Answer:

 t  = 16.5s

Explanation:

Given parameters:

Acceleration = 3.1m/s²

Initial velocity  = 0m/s

Final velocity  = 51m/s

Unknown:

Time taken  = ?

Solution:

To solve this problem we need to reiterate that acceleration is the rate of change of velocity with time.

So;

        Acceleration  = \frac{v  - u }{t}  

v is the final velocity

u is the initial velocity

t is the time taken

  So;

       3.1  = \frac{51 - 0}{t}  

    3.1t  = 51

       t  = 16.5s

Who said Freedom is the oxygen of the soul?
____ [38]

Moshe Dayan said that the Freedom is the oxygen of the soul.

Oxygen is a plentiful and highly reactive element on the earth. Oxygen comprises about 21% of the earth's atmosphere. In its elemental form oxygen is a gas and diatomic.

The earth's crust contains a large amount of oxygen as well, primarily in the form of silicates. Many metals react with oxygen to form oxides. For example, copper reacts with oxygen to form copper (II) oxide. Iron reacts with oxygen to form iron(III) oxide (rust). Magnesium also reacts with oxygen, forming magnesium oxide.

Metalloids will also react with oxygen. Upon reaction with oxygen silicon forms silicon dioxide, the main component of sand.

Acid-base indicators are compounds that can measure the level of acidity for solutions. For example, phenolphthalein is a compound that is colorless in acidic solutions and pink in basic solutions.
