To solve this problem we will start by applying the given load ratio, and we will rely on the two types of distances given. Later we will use Gauss's law and through its integrals, in which it is equivalent to the potential we will obtain its value in the center of the sphere. Since it is uniformly charged we have to,
By Gauss Law
Here, E is the electric Field and is equal to
For 
being the Permeability constant at free space
Replacing with the previous value we have,
Then the value of the electric field is,
Now potential
Answer:
WEAR AND TEAR THEORY
Explanation:
Due to increasing age, the gravity ultimately compressed spine which consequently affect the height. This effect is best explained wear and tear theory. It states that continuing vandalized to cells and body systems over period is just because of effects of aging. This theory is deeply rooted in our mindset, and it's the theory that you might often hear in discussion and in our society.
Answer:
Explanation:
we know that acceleration =Δv/t
Δv=vf-vi
Δv=1.0-5.5=-4.5
now
a=-4.5/3.0
a= -1.5m/s²
Answer:
8400m
Explanation:
The engine that falls off would have the same constant horizontal velocity as the airplane's when if falls off if we ignore air resistance. So it would have a horizontal velocity of 280m/s for 30seconds before it hits the ground.
Therefor the horizontal distance the engine travels during its fall is
280 * 30 = 8400m

Answer:
The electric potential is 
Explanation:
From the question we are told that
The charge on each point is +Q
The length of the diagonal is 2a
Generally the electric potential is mathematically represented as
Here r is the distance from each vertices of the square to the center P which is evaluated as
So the potential at the center due to one charge is evaluated as
Given that there are four charge the net electric potential at the center P will be
