In order to solve this question, we will need to know the E-field of a capacitor
E = sigma/epsilon naught
To find sigma (charge density), we will need to divide the total charge by the area
sigma = (.576 x 10^-9)/(4.952x10^-2)^2 = 2.34 x 10^-7
E = 2.34 x 10^-7/ (8.85x10^-12) = 26541.04 V/m
Answer:
Velocity (magnitude) is 98.37 m/s
Explanation:
We use the vertical component of the initial velocity, which is:

Using kinematics expression of vertical velocity (in y direction) for an accelerated motion (constant acceleration, which is gravity):

Now we need to find
as a function of
. We use the horizontal velocity, which is always the same as follow:

We know the angle at 3 seconds:

Substitute
in
and then solve for 

With this expression we go back to the kinematic equation and solve it for initial speed

The layer cake profile of different soil types having older soil type at the bottom of the layer is proved by the law of superposition.
Explanation:
The literal meaning of the word superposition means arranging one over the other. So the first generation soil or rocks will be deposited first on the mantle followed by the coming generation of soils and rocks. Due to different kinds of disasters like tides, earthquake, soil erosion etc., the new soil or rocks coming from any other region will get deposited on the surface of the old soil layer just like a layer cake format.
So the presence of older soil in the bottom most part of the mantle and the youngest soil or rock in the topmost surface of Earth is proved by the law of superposition.
