2. Answer in brief: 2.1 What is the SI unit of force ? 2.2 How does the pressure change as one goes deeper in water ? 2.3 Where do you find immovable bone-joint in human body?
Answers
Answer:
2.1 -The SI unit of force is the newton, symbol N.
Explanation:
. The base units relevant to force are: The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg.
2.2-pressure increases with ocean depth.Beacuase the fluids in your body are pushing outward with the same force.the deeper you go under the sea,the greater the pressure of the water pushing down on you.For every 33feet (10.06meters) you go down,the pressure increases by one atmosphere.
2.3-An immovable joint connects the ends of the bones by a tough fibrous tissue. Examples of immovable joints are sutures found between the bones of the skull, syndesmosis between long bones of the body, and gomphosis between the root of a tooth and the sockets in the maxilla or mandible.
is it okay.if it is okay mark me as a brainlist
Answer:
2. 1) The SI unit of force is Newton (N) .
2.2) Pressure increases with ocean depth. We don't feel it because the fluids in our body are pushing outward with the same force . The deeper we go under the sea, the greater the pressure of the water pushing down on you . For every 33 feet ( 10.06 metres) you go down , the pressure increases by one atmosphere.
2.3) hand, leg etc
