CIE Physics Paper-1: Specimen Questions 33 - 34 of 109
Question number: 33
If we cut cotton at two point (indicated by blue line), then length of part1, part 2 and part 3 of cotton are,
24.6cm, 15.6 cm, 2.5 cm
1.6cm, 7.5cm, 4.1 cm
3.4cm, 13.2cm, 4.1 cm
1.2cm, 2.6cm, 3.9 cm
Here we show that cotton on the scale at starting point of rural is 2.4 cm and end point of rural is 15.6cm.
There are two cut on the cotton
So there are total three part of cotton
Then length of part1 is,
Length of part 2 is,
Length of part 3 is,
Question number: 34
Find average speed of molecules in 2 boxes if they are filled with air and one is on heater 1 and the other is on heater 2.
Box X – Slow, Box Y – Fast
Box X – Fast, Box Y – Slow
Box X – Zero, Box Y – Fast
Box X – Fast, Box Y – Zero
Here box X is on heater1 and the box Y is on heater2.
Then molecule in box X is moving fast then Y. Because on heater due to heat the molecules move fast but heater 1 has more power than heater 2. Therefore molecules in X is move faster
