Only under the most bizarre circumstances would you successfully destroy a tank with frag grenades. Frags throw off tiny bits of metal, known as shrapnel, and tanks are more than sufficiently armoured to withstand it. When tanks had been defeated by soldiers with frag grenades, it's because the soldiers were able to climb onto the vehicle, force open the hatches, and drop the frags inside the vehicle, killing the crew. Unless some freak accident caused the ammo carried inside the tank to go off through sympathetic detonation, however, the tank itself remained fully serviceable.

Surprisingly few ! The 'super powers' have enough nuclear weapons between them - to destroy humanity many times over !
Vinegar can destroy almost anything within a certain time frame, to destroy a penny it will take up to a few milliseconds
It is difficult to answer how many nuclear bombs it would take to destroy England due to the fact that there are a variety of different nukes. It would most likely take around a couple of dozen.
To destroy metal you would need to put it in extreme heat (fire) or cut it with a crystal saw. :)
It took minutes to destroy but years to build
That would depend on yields. Also simply killing all humans would take much much less.
There hasn't been a test on that yet, it would also depend on how big the warheads carried were.
Just one.
