    Is This Really Mussolini with My Great Grandfather?

    My dad suggested to me that because their collars are black and the presence of daggers it might be an Arditi unit? You can see a dagger in the hand of the man with the arm band. I realized my phone can take much higher quality images than my scanner so I uploaded the shots here. I'm sorry I did...

    Thermal energy question: Final temperature of a solution

    Thank you for the formula and the link. I plugged in the values to both sides of the equation that provided and arrived at 24,442.18074 on both sides. This seems like a great way to check my work when I'm dealing with such questions.

    Is This Really Mussolini with My Great Grandfather?

    Wow, thank you to everyone for really dissecting this. I'll try to do some research if facial recognition could be used on this image. I would love to know more about the unit. I already learned so much from my German/Canadian relatives who passed away but never got to really hear any stories...

    Is This Really Mussolini with My Great Grandfather?

    Thank you for the suggestion and the information! Quora is worth a shot. I was doubtful myself but started to slightly entertain that was him in the photos when i saw some younger images. The jaw line seems like it could be right although the image is quite dark and shady.

    Thermal energy question: Final temperature of a solution

    Hello, and thanks again. I followed that equation and calculated it out to 28.5810306. I was unable to punch it all into my calculator at once unfortunately because I did not know how to define the T and we never spent any time covering that in our class. I'm hoping to to find a good tutorial...

    Thermal energy question: Final temperature of a solution

    Ugh.. I thank you for catching that change to 9.1. I'll redo the calculation following the equation format you provided. Thanks for the input!

    Is This Really Mussolini with My Great Grandfather?

    Just asked my dad, it seems he asked the same question on that forum. Thanks for your response!

    Is This Really Mussolini with My Great Grandfather?

    Hello, I recently received a photograph from my father, that supposedly depicts my great grandfather in a machine gun unit with Mussolini. According to my father, my great grandfather would often tell tales about being a in a unit with Mussolini and that he was "a big mouth". My father later...

    Thermal energy question: Final temperature of a solution

    Hello, thank you for taking the time to read this.. I hope I followed the formatting correctly and this post complies with the expectations of the forum. I solved the equation but my answer seems too low. I tried it again and arrived at the same answer. I also had doubts if it was acceptable...

    Determine the mass of the planet using Newton’s Law of Universal Gravitation

    Hello, and thank you again to anyone who can confirm if I have the right answer or who can give me some suggestions. This question felt like a bit of a surprise because we have not yet covered one where the mass of a planet was missing. Thus, my confidence in my work is low. Part b felt like a...

    Newton's third law problem/kinematics (Airboat problem/no friction)

    Thank you very much for your time. I suppose the lack of friction means this hypothetical airboat can reach some monstrous speeds.

    Newton's third law problem/kinematics (Airboat problem/no friction)

    Thank you very much your time! I first found the force of the air on the boat using the principle of Newton's third law and the fact that no friction is involved. Faction= -Freaction 150 N backwards = -150 N backwards 150 N backwards = 150 N forward I then sought to determine the...
