Answer:
a) E = 0
b)
Explanation:
The electric field for all points outside the spherical shell is given as follows;
a)
From which we have;
E = 0/A = 0
E = 0
b)
By Gauss theorem, we have;
Therefore, we get;
The electrical field outside the spherical shell
Therefore, we have;
Answer:
A is a solid. C is a gas. In solid an liquid the particals are touching. In C, the particals have less affect on each other because they are so far apart.
Answer:
Explanation:
The sun is made up of 6 parts. Namely:
- The core
- The radiation zone
- The convection zone
- The photosphere
- The chromosphere and
- The corona
The convection area is just above the radiation zone. As materials from the suns core are heated, they rise above the radiation zone towards the EDGE of the convection area then sinks back again into the radiative zone for more heat.
The radiative zone is 12.6 million Fahrenheit hot and is just above the core.
The core of the son is not solid but plasma whose motion is like gas. Its temperature stands at 48 million Fahrenheit

The FIRST statement on the list is the definition of momentum, so that's the one that must be true.
