Question
What is the magnification produced by a rear view mirror fitted in vehicles?

Answer

The convex mirror forms virtual, erect and diminished image of the object and rearview mirror also form some type of image.
Therefore, magnification (m) produced by a rear view mirror fitted in vehicles is less than one i.e., m < 1.
Magnification (m) $=\frac{\text{Image height}}{\text{Objects height}}$

In an experiment to study the relation between the potential difference across a resistor and the current through it, a student recorded the following observations:
Potential V (volts) 1.0 2.2 3.0 4.0 6.4
Current I (ampere) 0.1 0.2 0.6 0.4 0.6
On examining the above observations the teacher asked the student to reject one set of readings as the values were out of agreement with the rest. Which one of the above sets of readings can be rejected? Calculate the mean value of resistance of the resistor based on the remaining four sets of readings.
