<span>1.6625 x 10−21</span>
<span>mass of one helium atom x 250 </span>
Express 250 as 2.50.
(6.65 x 10−24)(2.50 x 102)
16.625 x 10<span>−22</span>
The answer is - a.error caused by selecting a bad sample
T is equal in both situations ... d = r X t so d/r = t
c is rate of waters current
14(12 - c) = 7(12 + c)
2(12 - c) = 12 + c
24 - 2c = 12 + c
12 = 3c
4 = c The rate of the waters current is 4 miles per hour.
Answer:
no solutions
Step-by-step explanation:
n+(-n) = 3+ 15
n+-n = 0
0= 18
False
There are no solutions
