color of the indicator in asolution of ph 3 will be yellow.
To neutralize gastric juices in your stomach antacids contain basic
chemicals. The acid in your stomach has a lower pH value. To neutralize this
and reach a pH of 7, the antacid must contain a base.
Answer:
You drop a rock from rest out of a window on the top floor of a building, 30.0 m above the ground. When the rock has fallen 3.00 m, your friend throws a second rock straight down from the same window. You notice that both rocks reach the ground at the exact same time. What was the initial velocity of the ...... rest out of a window on the top floor of a building, 30.0m above the ground. ... You Notice That Both Rocks Reach The Ground At The Exact Same Time. ... You drop a rock from rest out of a window on the top floor of a building, 30.0m ... When the rock has fallen 3.20 m, your friend throws a second rock straight down from ...
Explanation:
Given that,
Mass of the block, m = 12.2 kg
Initial velocity of the block, u = 6.65 m/s
The coefficient of kinetic friction, 
(a)The force of kinetic friction is given by :

mg is the normal force
So,

(b) Net force acting on the block in the horizontal direction,
f = ma
a is the acceleration of the block

(c) Let d is the distance covered by the block before coming to the rest. Using third equation of motion as follows :

Hence, this is the required solution.
