Answer:
Vb = k Q / r r <R
Vb = k q / R³ (R² - r²) r >R
Explanation:
The electic potential is defined by
ΔV = - ∫ E .ds
We calculate the potential in the line of the electric pipe, therefore the scalar product reduces the algebraic product
VB - VA = - ∫ E dr
Let's substitute every equation they give us and we find out
r> R
Va = - ∫ (k Q / r²) dr
-Va = - k Q (- 1 / r)
We evaluate with it Va = 0 for r = infinity
Vb = k Q / r r <R
We perform the calculation of the power with the expression of the electric field that they give us
Vb = - int (kQ / R3 r) dr
We integrate and evaluate from the starting point r = R to the final point r <R
Vb = ∫kq / R³ r dr
Vb = k q / R³ (R² - r²)
This is the electric field in the whole space, the places of interest are r = 0, r = R and r = infinity

here try this! i hope this helps
Explanation:
There are many advantages when we compare strength training with other forms of training. For example, the biggest benefit would be the increase of muscle mass due to us using the muscle more and for harder movements than usual. Strength training can preserve the mass that we lose with age. Bones also get stronger when we train so they are harder to fracture. We get more joint flexibility from the movements we do. So things as arthritis can be avoided or at least feel better.

Answer:
Hey
I have no idea when YOUR assignment is due.
Newtons 1rst law:
An object that has constant motion will remain at that speed unless acted on by an external force.
Newtons 2nd law:
F=ma (force=mass*acceleration)
Newtons 3rd law:
when a force is applied to an object, there will be an opposite but equal reaction.
Acceleration:
How much your speed increases/decreases per unit of time.
I wrote all that^
