Answers
Answer:
solid uniform iron cube of volume 1ltr is fastened to ont end of an ideal string,the other end of which is attached to a light plastic bucket containing water.the string passes over an ideal pulley and the iron cube is suspended in the water,as shown in fig.it is found that the system is in equilibrium.(water doesn't split during the process performed in options).mark the correct options.assuming density of water=1gm/cc and iron = 7.8gm/cc36. x का वह मान जो समीकरण
10(x +6)+8(x-3)=D5(5r-4)
को संतुष्ट करता है वह निम्न समीकरण को
संतुष्ट करता है:
(1) 3(3x-5) = 2x + 1
.(2) 2(x+3)= 5(x-5)+4
(3)-5(x-5) = 2(x-3)+5
(4) 5(x-3) =x+5
Answer:
Which of the following is smallest in size N3 O2 F Na+?
Make life easier by first sorting them into Periodic Table order: N3- O2- F- Na+ Mg2+ Al3+ These are all isoelectronic with the structure 2,8. The smallest ion will be the one with the largest number of protons – Al3+; the biggest, the one with the least protons – N3-.
