To solve this problem, apply the concepts related to the centripetal acceleration as the equivalent of gravity, and the kinematic equations of linear motion that will relate the speed, the distance traveled and the period of the body to meet the needs given in the problem. Centripetal acceleration is defined as,
Here,
v = Tangential Velocity
r = Radius
If we rearrange the equation to get the velocity we have,
But at this case the centripetal acceleration must be equal to the gravitational at the Earth, then
The perimeter of the cylinder would be given by,
Therefore now related by kinematic equations of linear motion the speed with the distance traveled and the time we will have to
Therefore the period will be 44.9s

Answer:
Water is a polar molecule
Explanation:
The general solubility rule is that like dissolves like. In short, polar solutes would dissolve in polar solvents. Non polar solutes also dissolves on non polar solvents.
NaCl is an ionic molecule which forms as a result of transfer of electrons from one atom to another. The transfer of electrons makes the atoms oppositely a charged ions and they become polar.
Water is made up of Hydrogen H⁺ ions and hydroxy ions OH⁻. Water is an heteronuclear covalent molecule. Here, there is an unequal sharing of electrons as one atom pulls the shared electron more closer. This leaves a partial negative charge on the more electronegative atom and a partial positive charge on the other.
This polar nature of water NaCl makes dissolution easy.
The magnet (south pole of the magnet) has magnetized the right side of the block.
<h3>
Direction of electric field in the magnetic material</h3>
The direction of electric field of the atom of the magnetic material is unpolarized.
From the diagram in the image, the right hand side of the magnetic material is being attracted to south pole of the magnet.
Thus, we can conclude that, the magnet has magnetized the right side of the block.
