Find the electric flux passing through the 45° surface of an upright circular cone with a base diameter of 4 m if the electric f
alexgriva [62]

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

How much time is required for a car to reach a speed of 100 m/s if it starts from rest and its average acceleration is 12 m/s2?
gtnhenbr [62]

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 [answer] hard surfaces.
yuradex [85]

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.

To learn more about the sound wave refer to;
