CIE Physics Paper-1: Specimen Questions 14 - 16 of 109
Question number: 14
Find the water level in the diagram below.
Which option is be most suitable for its scale?
Here in above figure we shows that the cylinder contain water up to certain point.
Now it is clearly show in figure that till at point 55 water is filled. Thus one can say that volume of water is 55 mm3.
Question number: 15
Draw graph between extension and load if a spring is suspended from a stand
In above four graph we shows that last graph is right
Because in this graph we clearly see that
As we increase load then expansion of spring take place
We can see that as load is zero then expansion is zero and then increase load then expansion is increase.
Question number: 16
When stick is put in water it generates 3 waves in 2 seconds. What can be said?
Distance X is the amplitude of the waves.
Each circle represents a wave front.
The frequency of the waves is 3 Hz.
Distance Y is the wavelength of the waves.
If stick up and down in water then we get circle. The diameter of circle is different for every up and down. Each up down produce a wave front shape of circle and it propagation in same shape. Similarly in figure all three circles are represented a wave front.
