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:
c. both have same energy
Explanation:
The complete question is
suppose you have two cans, one with milk, and the other with refried beans. The cans have essentially the same size, shape, and mass. If you release both cans at the same time, on a downhill ramp, which can has more energy at the bottom of the ramp? ignore friction and air resistance..
a. can with beans
b. can with milk
c. both have same energy
please explain your answer
Since both cans have the same size, shape, and mass, and they are released at the same height above the ramp, they'll possess the same amount of mechanical energy. This is because their mechanical energy, which is the combination of their potential and kinetic energy are both dependent on their mass. Also, having the same physical quantities like their size and shape means that they will experience the same environmental or physical factors, which will be balanced for both.
The answer is d hope this helps
