You have recently been called to troubleshoot network connectivity problems at a user's workstation. You have found that the network cable runs across high-traffic areas on the floor, causing the cable to wear through and break. You have replaced the cable with a plenum-rated and shielded twisted pair cable. You would like to minimize the problem and prevent it from happening again.Which of the following will BEST protect the cable from further damage?A. Encase the cable in a protective shield and secure the cable to prevent it from slipping.B. Periodically check the cable for kinks and wear. Replace the cable when necessary.C. Run the cable through the ceiling area instead of across the floor.D. Run the cable under the carpet.

Answer:

The correct answer is -

19 - C) parasitism

20- B) commensalism

Explanation:

Parasitism is a type of symbiotic relationship among two different organisms where one is benefited and the other is harmed. The harmed organism known as the host and the benefitted organism called the parasite. For instance, tapeworms are parasites in the human body.

Commensalism is also a symbiotic relationship but in this relationship, one symbiont is benefitted but another one neither benefitted nor harmed. For instance, Hermit crabs use the shells of dead snails for homes.

Answer:

Total cost = #6.2

Explanation:

Given the following data;

Voltage = 240 V

Power = 40 W

Time = 62 hours

Cost = #2.50

To find the cost of running the lamp for 62 hours;

First of all, we would determine the energy consumption of the electric lamp

Energy consumption = power * time

Energy consumption = 40 * 62

Energy consumption = 2480 Watt-hour = 2.48 Kwh (1 Kilowatts is equal to 1000 watts).

Next, we would determine the cost of running the lamp;

Total cost = energy consumption * cost

Total cost = 2.48 * 2.50

Total cost = #6.2

yes their density are equal

Answer:

Gravity.” or “Gravity causes the moon to orbit the earth.” “Acceleration due to gravity” is much more precise. It is the acceleration that an object experiences when it is dropped with no other external forces on it. ... Near the surface of the earth the acceleration due to gravity is about 9.8

Answer:

Acceleration due to gravity is the rate of change in velocity of a body under the influence of gravitational fields while gravitational force is the force of one newton experinced by a body of 1 kg mass placed in gravitational fields.

Answer:

S:V = 1 : 2

Explanation:

Given the following data;

Surface area, S = 432 m²

Volume, V = 864 m³

To find the ratio of surface area to volume for a sphere;

The ratio of two or more numbers are determined by reducing the numbers to their nearest minimum i.e dividing all through by the same or common number.

S:V = 432 : 864

Dividing both sides by 432, we have;

S:V = 432/432 : 864/432

S:V = 1 : 2

Answer:

The final position is  (2, 7)m

Explanation:

When we work with coordinate pairs, the addition works as:

(a, b) + (c, d) = (a + c, b + d)

So, for example, if we start at (a, b), and we have a displacement d = (1, 1)

we just need to solve:

(a, b) + (1, 1) = (a + 1, b + 1)

Now, in this case, we start at (4, 4)m

first, we have d1 = (2, -3) m

After this displacement, the position is:

(4, 4)m + (2, -3)m = (4 + 2, 4 - 3)m = (6, 1)m

Now we have a displacement d2 = (-5, 0) m

After this, the position is:

(6, 1)m + (-5, 0)m = (6 -5, 1 + 0)m = (1, 1)m

After this, we have the final displacement d3 = (1, 6) m, so the final position will be:

(1, 1)m + (1, 6)m = (1 + 1, 1 + 6)m = (2, 7)m

Below you can see a rough sketch of the path that the student take, where he/she starts at point A.

Answer:

0.6 A

Explanation:

Applying,

I = E/(R'+r).................... Equation 1

Where I = curent or circuit supply, R'= equivalent external resistance, r = internal resistance.

From the question,

Given: E = 12 Volt,

IF the three resistors are connected in series, R' = (3+7+10) ohm = 20 ohm,

r = neglible.

