The magma cools very slowly so that the crystals of different minerals have time to grow. The magma molecules in have time to organize themselves into crystal formations before the magma hardens. The naked eye helps the Intrusive rocks that has large crystals be seen.
Answer: a) r= 4.82 * 10^-4 m ; b) 1420 V
Explanation: In order to solve this problem we have to take into account that potential for a sphere respec to V=0 at the infinity, which is given by:
V=k*Q/r where r is the radius of the drop
then we have
r=k*Q/V=9*10^9*38pC/710V= 4.82 * 10^-4 m
Finally if we join two drop to form one with the same radius but with twice charge the resultant potential is:
V= k*2*Q/(r)= 710*2= 1420 V
Answer:
A) No work was done on the box.
Explanation:
None. We already have more than we need ... provided only that the lane is on Earth.
Weight = (mass) (gravity).
On Earth, 'gravity' = 9.8 m/s^2.
Weight of the ball =
(4.5 kg) (9.8 m/s^2).= 44.1 newtons.
(roughly 9.9 pounds)
