B The skin of a banana turns from green to yellow...
Answer:
550 nm
Explanation:
The formula for the double-slit diffraction experiment is:
where
y is the distance of the m-th maximum from the central fringe
is the wavelength of the light used
D is the distance of the screen from the slits
d is the separation between the slits
In this problem we have:
is the distance between the slits
is the distance of the screen
We also know that the distance between the 3rd and 5th order maximum is 5.5 mm, which means that:
And we can rewrite this as:
where we used respectively m=3 and m=5. If we know solve for , we find the wavelength:
I believe the answer is Mouse/Herbivore. It was a question in my old lab haha.
Hope this helped!!

Answer:
1. Number of dry cells of 1.5 V required is 40.
2. Number of internal resistance of 1 ohm required is 807
Explanation:
We'll begin by calculating the resistance. This can be obtained as follow:
Power (P) = 60 W
Voltage (V) = 220 V
Resistance (R) =?
P = V²/R
60 = 220² / R
Cross multiply
60 × R = 220²
60 × R = 48400
Divide both side by 60
R = 48400 / 60
R ≈ 807 Ohm
1. Determination of the number of dry cells of 1.5 V required.
Voltage (V) = 220
Dry Cells = 1.5 V
Number of dry cells (n) =?
n = Voltage / Dry cells
n = 60 / 1.5
n = 40
2. Determination of the number of internal resistance of 1 ohm required.
Resistance (R) = 807 Ohm
Internal resistance (r) = 1 ohm
Number of internal resistance (n) =?
n = R/r
n = 807 / 1
n = 807
SUMMARY:
1. Number of dry cells of 1.5 V required is 40.
2. Number of internal resistance of 1 ohm required is 807
Force = mass * acceleration
Here is an equation for force, used to calculate force.
Look at it this way:-
Joules is used to measure force, while mass is measured by kg. Acceleration is measured by m/s/s (meters per second per second, or meters per second squared.)
joules = m/s/s * kg
Which makes everything fit in just right! :D
