CIE Physics Paper-1: Specimen Questions 47 - 49 of 109
Question number: 47
How we find temperature?
a balance and a ruler
a force meter
micrometer screw gauge
A balance and a ruler is used to measure mass and length respectively.
Force meter is used to measure force. And screw gauge used to measure small length in range of micro
Therefore Thermometer is used to measure the temperature.
Question number: 48
Which switches must be closed to light both lamps based on the circuit diagram?
2 and 3
1, 2 and 3
1 and 3
1 and 2
Here for two bulbs and three switches are connected as shown in figure. For lighting the bulb circuit should be closed for both the bulb. Therefore from figure switch 1 is connected to 1st bulb so it must be closed and switch 3 is connected to 2nd bulb so it also must be closed for passing the current through both the bulbs.
Question number: 49
Speed-time graph at constant speed for 2 objects is given. Which particle traveled higher distance in first 3 sec?
|d.||Question does not provide sufficient data or is vague|
For Object 1:
Here in given figure we show that an object 1 moving at constant speed 2 m/s.
Here we want to find the distance traveled by the object in first 3 sec. Therefore from formula of speed,
