1) Name two materials whose resistance doesn't change with the rise or fall in temperature. 2) Name two materials whose temperature increases with the rise in temperature. 3) Name two materials whose temperature decreases with the fall in the temperature. |
|
Answer» ans-1 The metalloids such as Silicon, Germanium (and others) are semiconductors, in these elements, electrical conduction OCCURS DUE to overlapping conduction bands of electrons.ans-2 The resistivity of metals (like copper, aluminum) increases with increase in temperature. Resistance of semiconductors( like silicon, germanium) decreases with increase in temperature.ans-3 Resistivity of semiconductors decreases with RISE in temperature. So, the THREE substances whose resistivity decreases with the rise in temperature are Graphite,Silicon and Germanium. |

What are 2 sources of power? |
|
Answer» Formal power anf ligitimate powerExplanation:Formal PowerFormal power is based on an individual’s position in an organization. Formal power can come from the ability to coerce or reward, from formal authority, or the CONTROL of information.The formal power is based on rank—for example, the fire chief or the captain.Legitimate PowerIn the formal groups and organizations, PROBABLY the most frequent access to one or more of the power bases is one’s structural position. This is called legitimate power.Legitimate power is also known as positional power. It’s derived from the position a PERSON HOLDS in an organization’s hierarchy.Job DESCRIPTIONS, for example, require junior workers to report to managers and give managers the power to assign duties to their juniors. For positional power to be exercised effectively, the person wielding it must be deemed to have earned it legitimately.An example of legitimate power is held by a company’s CEO. |

Two metal spheres, one of radius R and the other of radius 2R respectively have the same surface charge density s. They are brought in contact and separated. What will be the new surface charge densities on them? |
|
Answer» is the CHARGE on sphere with radius R and is the charge of the sphere with radius 2R. Since, they have equal surface charge density.When two charged surfaces are brought in contact, the same CONFIGURATION is maintained until both of them reach common potential. In other words, after separation the spheres are at same potential and have lost or GAINED some charge. Therefore (let and be the new charges) - Since, charge is always conserved. Using relations (1) and (2), Dividing by 4πr² on both SIDES, Note : SIGMA subscript r denotes surface charge density of sphere with radius r. Likewise, using relations (1) and (2), Dividing by 4π(2r)² on both sides, Note : Sigma subscript 2r denotes surface charge density of sphere with radius 2r. |
