Answer:
The time it'd take for the element to have 15 g of mass is approximately 68 min.
Step-by-step explanation:
The radioactive decay of a substance is given by the following formula:
Since the element has a half life of 12 minutes, this means that after this time the mass of the element will be half of it was originally, therefore:
Therefore the mass of the element is given by:
If the initial mass is 760 g and the final mass is 15 g, we have:
The time it'd take for the element to have 15 g of mass is approximately 68 min.Step-by-step explanation:
Answer:
a) input 9,10,11
output 12,13,14
Step-by-step explanation:
If we look at the pattern, number 3 is added to the consecutive input numbers 1, 2 and 3 to generate a set of output numbers.
Clearly, option (a) follows this rule. Number 3 is added to the consecutive input numbers 9, 10 and 11 to produce 12, 13 and 14.
In option (b), 4 is added to the input numbers.
In option (c), 2 is added to the input numbers and
in option (d), 3 is multiplied to the input numbers.
Hence, the correct option is (a).
