Answer:
I only know answer A and it's 2825.28 N/m, with rounding it's 2825.5
Explanation:
Use the m*g*h=1/2*k*x^2 equation
96*9.81*60=1/2*k*2^2
5650.56=2k
5650.56/2=2825.28N/m
An analogy to explain this phenomena is the traffic explanation: Imagine you are in rush hour of traffic in a major city. Now imagine that all the traffic is only on one lane instead of being spread out on all six lanes. With more paths, there is less resistance to flow.
Your answer is: Imagine you are in rush hour of traffic in a major city. Now imagine that all the traffic is only on one land instead of being spread out on all six lanes. With more paths, there is less resistance to flow.
Have an amazing day mate!

Answer:
C) high efficiency light bulbs, because they produce more heat
The work of Brian mind interface is to learn that’s my guess lol
Consider the formula ...
Current = (voltage) / (resistance) .
If the resistance doesn't change, then the current is
directly proportional to the voltage.
If the voltage decreases to 1/3 of what it used to be,
then the current does the same thing.
1.2 A ----> 0.4 A
