Why is VR(Velocity Ratio) greater than MA (Mechanical Advantage ) in a simple machine? |
|
Answer» The mechanical ADVANTAGE of a machine is always LESS than its velocity ratio.It is because mechanical advantage decreases due to the friction and weight of moving parts of the machine, but the velocity ratio remains constant. SIMILARLY, if mechanical advantage had been equal to the velocity ratio of the machine then the EFFICIENCY WOULD have been 100%, which is impossible. |

describe transmission of pressure in liquids? if you have plz send without pascal law if don 't have without so plz don 't send {physics} |
|
Answer» Pascal's LAW (ALSO Pascal's principle or the principle of transmission of fluid-PRESSURE) is a principle in fluid mechanics given by Blaise Pascal that STATES that a pressure change at any point in a confined incompressible fluid is TRANSMITTED throughout the fluid such that the same change occurs everywhere.Explanation:mark me as brain list |

Why does VR (Velocity Ratio) have no unit? |
| Answer» TY RATIO of simple MACHINE is the ratio of distance travelled by the effort to the distance travelled by THELOAD in the machine. As velocity ratio or ideal mechanical advantage is a simple ratio of two distances, it also does not have the unit. The FRICTION is not involved in it | |

a current of 0.8A drawn by a filament of electric bulb for 10 minutes find the amount of charge that flow through the circuit. |
|
Answer» :-I = 0.8 AT = 10 min ⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━★ To find:-The AMOUNT of CHARGE⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━★ Formula USED:-Current ( I )= Amount of charge ( Q ) / time ( t )Amount of charge ( Q )= Current ( I ) × time ( t )Q = I × t⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━★ SOLUTION:-converting Time:-⇒ 1 min = 60 sec⇒ t = 10 × 60 ⇒ t = 600 secTherefore the time is 600 seconds.⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━★ The amount of charge:-⇒ I = Q/t⇒ Q = I × t⇒ Q = 0.8 × 600⇒ Q = 480Therefore the amount of charge is 480 coulomb |

you must have observed the inside of the cinema, what measure have been thicken to reduce the controversy there? |
|
Answer» heatres are closing around the world. Jobs are being culled. No one knows when projectors will be fired up again. Cinema is far from unique in being an industry under threat in the time of Covid-19. But there is a PARTICULAR irony in the FACT that many of us have turned to streaming platforms to deliver entertainment to fill the long hours of isolation, often watching content ORIGINALLY made for the silver screen. Audiences have increasingly been consuming more films at home anyway, of course. But now that trend has BECOME a fact of life, many are questioning whether the culture of cinemagoing will resume in the same way once the pandemic abates |

Describe the working of a syringe??for class 8th |
|
Answer» A syringe is a pump consisting of a sliding plunger that fits tightly in a tube. The plunger can be pulled and PUSHED inside the PRECISE cylindrical tube, or barrel, letting the syringe draw in or expel a liquid or gas through an ORIFICE at the open END of the tubeThe syringe works on the existence of atmospheric pressure. When the nozzle of a syringe is dipped in a liquid and its piston is WITHDRAWN, the pressure inside the syringe is lower. The greater atmospheric pressure acting on the surface of the liquid pushes the liquid up into the syringe.Explanation:please mark me as brainliest |
