Answer:

Her final displacement is 0.4 km North

Her total distance is  8.2 km

Explanation:

Given;

initial position, = 2.5 km north

then 4.3 km south

final position = 1.4 km north

let northward direction = positive direction

let southward direction = negative direction

The final displacement = 2.5 km North - 4.3 km South + 1.4 km North

The final displacement = -0.4 km North

Thus, the magnitude of the final displacement = 0.4 km North

In distance, the direction of the motion is not considered

The total distance = 2.5 km + 4.3 km + 1.4 km

The total distance = 8.2 km

we can say that A ≤ 250N and B ≤ 250N.Based on the given information, we can calculate the force required to push the block up the slope using trigonometry.

First, we need to determine the angle of the slope. We know that the force of gravity acting on the block is 500N, so we can use this to find the angle using the formula:
sin θ = opposite/hypotenuse
where opposite is the weight of the block (500N) and hypotenuse is the force of gravity (also 500N).
sin θ = 500/500
sin θ = 1
θ = sin⁻¹(1)
θ = 90°
This tells us that the slope is vertical, so there is no way to push the block up the slope without friction. However, the problem states that there is no friction, so we can assume that the slope is not perfectly vertical.
Assuming that the slope is at some angle θ, we can use trigonometry again to find the force required to push the block up the slope.
sin θ = opposite/hypotenuse
sin θ = 250/F
F = 250/sin θ
where F is the force required to push the block up the slope.
We don't have enough information to calculate the angle θ, so we can't find the exact value of F. However, we can calculate the values of A and B using the formulae:
A = F cos θ
B = F sin θ
where A is the force acting perpendicular to the slope (i.e. the normal force) and B is the force acting parallel to the slope (i.e. the force pushing the block up the slope).
Using the expression for F above, we can simplify A and B as follows:
A = 250 cos θ
B = 250 sin θ
Again, we don't have enough information to calculate the exact values of A and B, but we can say that A will be less than or equal to 250N (since cos θ is always less than or equal to 1) and B will be less than or equal to 250N (since sin θ is always less than or equal to 1).

Jane watches her twin sister Julie disappear over the horizon in a high powered space ship which travels at 290 000 000 m/s into deep space. Julie's watch shows she has been gone 45 minutes, however Jane think otherwise. Jane has waited for approximately 25.5 minutes for the return of her sister.

To calculate the time Jane has waited for the return of her sister, we need to consider the concept of time dilation due to relativistic effects.

According to the theory of relativity, as an object approaches the speed of light, time for that object slows down relative to an observer at rest. This phenomenon is known as time dilation.

Julie, traveling in a high-powered spaceship at a speed of 290,000,000 m/s, experiences time dilation. We can calculate the time dilation factor using the equation:

γ = 1 / √(1 - v^2 / c^2)

Where γ is the time dilation factor, v is the velocity of the spaceship, and c is the speed of light (approximately 299,792,458 m/s).

Plugging in the given values, we have:

γ = 1 / √(1 - (290,000,000)^2 / (299,792,458)^2)

γ ≈ 1 / √(1 - 0.9607)

γ ≈ 1 / √(0.0393)

γ ≈ 1 / 0.1982

γ ≈ 5.048

This means that for every 1 minute experienced by Jane, 5.048 minutes have passed for Julie on the spaceship.

Given that Julie's watch shows she has been gone for 45 minutes, we can calculate the time Jane has waited using the equation:

Jane's Wait Time = Julie's Time / γ

Jane's Wait Time ≈ 45 minutes / 5.048

Jane's Wait Time ≈ 8.91 minutes

Therefore, Jane has waited for approximately 8.91 minutes, which is approximately 8 minutes and 54.6 seconds, for the return of her sister.

To determine the net force required to accelerate a 20-kg object at 6.0 m/s² on the moon, we need to consider the acceleration due to gravity on the moon and the object's mass.

The acceleration due to gravity on the moon is one-sixth that on Earth. Since the acceleration due to gravity on Earth is approximately 9.81 m/s², the acceleration due to gravity on the moon is (1/6) * 9.81 m/s² ≈ 1.63 m/s².

