Physics - ICS Part 1 Physics Chapter 1 Short Questions Test

Question # 1

How can you assess the uncertainty in the average value of many measurements?

Ans 1: To assess the uncertainty, we find the deviation of each measured value from the average value. The mean deviation is the uncertainty in the average value.

Question # 1

What dose the word "micro" signify in the words "micro wave oven ?

Ans 1: Micro means very small. Micro waves have the shortest wavelength of all the shortest wavelengths of all the radio waves, therefore, these are known as microwaves. Now like all electromagnetic waves the microwaves produces heating effect when their energy is absorbed. It is because, due to shorter wave length the micro waves posses high frequency and maximum energy.

Question # 1

Differentiate between the precision and accuracy.

Ans 1: Precision: A measurement which has less absolute uncertainty is called precise measurement. The precision of a measurement is determined by the instrument being used.Absolute uncertainty , in effect, is equal to the least count of measuring instrument.
Accuracy: is the one which has less fractional or percentage error. Accuracy measures,how close a measured value is to the actual value.
