Newly created features always add to the end of the Feature list

Answers

True, Newly created features always add to the end of the Feature list

Feature lists are the blueprint of your website or app, entailing everything the medium must be able to do.

To build a feature list, project teams need to perform feature prioritization, the process of organizing a platform's functionalities by importance.

What is a product feature list?

Product features are a product's discrete areas of new and heightened functionality that deliver value to your customers. You can think of these as little gifts. Broadly, features can refer to goods, components, user interface (UI) design, and arrangement upgrades.

What do you mean by features?

A component is a distinctive trait or a special attraction. Feature can also mean to give special awareness to something.

The word feature has several other senses as a noun and a verb. A feature is a unique marker or characteristic that something has.

Resistance to impact is an example of a(n)•obtuse property
•thermal property.
•mechanical property.
•general physical property.

Answers

Answer:

Mechanical property

Explanation:

MECHANICAL PROPERTIES can be defined as the ability of a metal or material to remain undamaged after different type of forces has been applied or used on them because forces or loads are often applied to metal, material or physical properties which is why MECHANICAL PROPERTIES enables us to know the strength , toughness as well as the hardness of metal and the way this metal perform or react when different forces are applied on them.

Lastly any metal, material or physical properties that has the strength , hardness and resistance to withstand or remain unaffected despite the loads or forces use on them is an example of MECHANICAL PROPERTIES.

Therefore Resistance to impact is an example of a(n) MECHANICAL PROPERTIES.

Final answer:

Resistance to impact refers to the mechanical property of a material. This property is observed when materials can resist damage under sudden or high force, such as a rubber ball deforming and then restoring its original shape.

Explanation:

Resistance to impact is an example of a mechanical property. Mechanical properties refer to the behavior of materials when subjected to mechanical forces such as impact, tension, compression or shear. For example, a rubber ball resists impact because it deforms and then returns to its original shape, absorbing the energy of the impact. Materials with good resistance to impact don't damage easily when subjected to sudden or high force.

If you detect that something’s wrong while lowering a lift, you should try to get the vehicle down as fast as possible

Answers

Trying to get the vehicle down as fast as possible is an unsafe practice when you detect that something is wrong while lowering a lift

When lifting or lowering a load ( car ) there safety tips that should be adhered to to ensure proper and safe lifting and lowering of the load and some of these tips are :

  • Ensure the lifting angle is right
  • Ensure that the lifting springs are not in contact with sharp edges
  • Also ensure all personnel are in the right position to avoid/reduce hazards

Therefore when you notice that there is something wrong when trying to lower a load it is best to come down and allow a qualified mechanic to check what is wrong with the lift and also fix it before you can resume lowering.

Hence we can conclude that it is not a safe practice to try to lower the vehicle as fast as possible when there is something wrong while lowering.

False, it depends on the situation. If the lift is tilting or anything like I would then get down. Certain training will say to get out and see if you can keep lowering,
