The answer is A
energy is never gained or lost in a collision ITS JUST TRANSFERRED
They put gaps between the particles to slow down conduction
They make the material thicker so energy has to travel a further distance.
Answer:
Capacitance is the ratio of the charge to the potential difference. How is the charge stored on a capacitor related to the capacitance of the capacitor and the potential difference across the capacitor? The charge equals the product of the capacitance and the potential difference.

Answer:
light waves can travel in vacuum but sound waves require a medium to travel
also light waves are electromagnetic waves while sound waves are mechanical, light waves are transverse waves while sound waves are longitudinal waves
Answer: A is correct
It is showing the direction that protons move in, making the sphere negative
Explanation:
From the figure, since the charges on the rod are completely positive, it shows that the protons are transferring from the sphere to the rod leaving the rod negatively charged.
Therefore, It is showing the direction that protons move in, making the sphere negative.
