Answer:
The two factors are:
• The kind/type of surface involved.
• The force that the surface are being pushed together.
Explanation:
Friction can be said to be the general term used to describe the force that one surface exert on another when they rub against each other.
When the surface is partially not smooth or totally rough, a greater force is been needed to move one surface past the other.
The weight of the can also significantly be a key factor. This is where the need to friction reduction come to play a role; and need for friction reducers like lubricant, rollers etc helps.
Answer:
Option C
Explanation:
Option
A. 6440 mL/min
B. 4340 mL
C. 3500 mL/min
D. 2940 mL/min
Solution
It is required to find the minute ventilation which is equal to the product of rate of breathing and the total amount of gas being inhaled or exhaled per breathe. Let this minute ventilation be denoted by "
"
Thus,
where TD is the tidal volume and Br is the rate of breathing
Substituting the given values we get
We will now reduce the air held in the conducting zone of respiratory system
Air held per breathe 
Total Air held
Amount of fresh air one can breathe in and out every minute
Hence, Option C is correct

When the ocean produces oxygen through the plants (phytoplankton, kelp, and algal plankton) that live in it. These plants then produce oxygen as a byproduct of photosynthesis, which is a process that converts carbon dioxide and sunlight into sugars that the organisms can use for energy then and later on.
Explanation:
Answer:
After the aphotic zone, there's complete darkness. From 1,000 meters below the surface, all the way to the sea floor, no sunlight penetrates the darkness
Explanation:; and because photosynthesis can't take place, there are no plants, either.
