The first one would be frequency. Here’s what I found to support that “The number of waves passing a fixed point in a certain amount of time is called the The word frequent means “often,” so frequency measures how often a wave occurs. Frequency is often measured by counting the number of crests or troughs that pass by a given point in one second”
The second one would be a medium “Mechanical waves require a medium in order to transport their energy from one location to another. “
I think it's the last one
Answer:
The voltage is 
Explanation:
From the question we are told that
The voltage of the battery is 
The capacitance of the capacitor is 
The resistance of the resistor is 
The time taken is 
Generally the voltage of a charging charging capacitor after time t is mathematically represented as
Here 
is the voltage of the capacitor when it is fully charged which in the case of this question is equivalent to the voltage of the battery so
Answer:
The answer is A because it is a resource that takes many many years to make more of and we cannot make it ourselves
