Answer:
Speration between the slits
Explanation:
Given that,
Wavelength of light,
It is incident on a double slit produces a second-order maximum at an angle of 25 degree.
The condition for maxima is given as :
d = seperation between the slits
m = order, m = 2
d = 0.00000289
or
So, the seperation between the silts is . Hence, this is the required solution.
Answer:
7.7 km 26°
Explanation:
The total x component is:
x = 2.5 cos(35°) + 5.2 cos(22°) = 6.87
The total y component is:
y = 2.5 sin(35°) + 5.2 sin(22°) = 3.38
The magnitude is:
d = √(x² + y²)
d = 7.7 km
The direction is:
θ = atan(y/x)
θ = 26°
Answer: The mean of the samples is 32.325.
Proportion of the defective unit is =
Explanation:
The point estimate of the mean of the sample:
First calculate the mean of the 40 samples:
The mean of the samples is 32.325.
Defected pieces in the samples whose life span is less than the 26 days = 2
Proportion of the defective unit is =
