The volume of the dilated prism (with a volume of 450 ft³ is dilated by a factor of 2) = 3600 ft³

The volume of the dilated prism will be 8 times the volume of the original prism. This is because the volume of a prism is related to its linear dimensions by the formula:

V = lwh

Where.

V is the volume

l is the length

w is the width, and

h is the height.

When a prism is dilated by a factor of 2, each of its linear dimensions is multiplied by 2, so the volume will be multiplied by 2³, or 8.

Therefore, the volume of the dilated prism will be 450 ft³ × 8

= 3600 ft³.

So the answer is 3600 ft³.

Answer:

\(\boxed {\boxed {\sf 2.7 \ m/s^2}}\)

Explanation:

Force is the product of mass and acceleration.

\(F=ma\)

The mass of the object is 2.3 kilograms. The force is 6.2 Newtons or 6.2 kilogram meters per second squared.

Substitute the values into the formula.

\(6.2 \ kg*m/s^2 = 2.3 \ kg *a\)

We are solving for the acceleration, so we must isolate the variable a.

It is being multiplied by 2.3 kilograms. The inverse operation of multiplication is division. Divide both sides by 2.3 kg.

\(\frac {6.2 \ kg*m/s^2}{2.3 \ kg} = \frac{2.3 \ kg *a}{2.3 \ kg}\)

\(\frac {6.2 \ kg*m/s^2}{2.3 \ kg} =a\)

\(2.69565217 \ m/s^2=a\)

The original measurements of force and mass have 2 significant figures, so our answer must have the same. For the number we found, that is the tenths place. The 9 in the hundredht place tells us to round the 6 up to a 7.

\(2.7 \ m/s^2 \approx a\)

The acceleration is approximately 2.7 meters per second squared.

The probability that she is correct on only two questions is 0.246

Explanation:

The probability of getting an answer correct = 1/5

The probability of getting only two questions correctly

By binomial trials, we have;

P(X = K) = \(\dbinom{n}{k}\times p^{k}\times \left (1 - p \right )^{n - k}\)

P(X = 2) = \(\dbinom{6}{2}\times \left (\dfrac{1}{5} \right )^{2}\times \left (1 - \dfrac{1}{5} \right )^{6 - 2}\)

= 15×256/15625 = 768/3125 = 0.246

Therefore, the probability that she is correct on only two questions = 0.246.

Answer:

0.05s

Explanation:

frequency = speed / wavelength = 20/1 = 20Hz. Thus period = 1/f = 1/20 = 0.05 s

This question involves the concepts of wave speed and wavelength.

The period of the wave is "0.05 s".

The wave speed is given in terms of wave frequency and wavelength as follows:

\(v=f\lambda\\\\f=\frac{v}{\lambda}\)

where,

Therefore,

\(f=\frac{20\ m/s}{1\ m}\\\\\)

f = 20 Hz

The value that would change the most if 27 were added to the set is the mean.

To determine the effect of adding 27 to the set on mean, median, and mode, let's calculate each measure before and after the addition.

Before adding 27:

Mean = (74 + 44 + 81 + 78 + 84 + 74 + 9942) / 7 = 1465.57

Median = 78

Mode = 74

After adding 27:

Mean = (74 + 44 + 81 + 78 + 84 + 74 + 9942 + 27) / 8 = 1479.5

Median = 78

Mode = 74

The mean value changed the most, increasing from 1465.57 to 1479.5. The median and mode remain the same because they are not affected by adding a value that is not larger than the current maximum value.

The apparent weight of the pilot at the lowest point of the pullout 1040 N.

The centripetal force, F = mv²/r, where m is the mass of the pilot, v is her speed, and r is the radius of the circle. At the lowest point of the pullout, the radius of the circle is equal to the distance from the center of the circle to the point where the plane changes direction (i.e., the height above the ground).

Since the plane is diving vertically, the initial speed is, v₀ = √(2gh), where h is the initial height of the plane above the ground, and g is the acceleration due to gravity. At the lowest point of the pullout, all of the potential energy that the plane had at the start of the dive is converted into kinetic energy. Therefore, the speed, v = √(2gh).

Substituting the expressions for v and r into the expression for the centripetal force,

F = m * (2gh) / (2h) = mg

Therefore, the apparent weight of the pilot at the lowest point of the pullout is twice her actual weight,

By resolving forces into their components and adding them together, you can determine the resultant force in the x and y directions without knowing the actual variables involved.

To find the summation of Fx and summation of Fy without knowing the specific variables, you need to have information about the forces acting on an object in the x and y directions. If you have the magnitudes and directions of individual forces, you can use vector addition to determine the resultant force in each direction.

Here's a general approach to finding the summation of Fx and Fy:

Identify the forces: Start by identifying all the forces acting on the object and their directions. Each force can be represented as a vector with a magnitude and direction.

Resolve forces: If the forces are not already given in the x and y directions, you need to resolve them into their x and y components. Use trigonometry (sine and cosine) to determine the components of each force along the x-axis (Fx) and the y-axis (Fy).

