Answer:
a. The spheres will attract each other.
Explanation:
When two conducting spheres are connected by a conducting wire and a negatively charged rod is brought near it then this will induce opposite (positive) charge at the nearest point on the sphere and by the conservation of charges there will also be equal amount of negative charge on the farthest end of this conducting system this is called induced polarization.
- When the conducting wire which joins them is cut while the charged rod is still in proximity to of one of the metallic sphere then there will be physical separation of the two equal and unlike charges on the spheres which will not get any path to flow back and neutralize.
- Hence the two spheres will experience some amount of electrostatic force between them.
The movement of air flows from high pressure to low pressure
The average speed is 116.66m/s.
Given - The path traced is 14km , time for jogging is 2 hrs=120min
To find the average speed-
- Speed refers to the ease of the movement and degree of mobility as a result of force application.
- Due to this there is involvement of velocity.
- Journey of average speed is the cumulative of distances and time.
- Kinetic theory refers to the Boltzmann constant connecting to the standards of distance traversed.
calculations-
Speed= 14 000 / 120
= 116.66m/s

Answer: 1.5 m/s
Explanation:
9-3/5-1= 6/4= 3/2= 1.5
Used x2-x1/t2-t1 to get average velocity from point b to c
Mph= miles per hour
kph= kilometers per hour
