Answer:
electric flux = 177.625 N-m²/C
Explanation:
given data
angle = 45°
diameter = 4 m
electric field E = 20 N/C
to find out
electric flux
solution
we know electric flux formula that is
electric flux = E × A × cosθ ..............1
here A is area that is
Area = πd²/4 = π(4)²/4 = 12.56 m²
now put all value in equation 1
electric flux = 20 × 12.56 × cos45
electric flux = 177.625 N-m²/C
Answer:
t = 8.3s
Explanation:
V = 100 m/s U = 0 m/s t = ? a = 12 m/s2
V = U + at
100 = 0 + 12 × t = 100 = 12t
12t = 100
t = 100/12 = 25/3
t = 8.3s
Sounds are reflected best when bounced off the flat surfaces.
<h3>What is a sound wave?</h3>
A sound wave is produced when a medium begins to vibrate. When an entity vibrates, a pressure wave is formed, which causes sound.
Since sound waves cannot easily pass through hard surfaces, they bounce off them instead, reflecting back to the source which they first came from.
When sound is reflected off of flat surfaces, it does so most effectively.
Hence the flat surface is the correct answer.
