Answer:
C. zero for both
Explanation:
In case of solid metal sphere , when it is given any charge , all the charges are transferred on the surface and within surface no charge exists . In case of hollow metal sphere , all charges reside on surface . In this way , in both solid and hollow sphere , all charge reside on the surface and no charge resides inside it . Hence due to absence of any charge inside , there is no electric field inside the sphere in both the cases .
Hence in both the case electric field is zero .
option C is correct .
The particle that was given off in the reaction beta rays is β–. Option C
<h3>What is a nuclear reaction?</h3>
A nuclear reaction will involve the change in the nucleus of an atom. It often leads to the production of new nucleus. As we can see the equation, there was a transformation from nitrogen nucleus to oxygen atom.
Thus, the particle that was given off in the reaction beta rays is β–. The fact that the mass number remained the same but the atomic number increased by one unit from left to right implies that a beta decay has occurred.

Before the 4p orbit starts to fill, the element must have:
1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰,
which is Zn.
Depending on the number of electrons in the 4p, the element might be Ga to Kr, inclusive
Slash and burn farming is done by burning trees. When you burn trees, you are causing deforestation. It also is not healthy for humans
When air is warmer, the air particles move faster due to the heat, causing kinetic energy of the particles to increase. And as sound is produced when energy is transfered from one particle to another, with the particles moving faster, the energy will also be transfered faster, thus, allowing sound waves to travel faster in warmer air than in colder air
