We will apply the concept of period in a pendulum, defined as the product between 2
by the square root of the length over gravity, this is mathematically
Here,
T = Period
L = Length
g = Acceleration due to gravity
For the period to be 1 second, then we must look for the necessary length for such a requirement so
The meter's length would be slight less than one-fourth of its current length. Also, the number of significant digits depends only on how precisely we know g, because the time has been defined to be exactly 1s.
Therefore the correct answer is C.
Option B i.e discretion is the right and correct answer.
[C]utting programs that were not effective or essential and even some that were, but are now unaffordable; and precisely targeting our investments. Every department will feel the impact of these reductions as they cut programs or tighten their belts to free up more resources for areas critical to economic growth.

2012 Budget Message of the President.
The President above clearly refers to the Discretion Spending where portion of the budget is decided by Congress through the annual appropriations.
D.) Because it has a definite composition...
Answer:
A. Create habitats for coral, but not fish
It would be D. Anthony has more power than Angel. They both do the same amount of work, because it is the same weight over the same distance. Power is calculated by dividing work by time. Since the amount of work they did is the same but Anthony did that amount of work in less time, he would have more power.
