Answer:
<em>The hang time is 2.04 seconds</em>
Explanation:
<u>2-D Motion
</u>
It referred to as a situation where an object is launched in such a way it describes a curve, reaches a top height and then returns to ground level after traveling a certain distance x away from the launch point.
Let be the launching speed forming an angle with the horizontal reference. The hang time (time the object remains in the air) is given by
Since
Then
We'll use the given values
The hang time is 2.04 seconds
Answer:
Solution:
As per the question:
Area of the plates is given by 'A'
Separation distance between the plates is 'd'
Now, after insertion of the metal plate with same area 'A' and thickness, a < d
in between the plates, the capacitance of the capacitor changes.
The capacitance of the air capacitor (parallel plate) is generally given by:
where
C = Capacitor's capacitance
= Permittivity of the free space
Now, when the metal slab is inserted the distance is reduced to (d - a)
Thus
The best way would be to test groups of each kind of fabric by exposing them to the same amount of water for the same amount of time. The correct option is A.
<h3>Scientific experiments</h3>
In conducting scientific experiments to compare test subjects such as the fabrics mentioned in the illustration, the test subjects must be subjected to the same conditions.
The outcome of the experiment will no longer be scientifically valid if the test subjects are not exposed to the same condition.
Thus, the two fabrics must be exposed to the same amount of water for the same amount of time in order to come to a valid conclusion about which is a better water repeller among the two.

Objectivity refers to the ability of a writer to present ideas or situations factually as they are without partiality.
<h3>What is objectivity in writing?</h3>
Objectivity refers to the ability of a writer to present ideas or situations factually as they are and not based on his or her own preconceived notions or bias.
To check for objectivity in a web document, one has to ;
- check the source of the material
- compare different web documents with it
- check on the websites credibility rating from others
Therefore, objectivity means being truthful and impartial.

Answer:
The answer to the question is 72N
The formular for calculating force is;
Force = Mass× acceleration due to gravity
therefore 6kg×12m/s/s = 72N
