Convert the scientific notation to a decimal number. Type the correct answer in the box. 4 × 10-5 cm = cm
MakcuM [25]

Answer:

4 * 10^{-5}cm = 0.00004cm

Explanation:

Given

4 * 10^{-5}cm = [\ ]cm

Required

Solve

Apply law of indices

4 * \frac{1}{10^5}cm = [\ ]cm

Evaluate 10^5

4 * \frac{1}{100000}cm = [\ ]cm

4 * 0.00001cm = [\ ]cm

0.00004cm = [\ ]cm

Hence:

4 * 10^{-5}cm = 0.00004cm

The question is below!
Agata [3.3K]
The anode is the negative electrode and so will be donating electrons to assist in this chemical reaction occuring. All reactions accept electrons as reactants. The key issue is the reduction potential Eo (+1.8V). This is greatest for the reaction:

Co3+ + e -> Co2+

Therefore this reaction has the greatest tendency to occur.

How is bacteria on mars counted as life but a heartbeat on earth not?
Sever21 [200]

Answer:

It is considered life, but that doesn’t have to do much with abortion.

We kill things all the time. Unless you are vegetarian, lots of animals are killed to give you meat. Even if you are, you’ll probably swat a mosquito that’s trying to bite you. And what about the bacteria inside your body that are constantly killed to keep you healthy?

The question is how much this life is worth. This becomes more a question of ethics, but I think we can all agree a human life is worth a lot. So killing humans is wrong. What about somewhat intelligent animals? Well, killing them just for the fun of it or because you can is wrong as well I think.Most people think that’s okay, although some people will disagree and become vegetarians.

Insect life is worth less, and killing an insect is seen by most people as okay as long as you have even a small reason for it (like being irritated by a buzzing fly).

And all the way on the bottom are bacteria. They are not conscious, even though alive.

Sorry about the first answer. I didn't look at the question carefully since I wasn't wearing my glasses.

If this doesn't help than I'm sorry.
