Red blood cells contain hermoglobin whiles white blood cells do not. Hermoglobin is what gives it its red color.
Answer: Attach it to clothing, personal flotation device or the person's person.
Explanation:
This particular Question or problem has to do with the rules and regulations or laws governing the use of Personal Watercraft(PWC) in the state of Florida in the United States of America. Hence, one of the rules that is applicable to the use of boats and waterways or the use of personal watercraft in Florida is that in florida, if ones pwc is equipped with an engine cut-off lanyard the person operating it must ATTACH IT TO THE CLOTHING, PERSONAL FLOATATION DEVICE IR THE OPERATORS' PERSON.
Another rule band the use of flammable personal flotation device with Personal Watercraft(PWC) in the state of Florida. All this rules and guildlines are made to limit or minimize hazards.
This shifts chemical equilibria toward the products or reactants, which can be determined by studying the reaction and deciding whether it is endothermic or exothermic....
The wavelength of the light ray with the given frequency is 4.05 × 10⁴nm.
Given the data in the question;
- Frequency of the light ray;
- Wavelength;
<h3>Wavelength</h3>
Wavelength can be simply defined as the spatial period of a periodic wave. When the shapes of waves are repeated, the distance over which they are repeated is called wavelength. Wavelength is expressed as;
Where 
is wavelength, f is frequency and c is speed of light( 
)
We substitute our values into the expression above to determine the wavelength of the light ray.
Therefore, the wavelength of the light ray with the given frequency is 4.05 × 10⁴nm.
