Apositive rod is placed to the left of sphere a, and the spheres are separated. which best describes the spheres? sphere a is negative and sphere b is positive because protons from sphere a are attracted to the rod and move to sphere b. sphere a is negative and sphere b is positive because electrons from sphere b are attracted to the rod and move to sphere a. sphere a is positive and sphere b is negative because electrons from the rod move to sphere b and protons then move to sphere a. sphere a is positive and sphere b is negative because protons move from sphere b to the rod and also to sphere a.

When a positively charged rod is placed near the sphere A then due to the attraction force of rod all the electrons will come to the nearest surface of  sphere A and due to deficiency of electrons on the far side of sphere B it will get positive charge

This phenomenon of charge separation is know as induction of charge

So sphere A will get negative charge and sphere B will get positive charge on its surface after they got separated

So here correct answer would be

Sphere A is negative and sphere B is positive because electrons from sphere B are attracted to the rod and move to sphere A.

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
