How does the contour plowing technique conserve soil?

Vedmedyk [2.9K]

Contour plowing created grooves in the soil. Because the bottom of each groove is at the same elevation throughout its length, rainfalls will get trapped in each groove instead of running rapidly downhill toward the stream, carrying the top soil with it

How far away can a proton and an electron be from each other, such that they still exert an electric force on each other of magn

pogonyaev

Answer:

$\sqrt{ \frac{2.3 *10^{-28} }{F} }$

Explanation:

Total force = Force due to gravity + Force due to charges

Total force = $\frac{GMm}{r^{2} } + \frac{kQq}{r^{2} }$

r is the separation between particles.

Charge of a proton(Q) = - (charge of an electron(q) ) = 1.6 * 10^-19 coulombs

Mass of a proton (M)= 1.67×10^-27 kilograms

Mass of an electron (m) =9.11 × 10^-31 kilograms

G=6.67 ×10^−11 N⋅m^2/kg^2

k=8.99 * 10 ^9 N.m^2 / C^2

Plugging in values:

Force due to gravity= (6.67 *10^−11)(1.67 * 10^-27)*(9.11 * 10^-31) /r^2 =1.01 * 10^-67 / r^2

Force due to charges : (8.99 * 10 ^9)*(1.6 * 10^-19)*(1.6 * 10^-19) / r^2 = 2.3 *10^-28 / r^2

We can observe that force due to charges is too large as compared with force due to charge. The ratio of Fc to Fm is 2.3* 10^39. It means that we can ignore force due to gravity.

Total force = Force due to charges.

F = 2.3 *10^-28 / r^2

r = $\sqrt{ \frac{2.3 *10^{-28} }{F} }$
