Ruler measure the length of cotton

Ruler measure the length of cotton

In figure length of cotton is measured by the ruler. At both blue arrow cotton will cut.

Choices

Choice (4) Response
a.

24.6cm, 15.6 cm, 2.5 cm

b.

1.6cm, 7.5cm, 4.1 cm

c.

3.4cm, 13.2cm, 4.1 cm

d.

1.2cm, 2.6cm, 3.9 cm

Answer

b.

Explanation

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,

L1=42.4

L2=1.6cm

Length of part 2 is,

L2=11.54

L27.5cm

Length of part 3 is,

L3=15.611.5

c.

Box X – Zero, Box Y – Fast

d.

Box X – Fast, Box Y – Zero

Answer

b.

Explanation

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
