explain why holes are made in hanging banners and hoardings

 listen holes are made in hanging banners and hoardings so that air cross the banner without any lose to banner. if these holes are not used in banners and hoardings then due to the pessure of air the banner will fall down.

  1. rapid communication of warning to the government agencies, the ports, fisherman, ships and to the general public
  2. we should not ignore the warning issues by the meteorological department through TV, radio, newspaper.
  3.   avoid driving on roads through standing water ad floods may damaged the roads
  4. construction of cyclone shelter in the cyclone prone areas, and administrative  arrangement for moving people fast to safer place
  5. we should make necessary arrangement to shift the essential household goods domestic animal and vehicles  to safer places

holes are used made in handing because the high speed wind may pass through them without damaging them and bring it down with its huge force and pressure

Holes are made in hanging banners and hoarding so that if  strong winds blow they may not tear and the pressure on the board decreases as air passes from the holes.

so that because of air pressure they are not blown away

Holes are made in hanging banners and hoardings in order to tackle the air pressure. The air get passed through these holes made on the hoardings or banners and thus reduces the pressure of air on them. Therefore, the hoardings do not get blown away or torned due to air pressure

THE HOLES ARE MADE IN THE HOARDINGS AND BANNERS TO DECREASE THE AIR PRESSURE BEHIND THE BANNER. IF THE HOLES WILL NOT BE MADE THE BANNER AND HOARDINGS WILL FALL DOWN.

Holes are made in hanging banners and hoaldings because presence of holes let the air pass through them. As a result they experience less pressure and they remain protected

banners will be destroyed if holes are dade in banners

If no holes are made in banners and hoardings then they will be taken away with the air hence they will be damaged. Holes are made to make a passage for air to move

Air exerts pressure.due to this banners are torn when wind is blowing fast.holes make the wind to pass through it and do not become loose or fall down.

Holes are made on hoardings because, it will reduce the air pressure exerted on it.

Simple Answer
To reduce the air pressure
 
  • 0
Air exerts pressure.wind blowing in high speed may break or displace many things.If holes are made in hanging banners and hoardings,then air can pass through these holes,which reduced the air pressure exerted on the hanging banners or hoardings.

AIR EXERTS PRESSURE. DUE TO THIS PRESSURE THE BANNERS AND HOARDINGS TORN AND FLUTTER WHEN WIND IS BLOWING FAST. HOLES ARE MADE IN BANNERS AND HOARDINGS SO THAT WIND PASSES THROUGH THE HOLES AND THEY DO NOT BECOME LOOSE AND FELL DOWN.

.(i) Balloons and balls can be used only when they are inflated with air. When balloon is overfilled with air it bursts due to excessive air pressure.
(ii) Compressed air is used in the brake system for stopping trains.

Air exerts pressure. Due to this pressure banners and hoarding flutter and torn when wind is blowing fast. Holes are made in banners and hoardings so that wind passes through the holes and they do not become loose and fall down.

Air exerts pressure. Wind blowing in high speed may break or displace many things. If holes are made in hanging banners and hoardings, then air can pass through these holes, which reduces the air pressure exerted on the banners and hoardings. That is why holes are made in hanging banners and hoardings.

So that a air presure change dosnt occur
  • 2
So that air pressure cannot tear them

holes are made so that the banners dont fall down because of the pressure of air

The holes are made in hanging banners and hoardings so that winds could easily pass through them preventing tearing of banners and hoardings

Because it can not be tear due to air pressure.

Holes are made in hanging banners ,because air has pressure so the air can easily pass through the holes and holes are also made for banners and holding they help them to stand straight.

Wind blow in very high speed which break and displaced many thing that is why there are holes in banner and hoarding to pass the air by the whole 
and to reduce the air pressure exert on the hanging banner & hoarding

To pass wind

hi,
     Air exerts pressure. The pressure may cause damage to the banners. If we make holes in the banners the air will move out through the holes. Thus the banner remains without any damage.

Holes are made in banners so that the air passes through it. When holes are not made due to high pressure it falls

Holes are made to tackle the air pressure and the air can go through these holes so that they do not get blown

Answer:?Holes are made?in hanging?banners and hoardings?to allow air to pass through them as a result of which there will be less pressure of air on the?banners?or?hoardings. Unless it is done, these may be uprooted or distorted due to the pressure of the air.