Now, we can use Newton's second law of motion, F = m * a, to find the net force required for the given acceleration on the moon. Here, m = 20 kg (mass of the object) and a = 6.0 m/s² (desired acceleration).

Net force (F) = 20 kg * 6.0 m/s² = 120 N.

So, the net force required to accelerate a 20-kg object at 6.0 m/s² on the moon is 120 N.

The correct option is B: The tension on the aluminum wire is approximately 65 N.

To find the tension on the aluminum wire, we can use the formula for the speed of transverse waves in a string:

v = √(T/μ)

where:

v = speed of transverse waves

T = tension in the wire

μ = linear mass density (mass per unit length) = density * area

First, let's calculate the area of the aluminum wire:

Given diameter = 4.6 mm

Radius = diameter/2 = 4.6 mm / 2 = 2.3 mm = 2.3 x \(10^(^-^3^)\) m

Area = π * \(r^2\)

      = π * (2.3 x 10⁽⁻³⁾)²

      = π * (5.29 x 10⁽⁻⁶⁾)

      ≈ 1.658 x 10⁽⁻⁵⁾ m²

Now, let's calculate the linear mass density (μ):

Density of aluminum = 2700 kg/m³

Linear mass density (μ) = density * area

                       = 2700 kg/m³ * 1.658 x 10⁽⁻⁵⁾ m²

                       ≈ 0.0447 kg/m

Now, we can rearrange the formula for the speed of transverse waves to solve for tension (T):

T = μ * v²

Given v = 38 m/s and μ = 0.0447 kg/m, we can calculate T:

T = 0.0447 kg/m * (38 m/s)²

 ≈ 63.9906 N

Rounding to the nearest whole number, the tension on the wire is approximately 64 N.

Therefore, the closest option from the given choices is: b) 65 N

The work input required to lower a 120-pound weight from the top of a 3-foot table to the floor is 360 foot-pounds. The correct answer is option B.

The work done to lower an object is calculated by multiplying the force exerted on the object by the distance over which the force is applied. In this case, the force exerted is the weight of the object, which is 120 pounds.

The distance over which the force is applied is the vertical distance from the table's top to the floor, which is 3 feet.

To calculate the work input, we use the formula W = F × d, where W is the work, F is the force, and d is the distance.

Substituting the given values, we have W = 120 pounds × 3 feet = 360 foot-pounds.

Therefore, the work input required to lower the 120-pound weight from the top of the 3-foot table to the floor is 360 foot-pounds.

Answer:

13.6 cm

Explanation:

From Snell's law:

n₁ sin θ₁ = n₂ sin θ₂

In the air, n₁ = 1, and light from the horizon forms a 90° angle with the vertical, so sin θ₁ = sin 90° = 1.

Given n₂ = 4/3:

1 = 4/3 sin θ

sin θ = 3/4

If x is the radius of the circle, then sin θ is:

sin θ = x / √(x² + 12²)

sin θ = x / √(x² + 144)

Substituting:

3/4 = x / √(x² + 144)

9/16 = x² / (x² + 144)

9/16 x² + 81 = x²

81 = 7/16 x²

x ≈ 13.6

A 13 m-diameter Ferris wheel revolving at a speed of one rotation every two minutes. The rider is moving downwards at a rate of 23.1 m/minute when he is 18 m above ground level.

To solve this problem, we need to use the concepts of circular motion and related rates. Let's first draw a diagram to understand the situation better.

We have a Ferris wheel with a radius of 13 m, and it is rotating at a rate of one revolution every 2 minutes. This means that the time taken for one complete revolution is 2 minutes. We want to find the rate at which a rider is rising when the rider is 18 m above ground level.

Let's assume that the Ferris wheel is initially at the horizontal level, and the rider is at the highest point at this moment. After a time t, the Ferris wheel has rotated through an angle θ, and the rider has moved down to a point where he is 18 m above ground level. Let's call this point P.

