Answer:
0.5504
Explanation:
We can use Bay's theorem to solve this question
P( No physics career/fail) = P(No Physics career and fail)/P(Fail)
= P( Fail/ No physics career)×P( no physics career)/P( fail)
=
=0.5504
The answer is false hope this helps
To solve this problem it is necessary to apply the concepts related to destructive interference.
The concept refers to an overlap of two or more waves of identical or similar frequency that, when interfering, creates a new pattern of waves of lower intensity
By definition destructive interference is given by

Where,

n=integer (1,2,3,4,5,6...etc)
t = thickness
M= Index of refrqaction
For minimum thickness to satisfy this condition n will be minimum there,
n=0
Therefore

Solving to find M,



Therefore the correct answer is B. 1.38
Answer:
Explanation:
in physics, the change in direction of a wave passing from one medium to another caused by its change in speed. For example, waves in deep water travel faster than in shallow.from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction in other words it can be all of them or i can narrow it down some more it can have a change in dirction when light enters into a traveling point for example after moving through air it passes through a prism called compare reflection
Answer: 3 m/s
Explanation:
The average velocity is simply the change in displacement over the specified time interval. I’m this case, we have a total of four intervals,which represent 4 seconds. Dividing 12 m by 4s gives us 3 m/s
