Fast moving neutron have a sufficient energy to penetrate the nitrogen nucleus and absorbedby it. Hence it make a intermdiate unstable element finallyit gives carbon-14 and a electron.
12) Radiocarbon is produced in the atmosphere as a result of
Answer is:
collision between fast neutrons and nitrogen nuclei present in the atmosphere

Answer is:
work done in rolling a stone is less than in lifting it
Explanation:
Work done in rolling is less than lifting due to a extra work has been done in lifting due to gravity means against the gravity but in rolling on a inclined plane we get a work done by gravity in downward direction along the gravity.
Answer is:
capillary action phenomenon
Explanation:
Blotting paper provide a capillary tube for ink so ink fill in capillary tube and absorbed by blotting paper continuously.
Answer is:
the level of the liquid in the two vessels are at the same height
Explanation:
Both the vessel has a liquid has a same heigt then the liquid are of the same desity, then work done will be zero.
Answer is:
both the heating effect of current and hysteresis loss
Explanation:
In alternating current a power dissipation due to heating effect p=i2R so heat is produce and eddy current produce in transformer also and they absorbed by circulating oil so heat produce due to both phenomenon.
