A solid uniformly charged insulating sphere has uniform volume charge density p and radius R. Apply Gauss's law to determine an
RUDIKE [14]

Answer:

electric field E = (1 /3 e₀) ρ r

Explanation:

For the application of the law of Gauss we must build a surface with a simple symmetry, in this case we build a spherical surface within the charged sphere and analyze the amount of charge by this surface.

The charge within our surface is

 

     ρ = Q / V

     Q ’= ρ V '

The volume of the sphere is V = 4/3 π r³

     Q ’= ρ 4/3 π r³

The symmetry of the sphere gives us which field is perpendicular to the surface, so the integral is reduced to the value of the electric field by the area

      I E da = Q ’/ ε₀

      E A = E 4 πi r² = Q ’/ ε₀

      E = (1/4 π ε₀) Q ’/ r²

Now you relate the fraction of load Q ’with the total load, for this we use that the density is constant

     

      R = Q ’/ V’ = Q / V

How you want the solution depending on the density (ρ) and the inner radius  (r)

      Q ’= R V’

      Q ’= ρ 4/3 π r³

      E = (1 /4π ε₀) (1 /r²) ρ 4/3 π r³

     E = (1 /3 e₀) ρ r

Consider a particle moving along the x-axis where x(t) is the position of the particle at time t, x' (t) is its velocity, and x'
nignag [31]

The position of the particle is given by:

x(t) = t³ - 12t² + 21t - 9

Differentiate x(t) with respect to t to find the velocity x'(t):

x'(t) = 3t² - 24t + 21

Differentiate x'(t) with respect to t to find the acceleration x''(t):

x''(t) = 6t - 24

In the box provided explain why living organisms contain more hydrogen atoms than any other atoms
leva [86]

Answer:it is due to present of water amount in our body. Our body consists 70%of water and 1/3of oxygen and 2/3 of hydrogen.

Explanation: human body consist of 1/3 of oxygen and 2/3 of hydrogen because oxygen contain 16 times more mass than hydrogen atom, hydrogen has only 1 proton so its atomic no. is 1  whereas oxygen has 8 proton and 8 neutrons so its atomic no.is 8 and mass is 16 so overall it takes 16 hydrogen atoms to equal to the mass of 1 oxygen atom.
