In concise physics it is written that one can prove Newton's first and third laws of motion using his second law. I can prove the first one. Can anyone tell me how to prove the third law? |

In Newton's first law of motion.... Is it okay if we write it as.... unless an external "unbalanced" force is applied on it. This statement is right but will they deduct marks for it being not exactly same to the def. given in the text book? |

WORKING OF THE CRT
Loads of people have trouble understanding this so I thought I'd help make it a little simpler :]
1) Filament heats the Cathode.
2) Cathode gets charged and emits the electrons
3) Grid(situated between Anode and Cathode) directs the entry of electrons
4) Anode provides Kinetic energy to the electrons
5) Deflecting plates direct the electrons to the flourascent screen.
This is the process of how an electrical signal is converted into a visual signal. Please correct me if I made any mistake.
Hope I helped :] |

Suresh applies a force of 6kgf to draw a 4.8kg bucket of water from a well using a single fixed pulley. Assuming all extra force is used to overcome frictional forces, calculate MA, VR, eff.
ans should be 0.8 MA, VR is 1 and eff. 80% right? |
