Answer:
![r =3 *\sqrt{2} = 4.24 cm](https://tex.z-dn.net/?f=r%20%3D3%20%2A%5Csqrt%7B2%7D%20%3D%204.24%20cm)
Explanation:
given data
Radius of sphere 3.0 cm
charge Q = 2.0 m C
We know that maximum electric field is given as
![E_{MAX}= \frac{KQ}{r^{2}}](https://tex.z-dn.net/?f=E_%7BMAX%7D%3D%20%5Cfrac%7BKQ%7D%7Br%5E%7B2%7D%7D)
electric field inside the sphere can be determine by using below relation
![\frac{KQ}{r^{2}}= \frac{1}{2}*\frac{KQ}{R^{2}}](https://tex.z-dn.net/?f=%5Cfrac%7BKQ%7D%7Br%5E%7B2%7D%7D%3D%20%5Cfrac%7B1%7D%7B2%7D%2A%5Cfrac%7BKQ%7D%7BR%5E%7B2%7D%7D)
![r = \sqrt{2}R](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%7B2%7DR)
![r =3 *\sqrt{2} = 4.24 cm](https://tex.z-dn.net/?f=r%20%3D3%20%2A%5Csqrt%7B2%7D%20%3D%204.24%20cm)
<h3><u>Answer;</u></h3>
100 times
<h3><u>Explanation;</u></h3>
- The largest stars are 100 times the mass of the Sun.
- <u>The giant stars are about 10 to 100 times the radius of the sun</u>, which means they are 100 times brighter than the sun.
- <em><u>The largest known star in terms of mass and brightness is known as the Pistol Star. It is believed to be 100 times as massive as our Sun, and 10,000,000 times as bright.</u></em>
It would be Thermal Radiation
If we use the equation:
N2 + 3H2 --> 2NH3
Then
1 mol of Nitrogen required 3 moles of Hydrogen
x mols : 6.34mols
X = 6.34/3
X = 2.11 moles of Nitrogen are required.
Answer: false
