# IGCSE Physics Paper-1: Specimen Questions with Answers 15 - 17 of 149

## Question 15

### Question

MCQ▾Draw graph between extension and load if a spring is suspended from a stand

### Choices

Choice (4) | |
---|---|

a. | |

b. | |

c. | |

d. |

### Answer

d.### Explanation

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 16

### Question

MCQ▾When stick is put in water it generates 3 waves in 2 seconds. What can be said?

### Choices

Choice (4) | |
---|---|

a. | The frequency of the waves is 3 Hz. |

b. | Each circle represents a wave front. |

c. | Distance X is the amplitude of the waves. |

d. | Distance Y is the wavelength of the waves. |

### Answer

b.### Explanation

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.

## Question 17

### Question

MCQ▾Find how much is this cylinder empty?

### Choices

Choice (4) | |
---|---|

a. | 40 |

b. | 25 |

c. | 64 |

d. | 36 |

### Answer

d.### Explanation

Here in above figure we show that the cylinder contains water up to point 64.

And capacity of cylinder is 100 ml

Therefore volume of empty cylinder is,
