That depends on the roof material. Metal can be as low a 1/12. Fibergglass shingles should be at least 3/12.
While sand is the most recommended way to go, you can also use grade-pitch, old mortar, or gravel. Sand is preferred by most because it is the easiest to keep level.
It depends on your climate and what the patio cover is made of.
3 inch per foot is usually the lowest pitch for shingles. For only 1/4 inch slope, rolled roofing should be used.
When you move towards a speaker, the pitch of the sound you hear increases. This is because the frequency of the sound waves that are reaching your ears becomes higher as you get closer to the source, resulting in a higher perceived pitch.
The change in pitch of a sound when it moves towards you is known as Doppler effect. When a sound source moves towards you, the waves bunch up, causing a higher frequency and therefore a higher pitch. Conversely, when the source moves away, the waves spread out, resulting in a lower frequency and pitch.
If the source is moving towards you, the pitch of the sound will increase. This is due to the Doppler effect, where the frequency of the sound waves increases as the source moves closer, causing a higher pitch to be perceived.
yes
As a sound source moves towards a listener, the pitch of the sound increases. This is because the sound waves become compressed and the frequency of the waves perceived by the listener is higher, leading to a higher pitch.
You start beat towards the edge of the drum.
If it is a free floating slab, not tied to the house, you could probably have it mud jacked on the low side depending on what is beside it,
When a sound source moves towards you, the pitch will increase (higher frequency) due to a Doppler shift. Conversely, when a sound source moves away from you, the pitch will decrease (lower frequency). This phenomenon is commonly experienced in everyday situations, such as when a vehicle passes by.
