Answer:
0.1 is the retention factor.
Explanation:
Distance covered by solvent ,
Distance covered by solute or ion,
Retention factor
is defined as ratio of distance traveled by solute to the distance traveled by solvent.
0.1 is the retention factor.
The electron has a higher frequency compared to the neutron. It can be explained by the way an electron orbits the nucleus of an atom.
According to Quantum Mechanics, electrons do not really orbit the nucleus of an atom. In fact, the most tightly bound state, the 1s orbital, has no angular momentum at all. This would be the state with the most "kinetic energy" and yet there is no "orbital" motion at all in this state.
<span>However, there are frequencies associated with each orbital.</span>
Answer:
Gene is the basic unit of inheritance.
Answer:
Density of the rectangular object = 4 / 6 = 0.67g/cm³
Explanation:
First find the volume of the rectangular object.
Volume of the rectangular object = 3 x 2 x 1 = 6cm³.
Density of an object = mass of the object / volume of the object
Therefore,
Density of the rectangular object = 4 / 6 = 0.67g/cm³
