If the half life of a radioactive isotope is 1 day, then how much of the original isotope remains at the end of two days?

ikadub [295]

$\huge{\color{magenta}{\fcolorbox{magenta}{black}{\huge{\color{white}{\fcolorbox{aqua}{black}{✿ᴀɴsᴡᴇʀ✿}}}}}}$

25%

Explanation:

In a half life of a radioactive isotope is 1 day,it means it loses its half mass each day

We a formula for N half life

$\sf { \frac{1}{2} }^{n}$

where n is the number of days

Here the isotope is kept for 2 days

so it's left over mass will be

$\sf { (\frac{1}{2}) }^{2} \\ \\ \\ \frac{1}{2} \times \frac{1}{2} \\ \\ \sf \frac{1}{4}$

It's left over mass 1/4th of the original mass

Now, we need to find it's percentage by multiplying with 100

$\sf \frac{1}{4} \times 100 \%\\ \\ \sf \cancel\frac{100}{4} \% \\ \\ \sf 25\%$

So 25% mass will be left after 2 day of half life radioactive isotope.

snow_tiger [21]

Answer:

B. Pluto's orbit is not clear of other objects

Explanation:

Pluto is a dwarf planet and considered as ninth planet of the solar system.

A large body whose orbit do not clear the neighbourhood is classified as a dwarf planet. The gravity of Neptune limit the orbit of Pluto and shares its orbital neighbourhood with many Kuiper belt objects.

Hence, the correct answer is "B. Pluto's orbit is not clear of other objects".
