Answer: 16 meters; -4 meters

Explanation:

For this question, you can ignore the times that were given to you.

a.) Let's start with distance. Distance is a total sum, regardless of direction. This student walked 6 meters, stands still (0 meters), 3 meters, and 7 meters. Sum up these values: 6+0+3+7 = 16 meters

b.) Displacement adds direction. The student walks 6 meters away. We will give this the +x-direction. They then walk 3 meters back towards the origin (-x-direction) and pause for a second. They continue to walk 7 more meters toward the origin (-x-direction). This time when we sum these values we must include the signs: 6+(-3)+(-7) = -4 meters. We can test this by referring to the sentence where it says they passed their starting point. This means they are now in the -x-direction and we have a negative displacement.

An excellent green, eco-friendly substitute is coconut coir, a byproduct of coconuts. Due to its ability to clean without endangering the ecosystem, coir is becoming increasingly popular and adopted.

The shell of the coconut is known as coco coir. It is immersed in water for a few weeks after extraction to help it loosen and soften. The husk is then dried, brushed, and turned into a product that resembles fibre but is much stronger. Because of the product's durability, stretching or compressing it in any way won't harm it.
Fine brushes, ropes, beds, upholstery, and fishnets are all made from white coco coir, which is extracted from unripe coconuts.

Brown coco coir is pressed from ripe coconuts and used to create mats, pots, and scrubbers that resemble discs for cleaning kitchen surfaces and utensils. In the kitchen, these naturally antimicrobial items are preferable to plastic scrubbers. When they begin, they can be recycled as an organic planting substrate because they are not toxic.

Answer:

0.63m/s²

Explanation:

The average acceleration can be derived from using the formula:

V = u + at

Where v = final velocity (m/s)

u = initial velocity (m/s)

a = acceleration (m/s²)

t = time (s)

V = u + at

V - u = at

a = v - u/t

a = ∆V/t

According to the provided information; v = 5.8m/s, u = 0m/s, t = 9.25s

a = ∆V/t

a = (5.8-0)/9.25

a = 5.8/9.25

a = 0.627

a = 0.63m/s²

Hence, the average acceleration is 0.63m/s²

The average acceleration of the ferry which leaves Guemes Island and heads back  toward Anacortes is 0.627m/s².

Given the data in the question;

To determine the average acceleration, we use the first equation of motion:

\(v = u + at\)

Where v is final speed, u is initial speed, a is acceleration and t is time taken.

We substitute our given values into the equation

\(5.8m/s = 0 + [ a * 9.25s ]\\\\5.8m/s = a * 9.25s\\\\a = \frac{5.8m/s}{9.25s}\\\\a = 0.627m/s^2\)

Therefore, the average acceleration of the ferry which leaves Guemes Island and heads back  toward Anacortes is 0.627m/s².

The magnitude of the average force is -1.5×10³ N.

What is force?

A force is any action that seeks to preserve, modify, or deform a body's motion.

We know,

The magnitude of the average force is:

F = m(v-u)/t

F = Average force

m = mass of the cyclist

v = Final velocity

u = Initial velocity

t = time.

Putting values into the formula

F = 50(0-10)/0.5

F = -1500 N

F = -1.5×10³ N

The negative sign is the force act against the motion of the cyclist.

The best description of the bottleneck resource for a process is: It is the resource that takes the longest time.

In process management, a bottleneck refers to a point in the process where the flow of work is limited or constrained, causing a delay in the overall process. The bottleneck resource is the specific resource (such as a machine, equipment, or person) that has the longest processing time compared to other resources in the process.

The presence of a bottleneck resource can significantly impact the efficiency and throughput of the entire process. Since the bottleneck resource takes the longest time to complete its tasks, it creates a bottleneck effect by limiting the overall capacity of the process. The output of the process cannot exceed the capacity of the bottleneck resource, which can lead to waiting times, delays, and inefficiencies in the process.

Identifying and managing the bottleneck resource is crucial for optimizing process performance. Strategies such as increasing the capacity of the bottleneck resource, balancing workloads, improving efficiency, or redesigning the process flow can help alleviate the bottleneck and improve the overall productivity of the process.

The mass of Deimos is approximately 9.52 x 10^15 kg.

To find the mass of Deimos, we can use the formula for gravitational force:F = G * (m1 * m2) / r^2. where F is the gravitational force between two objects, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers of mass.

