Answer:
Ratio of parent to daughter nuclei is 16 : 1
OR
1 : 0.0625
Explanation:
The half of a radioisotope is the time it will take half of the original mass to decay.
Let the original mass be y
After the first half life, the new mass will be y/2
After the second half decay, the new mass will be y/4
After the third half decay, the new mass will be y/8
After the fourth half life decay, the new mass will be y/16.
Thus the ratio of the mother nucleus to the daughter nucleus will be y : y/16
Multiply the ratio through by 16
= 16y : y
= 16 : 1
Answer:
I = 4.28 [amp]
Explanation:
To solve this type of problems we must have knowledge of the law of ohm, which tells us that the voltage is equal to the product of resistance by current.
Initial data:
v = 1.5 [volt]
R = 0.35 [ohms]
v = I * R
therefore:
I = 1.5 / 0.35
I = 4.28 [amp]
Using V= vo +at with Vo = 0 and a= 4m/sec2.
V= 0+ 4x8= 32m/s
