The strength of the electric field at a certain distance from a point charge is represented by E. What is the strength of the el
Nana76 [90]

Answer:

E

Explanation:

Using Coulomb's law equation

Force of the charge = k qQ /d²

and E = F/ q

substitute for F

E = ( K Qq/ d² ) / q

q cancel q

E = KQ / d²

so twice  the distance of the from the point charge will lead to the E ( electric field ) decrease by a 4 = E/4. E is inversely proportional to d²

Tĩnh lực tĩnh điện [lực cu lông] giữa 2 điện tích điểm q1,q2 biết q1=2.10-9 q2=4.10-9 r=3cm
Anettt [7]
  • q1=2×10^{-9}C
  • q2=4×10^{-9}C
  • Radius=3cm=0.3m

Using coulmb's law

\\ \bull\tt\dashrightarrow F=k\dfrac{q1q2}{r^2}

\\ \bull\tt\dashrightarrow F=8.98\dfrac{2\times 10^{-9}\times 4\times 10^{-9}}{(0.3)^2}

\\ \bull\tt\dashrightarrow F=8.98\dfrac{8\times 10^{-18}C^2}{0.09m^2}

\\ \bull\tt\dashrightarrow F=\dfrac{71.84\times 10^{-18}C^2}{0.09m^2}

\\ \bull\tt\dashrightarrow F=798.2\times 10^{18}Nm^2/C^2

\\ \bull\tt\dashrightarrow F=7.9\times 10^{16}Nm^2/C^2

Explain how energy from the Sun created music.
elixir [45]

-- Energy from the sun was absorbed by grass, grain, and hops, making it possible for them to grow.

-- The grass was eaten by livestock, and turned into stored beef energy.

-- The grain was harvested, pounded into flour, baked, and turned into stored bread energy.

-- The hops were harvested, soaked, and turned into stored beer energy.

-- Johannes Brahms ate beef, which his body turned into brain and muscle energy.  Ludwig van Beethoven drank beer, which his body turned into energy and inspiration.  John Phillip Sousa ate bread, which his body turned into leg energy to march with.

-- All of these individuals, and a lot of others, composed music which nobody had ever heard before, using the solar energy they absorbed from the stuff that they ate and drank.
