where is the end of spacE? |
|
Answer» Whether space ever ends is a hard question. There is a limit to the space that we can see, because if there is stuff beyond 15 - 20 billion light years (the age of the Universe) the light from there hasn\'t reached us yet. So we don\'t know. May be Black hole |

What is tydle effect |
| Answer» When a strong beam of light is passed through a true solution, we cannot see the light unless the eye is placed in the path but when the same beam of light is passed through a sol it becomes visible. What happens in this case of a sol is that the light scatters from the surface of the colloidal particles and reaches our eyes. This phenomenon is called\xa0Tyndall effect.When a\xa0colloidal solution\xa0is observed from the same way it will appear clean/translucent but whenever we observe that solution from the right angle then it will surely show some or more opalescence. We should also know that when we view this path of light from the right angle then this light is illuminated by bluish light. Faraday first observed this effect and was further studied by Tyndall that’s why it is called\xa0Tyndall effect.\xa0 | |

What is mean by periodicity |
| Answer» In the context of chemistry and the periodic table, periodicity refers to trends or recurring variations in element properties with increasing atomic number. Periodicity is caused by regular and predictable variations in element atomic structure.Mendeleev organized elements according to recurring properties to make a periodic table of elements. Elements within a group (column) display similar characteristics.The rows in the periodic table (the periods) reflect the filling of electrons shells around the nucleus, so when a new row begins, the elements stack on top of each other with similar properties. For example, helium and neon are both fairly unreactive gases that glow when an electric current is passed through them. Lithium and sodium both have a +1 oxidation state and are reactive, shiny metals. | |

To verify the ohm\'s law |
| Answer» Statement of Ohm\'s Law\xa0Ohm’s law states that at a constant temperature, current \'I\' through a conductor between two points is directly proportional to the potential difference or voltage \'V\', across the two points.\xa0Thatis, V propto I or frac{V}{I} = constant = R or V = IR Thus, the ratio V : I is a constant.\xa0Thisconstant is called as the resistance (R) of the conductor.\xa0Afterperforming experiment for different readings of V & I and recording the observations, if we plot current on the x-axis of a graph and voltage on the y-axis of the graph, we will get a straight-line. The gradient of the straight-line graph is related to the resistance (R) of the conductor.Related Theory:Resistance: Resistance is the property of a component which restricts the flow of electric current. Energy is used up as the voltage across the component drives the current through it and this energy appears as heat in the component. Resistance is measured in ohms, the symbol for ohm is an omega(Ω). Resistors connected in Series: When resistors are connected in series their combined resistance is equal to sum of thier the individual resistances.\xa0Forexample if resistors R1 and R2 are connected in series their combined resistance, R, is given by: R = R1+R2\xa0Resistorsconnected in Parallel: Whenresistors are connected in parallel their combined resistance is less than any of the individual resistances. Equation for the combined resistance R of 2 resistors R1 and R2 connected in parallel is given by: frac{1}{R}=frac{1}{R1}+frac{1}{R2} OR R =frac{1}{frac{1}{R1}+frac{1}{R2}} | |
