Answer:
15.64m/s
Explanation:
This is a unit of speed which is the rate of change of distance with time
I am driving at 35mph: and I want to express as m/s
mph means miles per hour
This suggests that I have to convert miles to m and hrs to secs:
for distance 1.609km = 1mi
1000m = 1km
for time:
1hr = 60minutes
1min = 60seconds
Using dimensional analysis:
x 
x 
x 
x 
= 15.64m/s
An indicator is a substance that undergoes a distinct noticeable change when conditions in its solution change. A dye in chemistry <span>is a colored substance that has an affinity to the substrate to which it is being applied.</span>
The atoms of element
differ from each other based on the number of protons or electrons they have.
The number of protons or electrons is called the atomic number of an element
which serves as its original identity.
<span>Now, an isotope of an
element differs in their number of neutrons but the number of protons or
electrons are similar.</span>
