Each station can detect how far away the epicenter was. So each station basically has a circle made of possible epicenters. When you have three, you narrow it down to one, final point.

Answer:
How much electricity the appliance can hold, the number of hours the appliance is used in a day, and how many days it is used of the year.
Explanation:
Once we find all these things its simple math to figure out how many watts the appliance uses.
Answer:
d = 61.75 m
Explanation:
Given that,
A ball droped from a building.
We need to find how fast is it traveling after falling 3.55 s.
As it is dropped, its initial velocity is equal to 0.
Let d is the distance it covers after falling 3.55 s.
We can use second equation of motion to find d.

Here, u = 0 and a =g

So, it will cover 61.75 m after falling 3.55 seconds.
