How does a lightning conductor protect a tall building? |
|
Answer» In order to PROTECT house or tall building from damage due to the lightning, Benjamin Franklin first discovered a DEVICE called the lightning conductor in 1749. It is just a copper strip which is fixed to the outside wall of the building and its lower end put deep in the ground. The other end of the copper strip projects above the highest point of the building with many sharp spikes. When a thunderstorm began, the clouds become heavily charged. Huge electric sparks, called lightning, often happens between two charged clouds or between a cloud and the earth. If it occurs between a cloud and the earth, it becomes a great concern to man. It generally happens between two heavily charged clouds and activates opposite charge on the highest structure on the ground. As a result, trees, towers and tall buildings may be stroked by the lightning. The protective action of a lightning conductor is BASED on the discharging action of points. When a heavily charged cloud move over the lightning conductor, opposite charge is activated on the spikes of the lightning conductor and the same charge passes on to the ground. Due to the discharging action of the spikes, an electric wind is established which rises up towards the cloud and partly deactivates the charge on the cloud. Therefore, the possibility of lightning strike gets DECREASED significantly. Sometimes even after this process, the clouds may still have some charge, so that the lightning flash may pass and hit the ground. As the spikes of the lightning conductor are nearest to the cloud, the flash hits the spikes. Being grounded, the spikes provide the electricity low resistance PATH, so that it can easily run to the earth. In this way, the discharge flow to the ground via the thick copper conductor and the building or tall structure therefore remains safe. |

Explain capacitance |
|
Answer» Capacitance is the ability of a component or circuit to collect and store energy in the form of an electrical charge. CAPACITORS are energy-storing devices available in many sizes and shapes.Explanation:Capacitance is the ratio of the change in electric charge of a system to the CORRESPONDING change in its electric potential. There are two closely related notions of capacitance: self capacitance and mutual capacitance.[1]:237–238 Any object that can be electrically charged exhibits self capacitance. A material with a large self capacitance holds more electric charge at a given voltage than one with low capacitance. The notion of mutual capacitance is particularly important for understanding the operations of the capacitor, one of the three elementary linear electronic components (along with RESISTORS and inductors). The capacitance is a function only of the geometry of the design (e.g. area of the plates and the distance between them) and the permittivity of the dielectric material between the plates of the capacitor. For many dielectric materials, the permittivity and thus the capacitance, is INDEPENDENT of the potential difference between the conductors and the total charge on them. The SI unit of capacitance is the FARAD (symbol: F), named after the English physicist Michael Faraday. A 1 farad capacitor, when charged with 1 coulomb of electrical charge, has a potential difference of 1 volt between its plates.[2] The reciprocal of capacitance is called elastance. |

Panishment will help the students to learn the subject? do you agree? write an essay |
|
Answer» Yes , certainly why not. A teacher is a person that has the responsibility to built a nation . if he/ she does not teach what is right and WRONG for us , then we can not run a GOOD and healthy society. OK let's take a example imagine a boy who do not obey the laws made in school then how can you imagine that he will follow the country law and society, he will become a ulcer for the society and illegal activities , he will always DISTURB his family and due to this family get spoiled and their generation will lost their future and remember that by the bonding of each unit family now you can imagine the importance of teacher in our world . That why its very important that teacher should punish his student so that they learn from their early STAGE what is wrong and what is right . What are the good values , without they can not distinguish between good and bad. I know it MAY feel harsh to the student but they will learn a good lesson and also the punishment should be in that way that student do not feel humiliated and molested also .Explanation:follow me |

law of conservation of momentum states that in the absence of a net external force on the system - of the system |
|
Answer» An isolated system is defined to be one for which the NET EXTERNAL force is zero (Fnet = 0). During projectile motion and where air resistance is negligible, momentum is conserved in the HORIZONTAL direction because horizontal FORCES are zero. Conservation of momentum applies only when the net external force is zero. conserved |

The acceleration of a 50-kg block of cement that is pulled sideways with a net force of 250 N. |
|
Answer» tion:FIRST, we need to use NEWTON's second law of motion, which states thatF=ma F is the FORCE in newtons (N) m is the mass of the object in kilogramsa is the acceleration of the object in m/s2 So, plugging in,600=50a , a=60050=12 So, the acceleration is right now 12m/s2 . But, it is being pulled up, so gravity, which has an acceleration of ≈9.8m/s2 , pulls it in the opposite direction, which is down.That means, that we need to subtract.12m/s2−9.8m/s2=2.2m/s2 |

Derive expression for 2 capacitors in paralell |
|
Answer» tion:Here is a dc circuit with a BATTERY using two electrolytic capacitors connected in parallel. The goal is to DERIVE the formula for an equivalent capacitor. Each capacitor has holds a charge Q, has a voltage V across it, and has a capacitance C, as shown in the diagram above.The voltage V1 across capacitor C1 is q1 / C1. The voltage V2 across capacitor C2 is q2 / C2.The total voltage Vtot across the parallel combination is qtot / Ctot. This is the ratio of total charge and total capacitance.The total charge qtot is the sum of q1 and q2. By substituting the previous expressions into this equation, we get the following expression.This is the same as the previous equation but in terms of C and V, thus eliminating the charge q.Capacitors in parallel have the same voltage; therefore, Vtot is the same as V1 and V2.Hence, we divide throughout by V in the previous equation, thus cancelling out V1 and V2, GIVING the final expression below. |
