False. That's why sound cannot be heard in space.
Answer:
D. The objects particles move faster
Answer:
close to the mirrors surface
Explanation:
this is because angle of incidence equals angle of reflection
Answer:
12500 V
Explanation:
The electric field in the gap of a parallel-plate capacitor is uniform, so the following relationship between electric field strength, potential difference and distance can be used:

where
is the potential difference between the plates
E is the electric field strength
d is the distance between the plates
For the capacitor in this problem, we have


Substituting, we find
