What has more kinetic energy 10kg of bees flying at 10m/s or 10kg of birds flying at 10m/s? why?

Both of them will have same kinetic energy.

i.e,          K.E = 1/2 mv² .

Where, K.E is kinetic energy,

            m is mass of the object

            v is the velocity of the object

Result: Both bees and birds have same kinetic energy.

first one is the correct answer

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
