Explanation :
When an electron jumps from one energy level to another, the energy of atom gets changed.
If a photon gets absorbed, the electron will move to higher energy levels and then fall back to the lower energy levels. Then each time a photon will be absorbed whose energy is given by difference between the initial and final energy levels i.e
In Balmer series, the transition is from higher energy levels to n = 2.
So, the necessary condition for Balmer series is that the electron should be at first excited state or n = 2 level as shown in figure.
Gyroscopic wander can be divided into two categories and these are:
- Drift
- Topple
<h3>What is
gyroscopic wander?</h3>
Gyroscopic wander can be defined as a movement of the spin axis (axis of rotation) away from a specific fixed direction.
Based on scientific information and records, there are two main types of gyroscopic wander and these include the following:

Answer:An object can be considered a point object if during motion in a given time it covers a distance much greater than its own size.
Explanation:
Solid state drives. Hard disk drives use a rotating platter that has data written by magnets, so having a strong magnet near one will corrupt its data. Solid state drives on the other hand, use electrical switches and no mechanical pieces. They are also generally faster than hard drives.