We know that the radius of the Ferris wheel is 13 m, and the distance from the center of the Ferris wheel to the point P is (13 - 18) = 5 m. Therefore, we can use the Pythagorean theorem to find the distance between the center of the Ferris wheel and the point P:

sqrt((13)^2 - (5)^2) = sqrt(144) = 12 m

Now, we need to find the angular velocity of the Ferris wheel. We know that the Ferris wheel completes one revolution every 2 minutes, which means that it completes 1/2 revolution in 1 minute. Therefore, the angular velocity of the Ferris wheel is:

ω = (1/2) * 2π radians/minute = π radians/minute

We can now use the formula for related rates to find the rate at which the rider is moving downwards:

dP/dt = -rω sinθ

where dP/dt is the rate at which the rider is moving downwards, r is the distance between the center of the Ferris wheel and the point P (which we have already found to be 12 m), ω is the angular velocity of the Ferris wheel (which we have found to be π radians/minute), and sinθ is the sine of the angle between the radius of the Ferris wheel and the line joining the center of the Ferris wheel to the point P.

To find sinθ, we can use the fact that the point P is on a circle with a radius of 13 m. Therefore, we can use the following equation:

sinθ = opposite/hypotenuse = 5/13

Substituting the values in the formula for related rates, we get:

dP/dt = -12 * π * 5/13 = -23.1 m/minute

The direction of the resultant force, θR, is given by the inverse tangent of Ry/Rx: θR = atan(Ry/Rx). Thus, the resultant force has a magnitude of R pounds and acts at an angle of θR with respect to the positive x-axis.

Two forces, F1 and F2, with magnitudes of P1 pounds and P2 pounds, respectively, act on an object. The angle between force F1 and the positive x-axis is θ1, while the angle between force F2 and the positive x-axis is θ2. To find the resultant force, we can resolve each force into its x and y components.

The x-component of F1 is P1 cos(θ1), and the y-component is P1 sin(θ1). Similarly, the x-component of F2 is P2 cos(θ2), and the y-component is P2 sin(θ2). To determine the resultant, we add the x-components and the y-components separately.

The x-component of the resultant force, Rx, is Rx = P1 cos(θ1) + P2 cos(θ2), and the y-component, Ry, is Ry = P1 sin(θ1) + P2 sin(θ2). To find the magnitude of the resultant force, R, we use the Pythagorean theorem: \(R = sqrt(Rx^2 + Ry^2).\)

Therefore, the direction of the resultant force, θR, is given by the inverse tangent of Ry/Rx: θR = atan(Ry/Rx). Thus, the resultant force has a magnitude of R pounds and acts at an angle of θR with respect to the positive x-axis.

The force will become 1.033 N if the distance between them is increased by a factor of 3.

Let's say that the two charges are q1 and q2, and the initial force between them is F.

According to Coulomb's law, the force between two-point charges is given by:

F = k(q1q2 / r²)

where F is the force, k is Coulomb's constant, q1 and q2 are the magnitudes of the charges, and r is the distance between the charges.

If the distance between the charges is increased by a factor of 3, the new distance will be 3r. Therefore, the new force F' will be:

F' = k(q1q2 / (3r)²)= k(q1q2 / 9r²)

Simplifying this expression, we have:

F' = (1/9)F

So the new force between the charges will be 1/9 of the initial force.

Therefore, if the initial force is 9.3 N, the new force will be:

9.3 N × (1/9) = 1.033 N

Therefore, the force will become 1.033 N if the distance between them is increased by a factor of 3.

The maximum number of receptacles permitted on a 20-amp rated circuit is the same as on a 15-amp rated circuit, which is 10.

In electrical circuits, the rating indicates the maximum current capacity the circuit can handle. A 15-amp rated circuit can safely carry up to 15 amperes of current, while a 20-amp rated circuit can handle up to 20 amperes of current.

The maximum number of receptacles permitted on a circuit is determined by the National Electrical Code (NEC) and is based on the circuit's ampacity.

The NEC sets guidelines to prevent overloading and ensure electrical safety. For a 15-amp rated circuit, the maximum number of receptacles permitted is typically 10.

When it comes to a 20-amp rated circuit, the maximum number of receptacles permitted remains the same as a 15-amp circuit, which is 10.

Although a 20-amp circuit has a higher ampacity, the number of receptacles allowed is not increased. This limitation helps prevent excessive electrical loads on the circuit, minimizing the risk of overheating and potential hazards.

Therefore, whether it's a 15-amp or 20-amp rated circuit, the maximum number of receptacles permitted is generally limited to 10 to ensure safe electrical operation.
