Answer: A=12
Explanation:
4.5
The amount of chemical remaining after twelve seconds in the first reaction is:
A = 12 - 0.5(12)
= 12 - (6)
= 6
In the dissolved reaction, the amount of chemical loses half of itself every four seconds. This is the same thing as dividing by 2 every four seconds.
This is an exponential decay, so the amount of chemical divides by 4 every eight seconds, and by 8 seconds every twelve seconds. The amount remaining after twelve seconds in the second reaction is:
A' = 12/8
= 3/2
= 1.5
The difference between the amounts of chemical remaining is:
6 - 1.5 = 4.5
Therefore, A is 4.5 g greater than A' after twelve seconds.
Answer:
A team's performance is merely the summation of its individual members' abilities.
Explanation:
Working in teams increases collaboration and allows brainstorming. As a result, more ideas are developed and productivity improves. Two or more people are always better than one for solving problems, finishing off difficult tasks and increasing creativity.Performance is merely the summation of each group member's individual contribution.The collective efforts of the members results in a level of performance greater than the sum of the individual parts .
