    Do alt medders understand physics?

    Apart from the worst challenge ever. Which should really have gone "to show how dangerous real medicine is let's all take an overdose and see what happens". We get some weird physics as well. "at the level of its subatomic particles and so-called "orbiting electrons" which aren't even orbiting...

    Cheating on a physics quiz?

    Long story short. I copied my friends quiz to only realize we had different quizzes. Should I leave it alone or tell the proff cheated. I think she'll figure it out on her own though. I'm a first year university student

    Physics Smoking tobacco is bad for your circulatory health.?

    In an attempt to maintain the blood's capacity to deliver oxygen, the body increases its red blood cell production, and this increases the viscosity of the blood. In addition, nicotine from tobacco causes arteries to constrict. For a nonsmoker, with blood viscosity of , normal blood flow...

    Physics question- vectors and boats?

    A boat is pointed straight across a river (east) and is moving at a speed of .55m/s relative to the water. The current of the river is south at .30m/s. How long does it take the boat to cross the river if the river is 65m wide? Can someone explain to me how to solve this problem? Thanks in advance.

    Center of Mass: Dog and Boat physics question?

    A 3.5 kg dog stands on an 15 kg flatboat and is 6.1 m from the shore. He walks 2.6 m on the boat toward shore and then stops. Assuming there is no friction between the boat and the water, find how far the dog is then from the shore? Thank you so much!! I would just love the equations/steps to...

    Quantum physics - time travel and consciousness.?

    As we all know light takes time to travel through space; for example it takes around 8 minutes for light to reach us from the Sun. In other words, we are looking into the past right? So considering that time exists individually for each and one of us (regarding Einstein's theory and how...

    Which statement best characterizes the relationship between physics and chemistry?

    Both are branches of physical science and researchers in one often use principles from the other. Physics is the fundamental science and must be mastered before one is ready to study chemistry. Chemistry studies only things on Earth, while physics expands to study everything in the universe.
