A white dwarf is:______.

Physics
1 answer:
bija089 [108]3 years ago
6 0

Answer:

the exposed core of a dead star, supported by electron degeneracy pressure.

Explanation:

A white dwarf is a low luminosity exposed core of a dead star having mass comparable to the sun but volume comparable to the earth . So its density is very high . These stars have lost the capacity to generate energy through the process of fusion . Due to high gravitational energy , it goes on shrinking but ultimately balanced by electron degeneracy pressure. It is not a main sequence star as it has lost the power of fusion .

Which is the second largest planet in our solar system.
hammer [34]

Saturn is the second largest planet in our solar system. At an average distance of 800 million miles (1.3 billion kilometers) from Earth, Saturn is the farthest planet that can be seen without a telescope. Saturn is the sixth planet from the sun. Because Saturn is so far away from the sun, Saturn is considered one of the outer planets. Despite it's large size, Saturn is the least dense planet in our solar system!

What is oxygen an example of? a mixture, an element, a compound, or a solution
soldi70 [24.7K]

Answer: element

Explanation:

Couldn't be a compound because contains same type of atoms. Can't be a mixture either because not physically mixed or anything. Isn't a solution ofc because oxygen is a gas.

Ivenika [448]

Complete Question

Complete Question is attached below

Answer:

q=1.558*10^{-9}c

Explanation:

From the question we are told that:

Side length s=1.13m

Left field strength E_l=784.75N/m

Right field strength E_r=776.38 N/m

Front field strength E_f=725.5 N/m

Back field strength E_b=749.54 N/m

Top field strength E_t=944.95 N/m

Bottom field strength E_{bo}=1082.58 N/m

Generally, the equation for  Charge flux is mathematically given by

\phi=EAcos\theta

Where

Theta for Right,Left,Front and Back are at an angle 90

cos 90=0

Therefore

\phi =0 with respect to Right,Left,Front and Back

Generally, the equation for  Charge Flux is mathematically also given by

\phi=\frac{q}{e_o}

Where

Area =L*B\\\\A=1.13*1.13\\\\A=1.2769m^2

Therefore

Q_{net}=E_{bo}Acos\theta_{bo} +E_tAcos\theta_t

Q_{net}=1082.85*1.2769*cos0=944.95*1.2769cos (180)

Q_{net}=176N/C m^2

Giving

q=\phi*e_0

q=176N/C m^2*1.558*10^{-12}c

q=1.558*10^{-9}c
