Answer:
Birds in different areas were exposed to different food sources.
Explanation:Im almost 100 percent this is it.
Answer:
Explanation:
Let the potential difference remains same. So, by insertion the dielectric, the capacitance
C' = KCo
As V remain same, so Q' = KQo
Energy, U' = 1/2 C'V² = KCo
Electric field, E' = E/ K
Where, k be the dielectric constant.
Thus, V remains same
Energy increases
C increases
E decreases
Q increases.
Answer:
0.0786
Explanation:
zero after the decimal place is not a significant figure since it comes before the real integer "7".
"5 " in ten thousandth place is rounded off to "6" because the next digit is also another "5",
so we get the three sfg 0.0786
The answer for this question would be choice "<span>B. The average annual dose of background radiation is 250 times smaller than the dose linked to increased cancer risk."
You only have to compare 4.0 x 10^-4 and 1.0 x 10^-1. And if you can observe carefully, when you try to multiply the average annual dose of background radiation by 250, you would get 0.1 which is equivalent to the amount of annual dose linked to increased cancer risk. Therefore, the answer is B.</span>
