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

Explanation:
By the law of conservation of the momentum The car-bug system moment will remain the same before and after the collision. And since the mass of the car is much higher than the bug, the change in velocity of the car will be negligible as compared to the change in velocity of the bug and hence the change in momentum of the bug will be very large and change in momentum of the car will be negligible.

A quasar is an extremely bright, distant object visible to radio telescopes.
D. Giant kangaroo rats enrich the soil for plants with their piles of grass clippings in the California grasslands.
Explanation:
Giant kangaroo rats enriching the soil for plants with their piles of grass clippings in the California grasslands is an example of how biodiversity contributes to the sustainability of natural environment.
- Biodiversity refers to the variety of life forms in an area.
- The more diverse an ecosystem is, the more sustainable it is.
- Decaying plant pilings cut by the Kangaroos when they decay release useful nutrients to the soil.
- This would not be possible if an animal like the Kangaroo rats are not present.
