<span>So we want to know what will happen when the fast moving car that is making loud noise that is initially approaching the person, passes the person and starts to move away. So Doppler effect is a phenomenon where when the source of a sound is approaching a person, the person hears the sound as higher than if the source was standing still with respect to the person because the wavelength is getting shorter, and as the source is moving avay from the person the sound is getting deeper because the wavelength is getting longer. So the correct answer is A. </span>
Answer:
Explanation:
a) R = V/I = 0.7/0.022 = 32Ω
b) R = V/I = 0.6/0.005 = 120Ω
c) No...Current change is not linear with voltage change.
The distance of the object from the lens is 3.12 cm.
<h3>What is magnification?</h3>
Magnification is the process of of enlarging an apparent size of an object.
<h3>Object distance</h3>
The object distance is calculated using the following lens formula;
where;
- M is the magnification
- V is the image distance
- U is object distance
Thus, the distance of the object from the lens is 3.12 cm.
