CIE Physics Paper-1: Specimen Questions 61 - 63 of 109
Question number: 61
Mercury-in-glass thermometer reaches point X at 0 °C and point Z at 100°C. Find location if temperature is below the ice-point?
Here given that At point x is 0 °C
And at point Z is 100 °C
Now as we know that
The temperature of ice is zero or below zero
Then point below the temperature of ice point is W.
Question number: 62
Which radiations are stopped by a sheet of paper?
Here as we know that
Α-particles are fast moving helium atoms. They have high energy typically in the MeV range, but due to their large mass their range is small and they are stop by just few inches of air, or paper.
Question number: 63
Which statement is correct?
Mass is a force, measured in Newton.
Weight is a force, measured in kilograms.
Mass is a force, measured in kilograms.
Weight is a force, measured in Newton.
Here as we know that the weight of any object means gravitational force between earth and the object.
If the object has more mass then it has more weight. So we can say that Weight is a force therefore we can write unit of it is newton.
