What is an appraisal of an employee's performance in the workplace?
Diano4ka-milaya [45]

Answer:

B. evaluation

Explanation:

An employee can be defined as an individual who is employed by an employer of labor to perform specific tasks, duties or functions in an organization.

Basically, an employee is saddled with the responsibility of providing specific services to the organization or company where he is currently employed while being paid a certain amount of money hourly, daily, weekly, or monthly depending on the contractual agreement between the two parties (employer and employee).

Hence, while an employer may be the owner of a business firm or company, an employee is a subordinate employed to provide unwavering services to the employer while also, being professional and diligent at all times.

Human resources management (HRM) can be defined as an art of managing, controlling and improving the number of people (employees or workers), functions, evaluation of employees, activities which are being used effectively and efficiently by an organization.

Hence, human resources managers are saddled with the responsibility of recruiting, evaluating, managing and improving the welfare and working conditions of the employees working in an organization.

Basically, the human resources manager carry out appraisals on the performance of the various employees working in an organization. These informations about employees are typically used for promotional purposes, allowances and other benefits or form of rewards.

Find the sum of the vectors:11 km N ,11km E
vladimir1956 [14]

The resultant vector is 11√2 km due north east.

<h3><u>Explanation:</u></h3>

The vector is a type of quantity which has both magnitude and direction. This quantities when expressed needs to specify both magnitude and direction.

We need to calculate the magnitude and direction separately.

Here firstly for the magnitude,

The magnitudes are both 11 km and they are at right angles to each other.

So, the resultant magnitude = √(11² +11²) km

=11√2 km

Now for the direction, one vector is due north and the other is due east.

So the resultant vector is due north east.

So the final vector is 11√2 km due North-East.

Imagine you are holding a box in your hand, the force required for you to hold the box with mass 4.54kg and you want to accelera
svetlana [45]

Answer:

(a) Fₓ = 0 N

F_y = 9.08 N

(b)

(a) Fₓ = 0 N

<u></u>F_y = 9.08 N

(c) F_y = 0 N

Fₓ = 9.08 N

Explanation:

The magnitude of the force will remain the same in each case, which is given as follows:

F = ma (Newton's Second Law)

where,

F = force = ?

m = mass = 4.54 kg

a = acceleration = 2 m/s²

Therefore,

F = (4.54 kg)(2 m/s²)

F = 9.08 N

Now, we come to each scenario:

(a)

Since the motion is in the vertical direction. Therefore the magnitude of the force in x-direction will be zero:

<u>Fₓ = 0 N</u>

For upward direction the force will be positive:

<u></u>F_y<u> = 9.08 N</u>

<u></u>

(b)

Since the motion is in the vertical direction. Therefore the magnitude of the force in x-direction will be zero:

<u>Fₓ = 0 N</u>

For upward direction the force will be negative:

<u></u>F_y<u> = - 9.08 N</u>

<u></u>

(c)

Since the motion is in the horizontal direction. Therefore the magnitude of the force in y-direction will be zero:

<u></u>F_y<u> = 0 N</u>

<u>Fₓ = 9.08 N</u>

A particle executes simple harmonic motion with an amplitude of 3.00 cm. At what position does its speed equal half of is maximu
Mrac [35]

Answer:

x=±0.026m

Explanation:

In simple harmonic motion the maximum value of the magnitude of velocity

v_{max}=wA=\sqrt{\frac{k}{m} }A

The speed as a function of position for simple harmonic oscillator is given by

v=w\sqrt{A^{2}-x^{2}

where A is amplitude of motion

Given data

Amplitude A=3 cm =0.03 m

v=(1/2)Vmax

To find

We have asked to find position x does its speed equal half of is maximum speed

Solution

The speed of the particle the maximum speed as:

v=\frac{V_{max} }{2}\\ w\sqrt{A^{2}-x^{2}  }=\frac{wA}{2}\\  A^{2}-x^{2}=\frac{A^{2} }{4}\\ x^{2}=A^{2}- \frac{A^{2} }{4}\\ x^{2}=\frac{3A^{2}}{4} \\x=\sqrt{\frac{3A^{2}}{4}}

x=±(√3(0.03)/2)

x=±0.026m
