Answer:
The key difference between diamagnetic, paramagnetic and ferromagnetic materials is that diamagnetic materials are not attracted to an external magnetic field, and paramagnetic materials are attracted to an external magnetic field whereas ferromagnetic materials are strongly attracted to an external magnetic field.
The answer to your question is SPEED.
The energy is involved in ionization, electron affinity etc
The following are the conditions that favor the creation of covalent bonds since they are generated by the mutual sharing of electrons:
- Electron affinity, first. If both atoms have a strong electron affinity, a covalent link is often preferred between them.
- The energy of ionization. The ionization energy of the two atoms participating in the bonding process should be high.
- Atomic Dimension. The atoms that form covalent bonds should have lower atomic sizes. Stronger covalent bonds are created when atoms have smaller atomic radii.
- Electronegativity. Both atoms' electronegativities ought to be high. The two atoms' electronegativities should differ as little as possible.
- In order to establish covalent bonds, the atoms' high ionization energy is involved.

Matter cannot be created or destroyed under normal conditions. The big rock is weathered by the river water and goes through wear and tear because of its motion, and finally turns into gravel. So the lost part of the rock has been converted to soil .-.
Answer:
Explanation:
The given time is 1 / 4 of the time period
So Time period of oscillation.
= 4 x .4 =1.6 s
When the block reaches back its original position when it came in contact with the spring for the first time , the block and the spring will have maximum
velocity. After that spring starts unstretching , reducing its speed , so block loses contact as its velocity is not reduced .
So required velocity is the maximum velocity of the block while remaining in contact with the spring.
v ( max ) = w A = 1.32 m /s.
