Answer:

C. Downhill slope

Explanation:

Scanning's a good driving technique that prevents us from having a traffic accident. In order to be alert of what's happening and could possibly happen, a driver must always pay attention to his/her sorroundings by using the mirrors of the vehicle, looking a long distance ahead, checking the sides of the road for any unforeseen event and keeping the blind spot in mind. In the example, the only factor that doesn't test the driver's attention is a downhill slope.

The half-life of carbon-14 is about 5700 years. If you left those 100 carbon-14 atoms to sit around for 5700 years, how many wou

Sergeu [11.5K]

Answer:

50 atoms have decayed during that time

Explanation:

The radioactive decay is represented as

$N = N_0 * \frac{1}{2}^X\\$

Where N is the amount of radioactive element after a certain time period

N0 is the amount of radioactive element during the initial time period

X is the half life of the radioactive element

Substituting the given values in above equation, we get:

$N = 100 * \frac{1}{2}^1\\N = 50$ atoms

So, 50 atoms of carbon-14 remain are left after decaying for 5700 years.

Hence, atoms of carbon-14 that decay during 5700 years are 100-50 - 50
