Answer:
See explanation for step by step explanations.
Explanation:
Let X be the mass of a randomly selected resistor
The probability density function is given as
, 80<x<120
=0, otherwise
a) By using the given pdf we have to find the probability of the resistors having resistance less than 90
=
=
=0.0625
the probability of the resistors having resistance less than 90 is 0.0625
Step 2 of 4<
/p>
b) we have to find the mean resistance
Mean=
=
=
=106.67
The mean resistance is 106.67

Potential energy because it has enough energy to do work but non has been done yet.
Answer:
see below
Explanation:
refractive index of a medium is defined as the ratio of the speed of light in vacuum to the speed of light in medium
critical angle of glass is 42 means that if the angle of incidence inside the glass is 42 degrees, then the angle of refraction in the optically less dense medium will be 90 degrees
hope this helps
