Helium nuclei splitting to form hydrogen, and the Sun will no longer release energy will occur when all the hydrogen in the sun undergoes fusion.

<h3>What is Fusion?</h3>

This occurs when two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles.

In a situation where all the hydrogen in the sun has undergone fusion, the helium nuclei will split to form hydrogen, and the Sun will no longer release energy.

A red blood cell is 7 x 10-6 m in size. This means it is 7 __________ in size. What unit completes the sentence?
aalyn [17]

If a red blood cell is 7 x 10^-^6 m in size, it means that such a cell is 7 microns or micrometer in size. The unit that completes the sentence will, thus, be microns or micrometer.

According to international system of measurement:

  • 10^{-1} m = decimeter
  • 10^{-2} m = centimeter
  • 10^{-3} m = millimeter
  • 10^{-6} m = micrometer or micron
  • 10^{-9} m = nanometer

Thus, a measurement of 7 x 10^-^6 m is the same is 7 micons or 7 micrometer.

A uniformly charged rod (length = 2.0 m, charge per unit length = 3.0 nc/m) is bent to form a semicircle. What is the magnitude
Artist 52 [7]

Answer:

84.82N/C.

Explanation:

The x-components of the electric field cancel; therefore, we only care about the y-components.

The y-component of the differential electric field at the center is

$dE = \frac{kdQ }{R^2} sin(\theta )$.

Now, let us call \lambda the charge per unit length, then we know that

dQ = \lambda Rd\theta;

therefore,

$dE = \frac{k \lambda R d\theta }{R^2} sin(\theta )$

$dE = \frac{k \lambda  d\theta }{R} sin(\theta )$

Integrating

$E = \frac{k \lambda   }{R}\int_0^\pi sin(\theta )d\theta$

$E = \frac{k \lambda   }{R}*[-cos(\pi )+cos(0) ]$

$E = \frac{2k \lambda   }{R}.$

Now, we know that

\lambda = 3.0*10^{-9}C/m,

k = 9*10^9kg\cdot m^3\cdot s^{-4}\cdot A^{-2},

and the radius of the semicircle is

\pi R = 2.0m,\\\\R = \dfrac{2.0m}{\pi };

therefore,

$E = \frac{2(9*10^9) (3.0*10^{-9})   }{\dfrac{2.0}{\pi } }.$

$\boxed{E = 84.82N/C.}$
