i have got it . . . its mass is 0.2 kg and F=p*g*v And v=F/p*g v=2/1000*10 v=0.0002 m^3 m=w/g m=10/10 m=1 kg density = Mass/Volume =1/0.0002 density=5000 kgm^-3

why don't u solve it and give me answer? :P

1 gcm^3 but i still didn't get it how can i find density when i don't have the values of volume and mass?

it tells me . . when an object is immersed in a liquid ,the liquid applies a buoyant force which is equal to the weight of water displaced by the object.

Findind density ! A piece of metal of unknown volume is immersed in water by means of a thread. Before lowering the piece in water , the tension in the thread is 10 N . The tension in the thread in when the piece is immersed in water is 8 N. Find the Density of the metal? My...

Thanks :)

so if the current really flows from - to + , then why my book is insisting me to believe that it flows from + to -? ? and the electrons(-) will surely be attracted towards the (+) terminal of the battery, and if there are protons(+) they would love to go towards the (-) terminal of the...

so here is my problem. . my physics book is trying to explain me about conventional current and i am not getting it ! urghh. .so at last i decided to copy paste what my book says so some 1 else can explain me better . . so here it is... (text from book) Now let us see how current flows in...

thanks fss Some other Book Please ... i am waiting . . :)

i am 10th grade student ( O Level ) I need a Book,which clear my concepts and about Physics. . I want to study Science subjects in future. . so i really want to have a good base in Physics. so please suggest some basic level books for me . . mentioning some of the topics: wave sound...
