Answer:
The necessary separation between the two parallel plates is 0.104 mm
Explanation:
Given;
length of each side of the square plate, L = 6.5 cm = 0.065 m
charge on each plate, Q = 12.5 nC
potential difference across the plates, V = 34.8 V
Potential difference across parallel plates is given as;
Where;
d is the separation or distance between the two parallel plates;
Therefore, the necessary separation between the two parallel plates is 0.104 mm
Let us divide this problem into two parts:
1) Sam rides up the mountain.
2) Sam rides down the mountain.
1.
Since speed is distance over time, as:
Therefore, distance would be:
Where s = distance,
v = speed,
t = time.
In the problem, Sam's speed while riding up is v = 6 miles/hour = (6 * 1609.34 / 60) = 160.934 meters/second(in SI Units). Plug this value in the above equation, you would get:
--- (A)
2.
As Sam rides down the mountain, the speed given is:
Convert it in SI units; the speed would be in SI unit:
v = 54 miles/hour = (54 * 1609.34 / 60) = 1448.406 meters/second(in SI Units). Plug this value in the distance equation, you would get:
Since the
, therefore,
=>
Now the condition is that the whole trip, up and down, takes 40 minutes(2400seconds), it means:
Plug in the value of
in the above equation, you would get:
Therefore,
meters (in relation to seconds)
meters (in relation to hours)
Now the last step is to convert meters into miles, you would get:
So the answer is 3.6miles.
