Explanation:
Speed of Bob, v = 0.967 c
At the exact instant he passes Alice, she fires a very short laser pulse in the same direction Bob is moving.
(a) We need to find the distance measured by Alice between Bob and the laser pulse. It is given by :
(b) Distance measured by Bob between himself and the laser pulse is given by :
Hence, this is the required solution.
The refractive index of a medium is independent of (not related to) the angles of incidence or refraction. It's just a property of the medium. <em>(D)</em>
Answer:
Explanation:
Given that
I = a + b t
b = 14 A/s , h= 1 cm , w= 15 cm , L= 1.05 m
The magnitude of induced emf is given as follows
I = a + b t
Now by putting the values in the above equation we get
Thus the induce emf will be
Option D is correct. P wave can travel through liquids. P stand for the primary of pressure wave.
<h3>What is wave?</h3>
A wave is a phenomenon that flows across a material medium without leaving any lasting mark. Mechanical or electromagnetic waves can be used to classify it. Transverse and longitudinal are the two main forms.
P waves are sometimes known as primary waves or pressure waves. The earliest waves of an earthquake are known as P waves.
P waves may pass through any medium, including liquids, gases, and solids. P waves can't move particles up and down or side to side.
P wave can travel through liquids. P stand for the primary of pressure wave.
Hence, option D is correct
