calculating kinetic energy 1200kg car moving at 10​

Answers

Answer 1

Answer:

60000J

Explanation:

Given parameters:

Mass of car  = 1200kg

Speed  = 10m/s

Unknown:

Kinetic energy  = ?

Solution:

The kinetic energy is given as:

   Kinetic energy  = [tex]\frac{1}{2}[/tex]  m v²  

Now insert the parameters and solve;

   m is the mass

    v is the velocity  

 Kinetic energy  =  [tex]\frac{1}{2}[/tex] x 1200 x 10²   = 60000J

Answers

Answer:

A endocytosis

Explanation:

The process by which a cell takes in a large particle is called endocytosis. Therefore, the correct option is option A.

What is endocytosis?

Endocytosis is the procedure by which molecules are actively transported into the cell by being engulfed by its membrane. All cells use endocytosis and exocytosis to transport substances that cannot passively cross the membrane. Exocytosis serves the opposite purpose by ejecting molecules from the cell.

The requirement for homeostasis ensures an equal flow all molecules into and out of a cell, like all of the body's systems. This indicates that the number of molecules exocytosis and endocytosis both equal the number of molecules into the cell. The two systems work together to maintain a balance between nutrients and waste that is necessary for normal cell growth and function. The process by which a cell takes in a large particle is called endocytosis.

Therefore, the correct option is option A.
