In comparing sunspots to other areas of the sun's surface one can say that sunspots are...?

taurus [48]

Answer:

D. Cooler

Explanation:

The Sun's surface has a temperature ranging from 6 000 Kelvin, thus it is very hot. The radioactive reaction in the core of the Sun is a nuclear fusion reaction. This reaction ensures continuous release of high energy from the surface of the Sun.

But during the reaction, some parts becomes cooler than other parts on its surface. Which is due to the release of high amount of energy into space. The Sun's spot can be found in the cooler part of the Sun.

A small metal bead, labeled A, has a charge of 26 nC . It is touched to metal bead B, initially neutral, so that the two beads s

adell [148]

Answer:

$q_A=25.953\ \rm nC$

$q_B=0.047\ \rm nC$

Explanation:

Given:

Total initial charge on bead A=26 nC
The distance between them=5 cm
Magnitude o the force between them $=4.4\times10^{-4}$

Using coulombs law the force between two charged particle is $\dfrac{q_Aq_B}{4\pi \epsilon_0 r^2}$

where r is the radial distance between them

According to question we have

$4.4\times10^{-4}=\dfrac{q_Aq_B\times9\times10^9}{0.05^2}\\\\4.4\times10^{-4}=\dfrac{q_A(q_A-26\times10^{-9})\times9\times10^9}{0.05^2}\\q_A=25.953\ \rm nC\\q_B=0.047\ \rm nC$