Substitute these values into equation 1

I = 12/(20)

I = 0.6 A

Answer:

The magnitude of the force between the charges is approximately -2,858.77 N

Explanation:

The given details are;

The magnitude of the given charges;

q₁ = -0.00125 C, q₂ = +0.00333 C

The distance between the charges, r = 3.62 m

The magnitude of the electric force between the charges, 'F', between two charged particles or objects is given as follows;

[tex]F = \dfrac{k \cdot q_1 \cdot q_2}{r^2}[/tex]

Where;

k = Constant = 9 × 10⁹ N·m²/C²

q₁ = The magnitude of charge on the first charged object = -0.00125 C

q₂ = The magnitude of charge on the second charged object = +0.00333 C

r = The distance between the charges = 3.62 m

Plugging in the values, gives;

[tex]F = \dfrac{9 \times 10^9 \ \dfrac{N \cdot m^2}{C^2} \times (-0.00125 \, C) \times (+0.00333 \, C)}{\left( 3.62 \, m \right)^2} \approx -2,858.77 \, N[/tex]

The magnitude of the force between the charges, F ≈ -2,858.77 N

Answer:

The density of the mixture is 0.775 g/cm³

Explanation:

The given parameters are;

The mass of the alcohol, m₁ = 21 g

The density of the alcohol, ρ₁ = 0.7 g/cm³

The mass of the water with which the alcohol is mixed, m₂ = 10 g

The density of wate, ρ₂ = 1.0 g/cm³

The density of a substance is given by the ratio of the mass to the volume of the substance

The density of the mixture, ρ is given as follows;

[tex]\rho = \dfrac{m_1 + m_2}{\dfrac{m_1}{\rho_1} + \dfrac{m_2}{\rho_2} }[/tex]

Therefore;

[tex]\rho = \dfrac{21 + 10}{\dfrac{21}{0.7} + \dfrac{10}{1.0} } = 0.775[/tex]

The density of the mixture, ρ = 0.775 g/cm³.

Answer:

V²=U² + 2as

Where V=Final Velocity

U=Initial Velocity

a=acceleration ( Deceleration in this case)

s=distance covered

10² = 30² + 2(a)(20)

100 = 900 + 40a

100 - 900 = 40a

-800=40a

a= -800/40

a= -20ms-².

Its negative because the car Decelerated.

Answer:

Acceleration is the rate of change of velocity. What is commonly said as ‘ten meter per second squared’ can bee broken down into ‘ten meter per second per second.’ This gives us the true meaning of the term acceleration.

Just like ‘ten meter per second’ means increasing the displacement by ten meters every second, ‘ten meter per second per second’ means increasing the velocity by ten meters per second every second.

So, basically if you consider the case of a free fall motion, where ‘t’ stands for time and ‘v’ stand for velocity at that instant:

At,

t=0, v=0 m/s

t=1, v=0+10 m/s;

t=2, v=0+10+10 m/s;

t=3, v=0+10+10+10 m/s;

This can also be thought as a Arithmetic Progression where common difference ‘D’ is the acceleration(a), since it adds a 10 m/s to velocity every second and the first term ‘A’ stands for the initial velocity (u). Using this approach we can derive to the first equation of motion:

v = u + at

Answer:Whenever the velocity of the object increases or usually doubles, the kinetic energy will be quadrupled. If in case you are not familiar with kinetic energy, this is known as the type of energy that is in motion. The greater the mass of the object, the greater the total of the energy

Explanation:

Change to an object would quadruple its kinetic energy Increasing its velocity to twice its original value

In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest. Formally, kinetic energy is any term in a system's Lagrangian which includes a derivative concerning time.

In classical mechanics, the kinetic energy of a non-rotating object of mass m traveling at a speed v is [tex]{\textstyle {\frac {1}{2}}mv^{2}}[/tex]

In relativistic mechanics, this is a good approximation only when v is much less than the speed of light.

The standard unit of kinetic energy is the joule, while the English unit of kinetic energy is the foot-pound.
