To calculate this we will use the light equation:

λ

We have Frequency

.
We know that speed of light in vacuum is

.
Since a unit of speed of light is m/s, we can change the unit of frequency Hz to 1/s, since Hz means cycles per second (f=1/T).
So:

25% would have tay-sachs disease, 25% normal, 50% carriers
1) they have similar chemical properties.
for example fluorine from the 17th column is a non metal so does all the elements of that group.
2)they have same valence electrons in their outermost shell
example
electronic configuration of
hydrogen 1, lithium 2,1, sodium 2,8,1 and so on.
3) have same valency.
Answer:
Competition is the rivalry between companies selling similar products and services with the goal of achieving revenue, profit, and market share growth. Market competition motivates companies to increase sales volume by utilizing the four components of the marketing mix, also referred to as the four P's.
