Answer:
0.2Hz
Explanation:
The wavelength of a radiowave can be calculated this;
λ = v/f
Where;
λ = Wavelength (m)
v = speed (m/s)
f = frequency (Hz)
Based on the information provided in this question, λ = 1.5 x 10^9 meters, c = 3 × 10^8m/s, f = ?
Hence, using λ = v/f
f = v/λ
f = 3 × 10^8 ÷ 1.5 x 10^9
f = 2 × 10^(8-9)
f = 2 × 10^-1
f = 0.2Hz
An endocrine disruptor is an exogenous substance or mixture that alters the function of the endocrine system and consequently causes adverse health effects in an organism. Lipophilic chemicals are those that do not dissolve in water and have the ability to dissolve in non -polar substances and they have been linked to cause numerous diseases in humans.

Answer:
182,500 units.
Explanation:
<em>The answer would be </em><em>182,500 units of mercury.</em>
<u>Assuming there is an average of 365 days in a years, 10 years is therefore equal to:</u>
10 x 365 = 3650 days.
<u>The stingray eats 50 clams per day. Hence, the total number of clams that would have been eaten in 10 years equals:</u>
3650 x 50 = 182,500 clams
<u>Each clam accumulated 1 unit of mercury in its body from the water it lives in and there is no loss of mercury between the clam and the stingray. Hence, the total number of units of mercury the stingray would have accumulated in 10 years equals:</u>
182,500 clams x 1 unit = 182,500 units of mercury.
