Non-crystalline ceramics deform by viscous flow instead of dislocation motion, True

Ceramics are inorganic compounds. They can be non-metallic or solid materials that can be comprised of metals, non-metal or atoms. Ceramics are known are hard and strong in compression but weak in tension and shearing, these materials are also known for their brittle properties.

Ceramics exits in two major types, these are: crystalline ceramics and non-crystalline ceramics. Crystalline ceramics are those that can easily be shaped to situ, formed with powders and sintered to form a solid body.

On the other hand non-crystalline ceramics are more of glass and formed through melting. They have no regular crystalline structure, and also have no slip or dislocations in them

Non-crystalline ceramics when deforming, they allow ions to slide past each other, hence deforms by breaking and reforming bonds. A condition known as viscous flow.

Thus, the statement given is True, option a is correct.

Heat detectors are best used in kitchen.

Heat is also referred to as thermal energy and it can be defined as a form of energy that is transferred from a physical object (body) to another due to a difference in temperature.

During the process of heat conduction, heat is typically transferred between objects that have different degrees of temperature and materials that are directly in contact with each other but differ in their ability to either accept or donate electrons.

Additionally, a heat detector simply refers to a mechanical and electrical device that is designed and developed to detect the quantity of heat that is available in a particular place. Generally speaking, a heat detector is best used in small confined places such as a kitchen.

The graphs indicate that Al 5083 alloy satisfies the required criteria without undergoing any heat treatment. Its strength can be further improved by solid solution heat treatment through the quenching process after heat treatment.

What is alloy?
A chemical element mixture called an alloy must contain at least one metal. The properties of a metal, such as electrical conductivity, ductility, opacity, and lustre, will all be retained in the alloy's final product, unlike chemical compounds with metallic bases, but an alloy may also have additional properties that set it apart from pure metals, such as increased strength or hardness. In some circumstances, an alloy may keep vital qualities while lowering the material's overall cost. In other cases, the combination gives the individual metal components of the mixture synergistic properties like mechanical strength or corrosion resistance.

An alloy can be distinguished by its metallic bonding properties. While atomic fraction is employed in basic science research, the alloy constituents are frequently measured for practical purposes using mass percentage.


Additionally, if aged-hardened, Al7075 alloy has greater strength than Al5083 alloy. Any of the two alloys can be chosen based on their qualities.

The methods used to seismically retrofit a building are: beam addition method, seismic wall addition method, support point adding method, and

seismic isolation method.

In construction of a building, seismically retrofitting or earthquake retrofitting is commonly done. The major reason to why it is done is to prevent displacement from the structure's foundation.

When seismically retrofitting is done, a building is considered safer and less likely to suffer damage when earthquake or any seismic forces strike.

So a retrofit is worth it as it will strengthen a building or an house against shake damage to help people living in it to remain safe and less worried. The following methods can therefore be used to provide a retrofit or to seismically retrofit a building:

Beam addition method

This is done by adding beams between the main girders of the existing reinforced concrete to improve the load carrying capacity of the reinforced concrete.

Seismic wall addition method

This is done by placing new reinforced concrete walls between existing ones and bonding them to improve load carrying capacity as a structural body

Support point adding method

This is done by supporting sections of beams and other existing concrete members with new members to reduce the span of members

Seismic isolation method

This is done by using seismic isolation bearings to reduce the seismic energy applied to the structure. This will improve the building's performance values during an earthquake.

Multiple antennas are utilized at both the source (transmitter) and the destination in wireless communications known as MIMO (multiple input, multiple output) (receiver). By letting data to travel through several signal pathways simultaneously, the antennas at either end of the communications circuit are merged to reduce mistakes, improve data speed, and increase the capacity of radio transmissions.

The data has a greater chance of reaching the receiving antenna unaffected by fading when numerous versions of the same signal are created, which improves the signal-to-noise ratio and error rate.

If six 20 watt, 12 volt luminaires are supplied from a small. The voltage applied to the fixtures is: 8.61 volts.

First step is to find the amperes using this formula

I = P ÷ E

Where:

I =load current (amperes)=?

P =Product of voltage=(6)(20)

E =Electrical circuit's=12

Let plug in the formula

I= (6)(20) ÷ 12

I=120÷12

I= 10 amps

Second step is to determine the Voltage drop using this formula

Vd = [2KIL] ÷ CMA

Where:

Vd = Voltage drop( volts)=?

K= Direct current constant=11.6

I = Load current (amperes)= 10 amps

L = Length in feet=60 feet

CMA = Circular mill area= 4110

Let plug in the formula

Vd = [(2)(11.6)(10)(60)] ÷ 4110

Vd =13,920÷4110

Vd = 3.3869 volts

Third step is to find Voltage at fixture using this formula

Voltage at fixtures=Electrical circuit's-Voltage drop

Voltage at fixtures=12 - 3.3869

Voltage at fixtures=8.6131 volts

Voltage at fixtures=8.61 volts (Approximately)

A force is an effect that can alter an object's motion according to physics. A force can cause an object with mass to accelerate when it changes its velocity, for as when it moves away from rest. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction. It is calculated using the newton SI unit (N). Force is denoted by the letter F. (formerly P).
The net force acting on an object is equal to the rate at which its momentum varies over time, according to Newton's second law in its original formulation.

Stress changes the shape or volume of a rock temporarily and later when stress is removed, the rock returns to its original shape or size. The rock comes under the type of elastic strain. Hence, option (d) ‘elastic strain’ is the correct answer.

Stress causes the build-up of strain, which results in the deformation of rocks. In response to stress, a very small amount of deformation in the shape or volume of the rock occurs temporarily. This is called elastic strain. It is because the resulting deformation of the rock is not permanent; when stress is removed, the rock comes back to its original shape or volume.
