They will become equally negative charges, I believe.
There was no need to. They must have been able to survive just fine without the use of other cells
Think about the formula for potential energy. (Surely you remember it):
Potential energy = (mass) x (acceleration of gravity) x (height)
-- The mass on the end of the pendulum doesn't change.
-- The acceleration of gravity doesn't change.
-- The only thing that changes is the height of the mass on the end.
So the potential energy is lowest when its height is the lowest.
That's position <em>B </em>.
Answer:
m(P4) = 46.175 (grams)
m (KClO3) = 149 (grams)
Explanation:
1) n(P4) = n(P4O10);
m(P4)/M(P4) = m(P4O10)/M(P4O10);
m(P4) = M(P4)*m(P4O10)/M(P4O10)
= 123.90*105.8/283.89
= 46.175 (grams)
2) Analogously, 10n(P4O10) = 3n(KClO3)
m (KClO3) = 10M(KClO3)*m(P4O10)/3M(P4O10)
= 10*122.55*105.8/283.89/3
= 149 (grams).
i would choose steel because the steel used for normal construction have several hundred Mega Pascal strength. one of the special feature of steel is its ductility. it is the deformation capability before the final breakage.
