Answer:
The statement "If a positively charged rod is brought close to a positively charged object, the two objects will repel
" applies to electric charges.
Explanation:
There are only two types of electric charges. Both having own magnitude but different charge.
1. Positive charge
2. Negative charge
Like charges repel each other and opposite charges always attract each other.
When a positively charged rod is brought close to a positively charged object, the rod and the object will repel.

as we know that velocity= displacement/change in time
hence velocity here is= 11-3/12-0
=8/12
=2/3
=0.667m/s
hopefully i am right
When a steadily flowing gas flows from a larger diameter pipe to a smaller diameter pipe the pressure does not decrease, it increases, do to the smaller volume.
Answer:
Combined speed, V = 2 m/s
Explanation:
Given that,
Mass of object 1, m = 5 kg
Speed of object 1, u = 4 m/s (due right)
Mass of object 2, m' = 2 kg
Speed of object 2, u' = -3 m/s (due left)
<em>Let V is the speed of the objects after the collision. Here, both objects stick to each other. Therefore, the momentum remains conserved. So,</em>
So, the combined speed of the masses will be 2 m/s.
