1.8 x 10⁻⁵J
<h2>
Explanation:</h2>
The energy (E) stored in a capacitor of capacitance, C, when a voltage, V, is supplied is given by;
E = 
x C x V² -------------------(i)
Now, from the question;
C = 2.00μF = 2.00 x 10⁻⁶F
V = 18.0V
Substitute these values into equation (i) as follows;
E = x 2.00 x 10⁻⁶ x 18.0
E = 1.8 x 10⁻⁵J
Therefore, the quantity of energy stored in the capacitor is 1.8 x 10⁻⁵J
On the dog's return trip (between <em>t</em> = 10 and <em>t</em> = 12.5 seconds), the slope of the position function is steeper than during the first 5 seconds, which means the dog ran home faster. The only option that captures this is D.
You can check to make sure that the dog indeed runs twice as fast on the return trip. The slope of the position function during the first 5 seconds is
(change in position) / (change in time) = (5 - 0) / (5 - 0) = 5/5 = 1
while during the return trip, it is
(0 - 5) / (12.5 - 10) = -5/2.5 = -2
Ignoring the sign (which only indicates the direction in which the dog was running), we see that the dog's speed on the return trip was indeed twice as high as during the first 5 s.
Answer:
(a) Moon has smaller diameter and lower density than earth
Explanation:
Moon has smaller diameter than earth earth has a diameter of 12742 km whereas moon has a diameter of 3474.21 km
So for density density is given by 
From the relation we can see that density is dependent on mass and volume directly proportional to mass and inversely proportional to diameter
But in case of earth and moon mass is more dominating than volume so density is less for moon than earth
