Where do we get electricity form ?why do we need a switch in the torch |
|
Answer» tion:The three major categories of energy for electricity generation are fossil FUELS (coal, natural GAS, and petroleum), NUCLEAR energy, and renewable energy sources. Most electricity is generated with steam turbines using fossil fuels, nuclear, BIOMASS, geothermal, and solar thermal energy.The switch in a torch provides a mechanism through which electricity is passed to the bulb. As SOON as the switch is put on, the circuit existing in the torch closes resulting in the flow of electricity which is then dissipated through the bulb.Please mark it as Brainliest answer |

Do a little research on the life history of famous scientist Sir Isaac Newton. Find out the inventions made by him. And write down the famous laws of motion given by him. |
|
Answer» he made two DIFFERENT types of telescopes one of which is most common now called the reflecting telescope and then he made his first telescope called the Newtonian telescope. his famous laws of motion are, the first law, an object will not CHANGE its motion unless a FORCE acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they APPLY forces to each other of equal magnitude and opposite direction.Explanation: there you go, my friend |

BOTH QUESTION ARE REQUIRED TO BE ANSWERED.. |
|
Answer» Answer(1)Speed is the distance travelled in a set amount of TIME. More force will give an object greater speed. Greater MASS requires more force to move.Answer (2)When two forces act in the same direction, they add together. When forces act in opposite DIRECTIONS, they are combined by subtracting the smaller force from the larger force. The direction of the RESULTING force (resultant) is the direction of the larger original force. |

How muchamount ofheat required to changewaterat 30°c at steam 100 degree celcius |
| Answer» EXPLANATION:I first take care to look up the specific heat of the WATER in its three phases. Here is the result:“The specific heat capacity or the amount of heat needed to RAISE the temperature of a specific substance in a specific FORM one degree Celsius, for water is 4.187 kJ/, for ICE 2.108 kJ/, and water (steam) 1.996 kJ/.”The questioner asks about two phases: from 30 - 100 degC, and 100 - 150 deg CHence we need 4.187 kJ x 70 plus 1.996 kJ x 50 plus the biggest contribution: latent heat of vaporization of water. I see that “ The heat of vaporization of water is about 2,260 kJ/kg”.The sum of these contributions is 293.09 + 99.8 + 2260 = 2652.89 kJ per kg.kg Kkgkgvapour | |

A pendulum oscillates 50 times in 5 seconds. Find its time period & frequency.Don't SPAM |
|
Answer» -NUMBER of oscillations by the pendulum = 50 timesTotal time taken by the pendulum = 5 secTo Find :-The time period.The frequency.Analysis :-Here we are given with number of oscillations and the time taken by the pendulum.Firstly, divide the total time taken by the number of oscillations in order to find the time period.Then using the FORMULA of frequency, substitute the values we GOT such that, frequency is equal to ONE divided by time period.Solution :-Using the formula,Given that,Time = 5 secNo. of oscillations = 50 timesSubstituting their values,⇒ t = 5 / 50⇒ t = 0.1 secUsing the formula,Given that,Time period = 0.1 secSubstituting their values,⇒ f = 1/t⇒ f = 1/0.1⇒ f = 10 HzTherefore, the frequency is 10 Hz. |

What is the difference between photoemissive , photovoltaic and photo conductive cells ? Explain in detail. |
|
Answer» ovoltaic mode the PHOTODIODE is zero biased. The FLOW of current out of the device is restricted and a voltage builds up. This mode of operation exploits the photovoltaic effect, which is the basis for solar CELLS. The AMOUNT of dark current is kept at a minimum when operating in photovoltaic mode.In photoemissive type devices, once the radiation drops over a cathode can cause emission of electrons from the cathode PLANE. photoelectric-transducer. The output of the PV cells can generate a voltage which is relative to the intensity of radiation. |
