This problem appeared in the 2014 Physics Higher & Revised Higher. Here is the worked solution.
The solution involves scale diagrams…ugh and of course vector addition.
Hi Physics students! Here is the video of my second Google Hangout.
This movie shows how the radioactive count rate is affected by placing material of certain thicknesses in front of a radioactive source.
Hi Physicists here is the first Google hangout which I gave this morning.
Great to work with talented tech savvy pupils.
Apologies for my calculation error, well spotted physics students.
Sorry for the mix up at the end when I tried to get back from screenshare and a thanks to Martin Cunningham for use of his notes.

Hi Physics lovers. Click the above picture to download the Java simulation of the photoelectric effect.
Click below below to get the experimental sheet.
Photoelectric practical.
Click the picture below to print off a summary of the photoelectric effect.
Try out this simulation exploring out the relationship between the peak voltage of an a.c. source and the d.c. equivalent voltage.
Roll the mouse over the instructions and the think physics button for more information.
The Wheatstone Bridge is used to find the value of an unknown resistor.
When there is no p.d. across the bridge the we say the Wheatstone Bridge is balanced.
If the value of resistance in the decade box is changed then it follows there is a direct proportional change in the current that will flow across the bridge.
Provided the resistance is not changed too much away from the balance point then it can be written
