The answer is <span>A. A warm and humid day with a wind moving in the same direction as the sound.
Sound waves travel through a medium such as solid, liquid, or gas. It travels faster when the molecules of its medium are closer together. This is the reason why it travels the slowest through dry air. When air is wet or humid, sound can travel faster because sound travels faster through water.
When sound waves pass through air, the most important factor that affects it is temperature. The higher the temperature, the faster the molecules vibrate. This allows sound waves to travel faster.</span>
Inertia IS always present. Inertia is NOT the force that causes objects to continue moving in circles, that is centripetal force. Centripetal force is NOT always present. Centripetal force DOES pull objects toward the center of a circle. <span> Inertia and centripetal force DOES cause circular motion. Thank you and eat sand fren ;)</span>
Answer:
Part a)
F = 0.051 N
Part b)
Both spheres will follow Newton's III law of action reaction force so both sphere will have same force of equal magnitude.
Explanation:
Part a)
Electrostatic force between two charged spherical balls is given as

here we will have

here the distance between the center of two balls is given as

now we will have


Part b)
Both spheres will follow Newton's III law of action reaction force so both sphere will have same force of equal magnitude.