In this problem, we know the radius of Deimos (r = 6.3 km = 6.3 x 10^3 m), the mass of the rock on its surface (m1 = 3.0 kg), and the gravitational force between them (F = 2.5 x 10^-2 N). We can also look up the value of G: G = 6.674 x 10^-11 N(m/kg)^2.

We want to solve for the mass of Deimos (m2). Rearranging the formula, we get: m2 = (F * r^2) / (G * m1). Substituting the given values, we get: m2 = (2.5 x 10^-2 N) * (6.3 x 10^3 m)^2 / (6.674 x 10^-11 N(m/kg)^2 * 3.0 kg). m2 = 9.52 x 10^15 kg.Therefore, the mass of Deimos is approximately 9.52 x 10^15 kg.

It is worth noting that this calculation assumes that the rock on Deimos' surface is not affecting its orbit significantly. In reality, the gravitational force between the rock and Deimos would cause some perturbations in Deimos' orbit, but they are likely to be very small due to the small mass of the rock compared to Deimos.

To find the mass of Deimos, we can use the gravitational force formula:
F = G * (m1 * m2) / r^2

Where F is the gravitational force (2.5 * 10^(-2) N), G is the gravitational constant (6.674 * 10^(-11) Nm^2/kg^2), m1 is the mass of Deimos (which we want to find), m2 is the mass of the rock (3.0 kg), and r is the distance between their centers, which is equal to Deimos' radius (6.3 km or 6300 m).

Rearranging the formula to solve for m1 (the mass of Deimos):

m1 = (F * r^2) / (G * m2)

m1 = (2.5 * 10^(-2) N * (6300 m)^2) / (6.674 * 10^(-11) Nm^2/kg^2 * 3.0 kg)

The tension in the lower segment of the belt is 219 N. To find the tension in the lower segment of the belt, we can start by analyzing the forces acting on the flywheel.

The net torque acting on the flywheel can be expressed as the product of its moment of inertia and angular acceleration, given by the equation:

\(\[ \tau = I \alpha \]\)

Since the axle is frictionless, the only torque acting on the flywheel is due to the tension in the lower segment of the belt. The moment of inertia of a solid disk can be calculated using the equation:

\(\[ I = \frac{1}{2} m r^2 \]\)

where m is the mass of the flywheel and r is its radius. Substituting this into the torque equation, we have:

\(\[ T_{\text{u}} \cdot r_{\text{pulley}} = \frac{1}{2} m r^2 \cdot \alpha \]\)

Rearranging the equation, we can solve for the tension in the lower segment of the belt:

\(\[ T_{\text{u}} = \frac{1}{2} \frac{m r^2 \alpha}{r_{\text{pulley}}} \]\)

Plugging in the given values, with the mass of the flywheel (m = 66.5 kg), radius of the flywheel (r = 0.625 m), radius of the pulley \((r_{\text{pulley}} = 0.230 m)\), and the angular acceleration \((\alpha = 1.67 rad/s^2)\), we can calculate the tension in the lower segment of the belt:

\(\[ T_{\text{u}} = \frac{1}{2} \frac{66.5 \cdot 0.625^2 \cdot 1.67}{0.230} = 219 \, \text{N} \]\)

Answer:

Explanation:

The sum of all the forces acting on an object is the net force or resultant force. If all the forces cancel out, the resultant force is zero, else, the unbalanced force will cause acceleration of the object. Force is a vector and hence has both a direction and magnitude. For example, gravitational force (on earth) acts in downward direction and has a magnitude equal to mass of the object and acceleration due to gravity. Once we know all the forces that are acting on a body, we resolve all of them into components (typically horizontal and vertical) and take summation of forces in each direction. If such forces cancel out (in each direction), the object maintains its state of rest or constant motion. If however, forces do not cancel out, there is a net resultant force on the object that will cause acceleration of the object (as given by Newton's second law of motion).  

Hope this helps.

The sum of all of the forces acting on an object is called net force. It is categorized as a vector quantity because it has both direction and magnitude to be considered.

Force may be defined as the process of pushing or pulling on an object with mass provoking it to change its velocity. It is an external agent capable of altering a body's state of rest or motion. It has a magnitude and a direction, so it is a vector quantity.

Net force in a case where forces of different magnitude and opposite directions will be the difference between greater and lesser force. The combination of the resultant of all the forces acting on an object is called Net Force, which is basically the sum of all the forces acting on that object.

Therefore, the sum of all of the forces acting on an object is called net force.
