Answer:
The height is 80 meters.
Explanation:
The equation for the distance in the second segment of the fall is as below. In it, we use the initial velocity v1 that the ball had after completing the first segment. From this equation, v1 can be determined:
Next, we use the kinematic equation for velocity at the end of the first segment of a free fall, to determine h1:
The total height is then
Explanation:
When a substance or chemical specie accepts a proton then an acid is formed. Whereas is a substance or chemical specie tends to lose a proton then a base is formed.
Chemical formula of amino group is and it is able to lose a proton to form R-NH-R'. When it tends to gain a proton the it form R-NH_{3} compound.
Chemical formula of carboxylic group is -COOH. When it loses a proton it forms ion and whenit gains an electron then it forms
.
Therefore, we can conclude that the amino and carboxyl functional groups tend to form bases and acids by attracting or dropping a proton.
