Faahfaahinta casharka

Natiijada casharka

I can describe how the pressure changes at different depths underwater and heights in the atmosphere.

Muuji qoraalka

The bigger the surface area of a boat’s hull, the bigger the upthrust on it can be. Pressure in liquid increases with depth because there is more liquid pushing down. Pressure in the atmosphere reduces with height because there is less air pushing down.

Imtixaannada

1. Waa kee mid ka mid ah kuwan soo socda ee kordhin doona cadaadiska (pressure) uu mindi ku sameeyo marka lagu goynayo xadhig?
- Jawaabta saxda ah:kordhinta xoogga (force) la isticmaalayo
- yaraynta xoogga la isticmaalayo
- afeynta mindida si loo yareeyo bedka (area) taabashada
- mindida la dhigista si loo kordhiyo bedka taabashada
2. Mid ka mid ah kuwan ayaa ah isla'egta saxda ah ee lagu xisaabiyo cadaadiska (pressure)?
- $$ pressure = {force \times area}$$
- Jawaabta saxda ah:$$ pressure = {force \over area}$$
- $$ pressure = {force + area}$$
- $$ pressure = {force - area}$$
3. Sanduuq culeyskiisu yahay 30 N ayaa taabanaya dhulka meel dusha ah oo ah 0.5 m². Waa maxay cadaadiska (pressure) uu sanduuqu ku sameeyo dhulka?
- 29.5 N/m²
- 30 N/m²
- 30.5/m²
- Jawaabta saxda ah:60 N/m²
- 120 N/m²
4. Arday gacantiisa oo bedkiisu yahay 60 cm² ayuu ku cadaadiyaa hoos. Cadaadiska uu soo saaro waa 1.2 N/cm². Waa imisa xoog (force) uu ku riixayo hoos?
- 50 N
- 60 N
- 61.2 N
- Jawaabta saxda ah:72 N
5. Mid ka mid ah kuwan soo socda ayaa soo saara cadaadis (pressure) ah hal pascal (1 Pa)?
- xoog (force) ah 1 N oo ku shaqeeya aag (area) ah 1 cm$$^2$$
- xoog ah 1000 N oo ku shaqeeya aag ah 1 m$$^2$$
- Jawaabta saxda ah:xoog ah 1 N oo ku shaqeeya aag ah 1 m$$^2$$
- xoog ah 10 000 N oo ku shaqeeya aag ah 10 000 cm$$^2$$
- xoog ah 1 N oo ku shaqeeya aag ah 10 000 cm$$^2$$

1. Mid ka mid ah kuwan ayaa kordhin doona culeyska ugu badan ee rafti (raft) uu qaadi karo ka hor inta uusan bilaabin inuu quusin?
- kordhinta culeyska raftiga
- yaraynta bedka (surface area) ee raftiga
- Jawaabta saxda ah:kordhinta bedka (surface area) ee raftiga
- samaynta raftiga ka sameeyaan walxo culus (denser)
2. Raf miisaankiisu yahay 2000 N, bedkiisu (surface area) yahay 4.0 m², wuxuu dusha biyaha ku sabbeynayaa. Waa maxay cadaadiska (pressure) ay biyuhu saarayaan rafka?
- 0.002 N/m²
- Jawaabta saxda ah:500 N/m²
- 1996 N/m²
- 2004 N/m²
- 8000 N/m²
3. Shark baa ku sii socota qoto dheer oo badda ah. Kee ka mid ah kuwan soo socda ayaa sax ah?
- cadaadiska (pressure) ayaa hoos u dhacaya marka qoto dheer la gaaro
- Jawaabta saxda ah:cadaadiska ayaa kordhaya marka qoto dheer la gaaro
- cadaadiska wuxuu ka shaqeeyaa dhinacyo kasta
- cadaadiska wuxuu ka shaqeeyaa kaliya kor
4. Saaxiibkiis, saaxir ayaa galaas ku buuxiyay biyo, markaasna waraaq ka sameysan kaar ayuu saarayaa gudaha. Dabadeedna galaaska iyo kaarka ayuu si taxaddar leh u rogaa, laakiin biyuhu ma daataan. Waa maxay sharaxaadka ugu fiican ee arrintan?
- Biyuhu waxay noqdeen kuwo aan culeys lahayn maadaama kaarku uu xannibayo xoogagga cufisjiidadka.
- Cadaadiska biyaha ee hoos u riixaya waa eber maadaama kaarku uu leeyahay aag aad u yar.
- Jawaabta saxda ah:Cadaadiska hawada ee kaarka hoostiisa ayaa soo saaraya xoog ka weyn culeyska biyaha.
- Kaarku waa mid aan biyaha dhex gelin, sidaas darteed biyuhu ma baxsan karaan.
