Answer:
The final energy will be halved of the original energy.
Explanation:
As we know that the capacitance,
C = εA/d
C = capacitance
A = area of plate
d = distance or separation between the plates
ε = permitivity of dielectric material
As you can see from the formula that the capacitance ( ability of the capacitor to store charge) is inversaly proportional to the separation of the plates. If all the other factors kept constant then increasing the distance between the plates will decrease the ability of the capacitor to store energy. So we can say that by doubling the separation, the capacitance or energy stored will become half.

Answer:
θ = 12.60°
Explanation:
In order to calculate the angle below the horizontal for the velocity of the hockey puck, you need to calculate both x and y component of the velocity of the puck, and also you need to use the following formula:
(1)
θ: angle below he horizontal
vy: y component of the velocity just after the puck hits the ground
vx: x component of the velocity
The x component of the velocity is constant in the complete trajectory and is calculated by using the following formula:

vo: initial velocity = 28.0 m/s
The y component is calculated with the following equation:
(2)
voy: vertical component of the initial velocity = 0m/s
g: gravitational acceleration = 9.8 m/s^2
y: height
You solve the equation (2) for vy and replace the values of the parameters:

Finally, you use the equation (1) to find the angle:

The angle below the horizontal is 12.60°
Answer:So, the wavelength is 400 nm and 4000 A°
