Given :
- In a neutral atom that has an atomic mass of 22 and atomic number of 12.
To Find :-
Solution :-
<u>As </u><u>we</u><u> know</u><u> that</u><u>,</u>
- n(neutrons) + n(protons) = A
- n(neutrons) + 12 = 2 2
- n(neutrons) = 22-12
- n(neutrons) = 10
<u>Hence </u><u>the</u><u> </u><u>required</u><u> answer</u><u> </u><u>is </u><u>1</u><u>0</u><u>.</u>
Idk
The answer and I can’t see it
Answer:
160 cubic centimeters
Step-by-step explanation:
step 1
Find the scale factor
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
Let
z ---> the scale factor
----> the ratio of corresponding radii
simplify
step 2
Find the volume of the smaller cone
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z ---> the scale factor
x ----> the volume of the smaller cone
y ---> the volume of the larger cone
we have
substitute
40 + 0.20m = 25 + 0.35m
40 - 25 = 0.35m - 0.20m
15 = 0.15m
15 / 0.15 = m
100 = m.....they will be the same at 100 miles
