Estimated Physics 32 GT??

manyyy are saying mass wouldnt change at all! it would be constant!

i also wrote it decreased!

because increase in room temp means molecules will move quickly thereby producing heat and warm air is less densed so decreased mass of air

options i forgot just remember 2 as only these looked sensible!

what is truue abt thermal radiation

is it infrared
or it needs only vaccum to travel!

radiations can travel in vacuum so a

candle question was c

 

[shoaib672002]

first mcq length was 2.7 cm

 

[shoaib672002]

2nd question speed distance graph was d constant gradient

 

[shoaib672002]

3rd pasta and rice had same weight

2nd question speed distance graph was d constant gradient

Yeep! what was the average speed u got?

 

[shoaib672002]

mirror should be staright (a) so that the ray goes till person on cliff

 

[shoaib672002]

F was latterally inverted so a

 

[shoaib672002]

capacitor question i dont remember

 

[dubi2pro]

Yep mine mathes the same as urs in mcqs!

 

[dubi2pro]

Also what was the angles of incidence u got? i got 42

 

[shoaib672002]

Yeep! what was the average speed u got?

average speed was 1.25 m/s

 

[shoaib672002]

Also what was the angles of incidence u got? i got 42

u just had to draw a reflected ray and label normal and stuff

 

[shoaib672002]

Salmon height 0.81 m

 

[shoaib672002]

Angle of refraction is 22

 

[shoaib672002]

At least like my posts :l

 

[dubi2pro]

Angle of refraction is 22

it was 42.. it said from water to air

so we had to use sin r/ sin i

Hhahahah Fine! -.-
