What will happen to the brightness of the bulb if the wire is shorter? |
|
Answer» If you use the same battery but replace a thick wire with a thinner ONE, the ELECTRIC current will GET smaller and a light bulb in the circuit should get dimmer. Using a LONGER wire will also INCREASE resistance. ... But a typical light bulb still has about 2,000 times more resistance than the wireHope it helps you |

Buoyancy and floatation are significant for * |
|
Answer» G:-Buoyancy is important in swimming because it helps the swimmer to stay CLOSER to the surface. This is because the PRESSURE EXPERIENCED by the swimmer under the water is more than the pressure experienced above. This is also the reason why SWIMMERS can FLOAT on the surface of the water. |

if the temperature of an object increases more than other object is it because it is a better thermal conductor or is it beacsue it has low thermal capacity |
|
Answer» the major EFFECTS of HEAT transfer is temperature change: heating INCREASES the temperature while cooling decreases it. We assume that there is no phase change and that no work is done on or by the system. Experiments SHOW that the TRANSFERRED heat depends on three factors—the change in temperature, the mass of the system, and the substance and phase of the substance. |

Distinguish between conductors,insulators and semiconductors based on the band theory of solids |
|
Answer» In insulators the electrons in the valence band are separated by a LARGE gap from the CONDUCTION band, in conductors like metals the valence band OVERLAPS the conduction band, and in semiconductors there is a small ENOUGH gap between the valence and conduction bands that thermal or other excitations can bridge the gap.Explanation:CLASSIFICATION of Metals, Semiconductors, and Insulators. In case of metallic conductors, conduction band overlaps on the electrons in the valence band. In insulators, there is a large gap between both these bands. ... Semiconductors have a small gap between both these bands. |

Why is there a need of second condition for equilibrium if a body satisfies first conditions for equilibrium? |
|
Answer» tion:The second condition necessary to achieve equilibrium involves avoiding accelerated rotation (maintaining a constant angular velocity ). A rotating body or system can be in equilibrium if its rate of rotation is constant and REMAINS UNCHANGED by the FORCES acting on it.A body is said to be in equilibrium if no net force acts on it.”Newton’s first law of motion tells us that a body continues its state of rest or of uniform motion in a straight line if no resultant or net force acts on it. For example, a BOOK lying on a table or a picture hanging on a wall is at rest. The weight of the book acting downward is balanced by the upward reaction of the table.In the CASE of objects moving with uniform velocity, the resultant force acting on a leveled road and an airplane flying in the air with uniform velocity are the examples of bodies in equilibrium. |

Answer» The nucleoid (meaning nucleus-like) is an irregularly shaped region WITHIN the prokaryotic cell that contains all or most of the genetic material.[1][2][3] The CHROMOSOME of a prokaryote is circular, and its length is very large compared to the cell dimensions needing it to be compacted in order to fit. In contrast to the nucleus of a eukaryotic cell, it is not surrounded by a nuclear MEMBRANE. Instead, the nucleoid forms by condensation and functional arrangement with the help of chromosomal architectural proteins and RNA MOLECULES as well as DNA supercoiling. The length of a genome widely varies (generally at least a few million base pairs) and a cell may CONTAIN multiple copies of it. |