Sum the components: Add up all the individual components of forces acting in the x-direction to find the summation of Fx. Similarly, add up all the individual components of forces acting in the y-direction to find the summation of Fy.

Summation of Fx = F1x + F2x + F3x + ...

Summation of Fy = F1y + F2y + F3y + ...

Combine components: If there are forces acting at an angle to the x and y axes, you can use the Pythagorean theorem and trigonometry to find the resultant force in each direction.

Summation of Fx = √(F1x^2 + F2x^2 + F3x^2 + ...) (taking into account both magnitudes and directions)

Summation of Fy = √(F1y^2 + F2y^2 + F3y^2 + ...) (taking into account both magnitudes and directions)

A dihybrid cross resulting in a 9:3:4 ratio suggests that the traits being studied are controlled by two different genes that are segregating independently.

In genetics, a dihybrid cross involves the mating of individuals that differ in two traits controlled by different genes. When analyzing the offspring of such a cross, the observed ratio of phenotypes can provide information about the inheritance patterns of these traits.

A 9:3:4 ratio indicates that there are three distinct phenotypic classes, and the numbers in the ratio represent the proportions of each phenotype observed in the offspring. This ratio suggests that the two genes responsible for the traits under consideration are segregating independently, meaning that the inheritance of one trait does not influence the inheritance of the other.

The ratio can be further interpreted as follows: 9 individuals display the dominant phenotype for both traits, 3 individuals display the dominant phenotype for one trait and the recessive phenotype for the other trait, and 4 individuals display the recessive phenotype for both traits.

Overall, the 9:3:4 ratio resulting from a dihybrid cross suggests independent segregation of two genes controlling the traits, with the observed phenotypic ratios reflecting the combinations of dominant and recessive alleles for each gene.

Plugging in the values, we get T = 2π√(2/9.81) ≈ 2.02 seconds.

b. If the length of the pendulum is doubled to 4m, we can use the same formula to find the new period. Plugging in the new value for L, we get T = 2π√(4/9.81) ≈ 4.04 seconds. So doubling the length of the pendulum results in a doubling of the period.

c. If the length of the pendulum is shortened back to 2m, but the mass is doubled to 6kg, we can again use the same formula to find the new period. Plugging in the new values for L and the mass, we get T = 2π√(2/9.81) ≈ 1.43 seconds. So doubling the mass while keeping the length constant results in a shorter period.

1. The direction of the magnetic field at the center of the loop is perpendicular to the plane of the loop and follows the right-hand rule.

The right-hand rule states that if you curl the fingers of your right hand in the direction of the current flow in a loop, your thumb will point in the direction of the magnetic field at the center of the loop. The magnetic field lines are circular and perpendicular to the plane of the loop.

2. The expression for the magnitude of the magnetic field at the center of the arc can be calculated using the formula for the magnetic field due to a circular loop of wire. The expression is given by: B = (μ₀ * I) / (2 * r), where B is the magnetic field, μ₀ is the permeability of free space, I is the current in the loop, and r is the radius of the arc.

The magnetic field at the center of the arc formed by the right-angle bend in the wire can be calculated using the formula for the magnetic field due to a circular loop of wire. The magnetic field strength is directly proportional to the current in the loop (I) and inversely proportional to the radius of the arc (r). The permeability of free space (μ₀) is a constant value. By plugging in the values of current and radius, the expression for the magnitude of the magnetic field at the center of the arc can be determined.

3. The force per unit length between two parallel wires carrying current can be calculated using the formula: F/L = (μ₀ * I₁ * I₂) / (2 * π * d), where F/L is the force per unit length, μ₀ is the permeability of free space, I₁ and I₂ are the currents in the wires, and d is the distance between the wires.

The force per unit length between two parallel wires carrying current can be calculated using the formula above. The force is directly proportional to the product of the currents in the wires (I₁ and I₂) and inversely proportional to the distance between the wires (d). The permeability of free space (μ₀) is a constant value.

4. The force between two parallel wires depends on the direction of the currents. If the currents are in the same direction, the force is repulsive, and if the currents are in opposite directions, the force is attractive.

The direction of the currents in the two parallel wires determines the direction of the magnetic fields around the wires. When the currents flow in the same direction, the magnetic fields around the wires interact and result in a repulsive force between the wires. When the currents flow in opposite directions, the magnetic fields interact differently and result in an attractive force between the wires.

5. To find the current in the other wire when two parallel wires separated by a distance carry a force per unit length, the formula can be rearranged to solve for the current in the second wire, I₂ = (F/L) * (2 * π * d) / (μ₀ * I₁), where I₂ is the current in the second wire, F/L is the force per unit length, d is the distance between the wires, μ₀ is the permeability of free space, and I₁ is the current in the first wire.

By rearranging the formula for the force per unit length between two parallel wires, the current in the second wire (I₂) can be calculated. The force per unit length (F/L), the distance between the wires (d), and the current in the first wire (I₁) are known quantities, and the permeability of free space (μ₀) is a constant value.
