Answer:

The right choice is "wind power requires a lot of space and depends on local weather patterns "

Explanation:

  1. solar power produces harmful chemicals
  • it is incorrect because solar power doesn't produce any chemicals

    2. geothermal power requires more land than other power plants  

  •   it is incorrect because geothermal power requires digging a stable 5 km-deep shaft not a land

germanium -66 has a half-life of 2.5 hours. you have 35 grams of radioactive material. after 16 days, how much radioactive mater
Maru [420]

Hey there!

A half-life means after a certain amount of time, half of that substance will be gone/changed after that time.

How many half-lives are in 16 days?

Multiply 16 by 24 (to get the total hours) and divide that by 2.5.

That is 153.6 half-lives.

35(0.5)^(153.6) represents the equation for this.

Simplify this and get 8.88 x 10^(-45).

There will be 2.02 x 10^(-45)g of germanium-66 sample remaining after 16 days.

Hope this helps!
