Describe why chemical bonding occurs. Give two examples of how<br> bonds can form.
Vladimir [108]

Explanation:

Chemical bonding results from attractive forces that joins chemical species.

  • Noble gases show no tendency to combine with themselves or with other kinds of atoms because of their completely filled outer energy levels.
  • The driving force for most interatomic bonding is the tendency to have completely filled outer energy levels just like the inert gases.
  • The stable configuration can be attained by losing or gaining of electrons or sharing of pairs of electrons.

Two examples of how bonds form:

Bonds can be formed by:

  1. Losing and gaining of electrons to form electrovalent or ionic bonds.
  2. Sharing of electrons to form covalent bonds.

Sinusoidal waves 5.00 cm in amplitude are to be transmitted along a string that has a linear mass density of 4.00× 10⁻²kg /m . T
mylen [45]

The highest frequency (f) at which the source can operate is given as:

f = 55.133Hz.

<h3>What are sinusoidal waves?</h3>

The most realistic representation of how many objects in nature change state is a sine wave or sinusoidal wave.

A sine wave depicts how the intensity of a variable varies over time.

<h3>What is the calculation justifying the above result?</h3>

P = (1/2) μω²A²v

300W = 1/2 (4 X 10⁻²kg/m) ω₂ (0.05m)²v

Thus the wave speed is:

v = √(T/μ)

= √[(100N)/(4 X 10⁻²kg/m)

= 50m/s

300W = 1/2(4 X 10⁻²kg/m) ω²(0.05m)² (50m/s)

⇒ ω = 346.41 1/s

ω = 346.41 1/s

= 2πf

⇒ f = 55.133Hz

What is the scientific saying/principle that explains why a hammer and a screwdriver, both made of steel, are used for different
deff fn [24]

Hammer and screwdriver perform different tasks because they are both simple machines.

A machine is simply a device that can be used to perform a task. This  machine can be any physical system or device designed to perform a specific task.

The efficiency of the machine describes the easy with which each machine or tool is able to use input power to overcome a task.

Machines are designed to overcome a particular task with little effort in order to increase its efficiency.

Hammer and screwdriver, are both examples of simple machines.

Thus, Hammer and screwdriver perform different tasks because they are both simple machines.
