Answer:
A. Manufacturers rating capacity ↔ 3. Must be marked on all jacks; must not be exceeded
B. Block Used to lift and hold heavy loads, allow them for travel ↔ 1. Place the jack head against this
C. Level surface ↔ 4. Place this under the base of the jack when it's necessary to provide a firm foundation
D. Jack ↔ 2. Used to lift and hold heavy loads, allow them for travel
Explanation:
The manufacturers rating for a jack is labelled on all jacks and should be referenced to compare with the load to be lifted so as to ensure a safe and successful lifting.
In order to lift a load, such as a car, it is required to place the jack on a level surface to provide balance during the lifting task
The head of the jack is placed against the block for lifting heavy objects for proper performance
Answer:
Macronutrients are simply nutrients the body needs in a very high amount e.g Carbohydrate.
MicroNutrients are simply nutrients the body needs but in little amount e.g Minerals.
Explanation:
So for further breakdown:
What are nutrients? Nutrients are essential elements that nourish the body in different capacities. We as humans get most of out nutrients from the food and water we ingest.
Now about Macro Nutrients: From the prefix "Macro" which means large, we can infer that macro nutrients are elements need by the body for the fundamental processes of the body, deficiency in this nutrients are very easy to spot. Examples are: Carbohydrates, Protein, Fats amd Water.
Micro Nutrients: In relation to macro nutrients this are elements that the body needs but are not needed in Large quantities. They mostly work like supporting nutrients. Most chemical activities like reaction that occur in the body are a function of micro nutrients. Defiencies in micrp nutrients may take some time to spot e.g Minerals and Vitamins
In regards to exercise: Macro nutrients are the essential ones here since they are the ones that generate energy. PS: micro nutrients dont generate energy.
In regards to rest: Both the Macro and Micro Nutrients are essentail for the overall well being of the body.
Answer:You are correct, no need to change.

Answer:
Circuit attached with explanation
Explanation:
Hi Dear,
A circuit is attached for your reference.
When you press "start" PB, the supply reaches the motor starter relay coil "M" that is also in parallel with the "start" PB which allows the motor to remain ON even when you release "start" PB as supply to relay coil is directly from supply "L" through "M".
To stop motor just press "stop" PB and the circuit breaks which de-energize the relay coil and the motor stops.
Hope this finds easy to you.
