Answer:

e. Reduced conflict.

Explanation:

Outsourcing is a tool that allows you to hire a provider outside the company for the execution of secondary activities, such as cleaning or mail, or covering other areas of the company, such as financial or accounting systems or the human resources area

- Advantages of Outsourcing

- Cost reduction

- Focus on the main activity

- Transformation of fixed costs into variables

- Reduce risk

- Improve quality

- Productivity increase

- Improve innovation processes

- Greater flexibility

- Access to the latest technologies

- Increase in competitiveness

Match each method of erosion with the correct definition

Katena32 [7]

In this item, we are asked to determine the correct definition for the terms. It is unfortunate that they meanings to which we could match them are not given. With that, the answers written here are the well-researched ones.

Solution --> This type of erosion happens when the components found in the rocks (i.e. limestone) are dissolved through the acid components of acid rain.

Abrasion --> This is a process by which the rocks that are eroded to the riverbanks wear down other components of the bed.

Saltation --> This process involves the movement of the particles through a series of bounces that are short and are along the surface of the ground. This results to dislodging the other particles.

An object is projected at 25m/s from the top of a building of height 50m. At the same instant,another object is projected from t

docker41 [41]

A) The objects have the same vertical position after 2 seconds

B) The objects have same vertical position at y = 30.4 m (but they do not collide since they have different x-position)

Explanation:

The motion of the first object along the vertical direction is a uniformly accelerated motion, so we can write its position at time t using the following equation:

$y_1(t)=h+u_1 t + \frac{1}{2}gt^2$

where:

h = 50 m is the initial height

$u_1=0$ is the initial vertical velocity (the object is projected horizontally, so the vertical velocity is zero at the beginning)

$g=-9.8 m/s^2$ is the acceleration of gravity

So, its vertical position can be rewritten as

$y_1(t)=50-4.9t^2$

The position of object 2 instead can be written as

$y_2(t)=(u_2 sin \theta)t + \frac{1}{2}gt^2$

where

$u_2 sin \theta$ is the initial vertical velocity, where

$u_2 = 50 m/s$ is the initial velocity

$\theta=30^{\circ}$ is the angle of projection

Substituting, we get:

$y_2(t)=(50)(sin 30^{\circ})t+\frac{1}{2}(-9.8)t^2=25t-4.9t^2$

The two objects collide when their vertical position is the same, so:

$y_1(t)=y_2(t)\\50-4.9t^2 = 25t-4.9t^2$

And solving for t, we find:

$50=25t\\t= 2 s$

Note that this means that the two object at t = 2 s have the same vertical position: however, this is not true for the horizontal position.

In order to find the point where they collide, we have to substitute the time of the collision that we found in part A into one of the expressions of the vertical position.

Substituting into the expression of object 2, we find:

$y_2(t) = 25t-4.9t^2=25(2.0)-4.9(2.0)^2=30.4 m$
