Answer: a) the force will be repulsive
b) the ratio of the new force to the old force will be 2
c) O
Explanation:
a) since charge -Q is moved from A to B, this implies that sphere A is negatively charged. The two spheres are now negatively charged and will repel themselves.
b) initial force will be -q(-Q)/d2
Adding extra charge -Q will cause change on B to become -2Q
The new force will be - 2Q(-q)/d2
Dividing new force by old force will give 2
C) if B is neutralized, the net charge becomes 0 and there will be no force on it.
The digestive system digests and makes nutrients out of food while the circulatory system distributes and circulates the nutrients i believe?
Answer:
B
Explanation:
Heat increase molecular motion
Potential energy is highest at the top of the loop, and kinetic energy is highest at the bottom of the loop.
My guess would be about 10 years because stars are hot balls of light that are reflections from years ago so it would most likely take awhile
