Answer:
A- The ball has both kinetic and potential energy,
Explanation:
kinetic energy by virtue of its motion.
potential energy by virtue of its position. (It could roll off the edge of the tabel and convert gravity potential energy to kinetic energy)
A compound optical microscope or just a optical microscope is a microscope that uses light and has more than one lens.
Answer:
1000 N
Explanation:
The magnitude of the electrostatic force between two charged object is given by

where
k is the Coulomb constant
q1, q2 is the magnitude of the two charges
r is the distance between the two objects
Moreover, the force is:
- Attractive if the two forces have opposite sign
- Repulsive if the two forces have same sign
In this problem:
are the two charges
r = 3000 m is their separation
Therefore, the electric force between the charges is:

The bear is white in color because it is a polar bear.
<h3>What are the color of bears?</h3>
Bears are very large carnivorous animals found around the cold regions of the Arctic or North Pole.
The color of bears, may be brown, black or white depending on how far North the bears are found.
Bears found close to the Arctic or North pole are white polar bears.
Based on the description of the house, every side of the home faces South meaning that the individual lives in the North pole.
Therefore, the color of the bear will be white.
in conclusion, polar bears are white in color.
