2)(8)(b) sin 30° = 2b square units.

(h) The area of a triangle cut off by a line parallel to the base can be found using the formula A = (1/2)bh, where b is the length of the base and h is the height. In this case, the base is 10 and the height is 5 - 6 = -1, so the area is A = (1/2)(10)(-1) = -5 square units.

The limiting probabilities are π0 = 7/12 and π1 = 5/12.

Verify that this is an irreducible ergodic Markov chain.

An irreducible Markov chain is one in which it is possible to move from any state to any other state in a finite number of steps. In this case, the probability transition matrix P is:

P = [0.4 0.6]

   [0.7 0.3]

Since there are non-zero probabilities in every row and column, it is possible to move from any state to any other state in a finite number of steps. Therefore, this is an irreducible Markov chain.

An ergodic Markov chain is one in which every state is positive recurrent and aperiodic. Since this is an irreducible Markov chain, every state is positive recurrent. Additionally, there are no cycles in the transition matrix, so every state is aperiodic. Therefore, this is an ergodic Markov chain.

Compute the two step transition probability matrix P(2).

The two step transition probability matrix P(2) is obtained by multiplying the matrix P by itself:

P(2) = P * P = [0.4 0.6] * [0.4 0.6]

                  [0.7 0.3]                    [0.7 0.3]

         = [0.4*0.4 + 0.6*0.7  0.4*0.6 + 0.6*0.3]

              [0.7*0.4 + 0.3*0.7  0.7*0.6 + 0.3*0.3]

         = [0.58  0.42]

              [0.49  0.51]

Find the limiting probability π0 and π1.

The limiting probabilities are the stationary probabilities of the Markov chain, which are obtained by solving the following system of equations:

π0 = 0.4*π0 + 0.7*π1

π1 = 0.6*π0 + 0.3*π1

π0 + π1 = 1

Solving this system of equations gives:

π0 = 7/12

π1 = 5/12
