Explanation:
Your reasoning that the shadow is the shortest at mid-day is spot-on!
The wording of the question is the key to the answer. It says that the measurements were made in Summer. So this means that British Summer Time (BST) is being applied. BST is one hour ahead of Greenwich Mean Time and so what looks like 1pm is really 12 noon.
The safest sort of answer is to say that the shadow is shortest when the sun is at its highest point, and in this particular question that is at 1 pm because it is BST.
Answer:
Energy will be equal to 
Frequency will be equal to 
Explanation:
We have given frequency of the radar f = 10 GHz 
Speed of light 
Plank's constant 
So energy 
,here h is plank's constant and 
is frequency
So energy 
In second case we have given wavelength = 25 cm = 0.25 m
Wavelength is equal to 
So 
So frequency will be equal to
I think the answer is Allele am not so sure of it and sorry if my answer is wrong or didn’t help okay

Anode
Explanation:
The anode in the gas discharge tube used by Thomson in his experiment was the positively charged electrode.
Using the gas discharge tube, Thomson made the remarkable discovery of cathode rays.
The rays moves from the negatively charged cathode to the positively charged anode. This indicated that the rays carry positive charges.
Some parts of the tube are:
- Cathode - negatively charged electrode
- Power source
- Gas at low pressure
- Outlet to vacuum pump
