    (distance)(speed of light)^2 = speed of time with units

    Sorry, I think I made a thread in the wrong section before. I was wondering if anyone thought time could have a speed? If so, what would be its dimensions? I encountered someone who claimed that (distance)(speed of light)^2 = speed of time with units, that would be m^3/s^2 = speed of time...

    Work and coefficient of friction

    If you calculate the coefficient of friction that is when it will be its biggest. When you do this, the answer is .16. Therefore, .2 is wrong... It is impossible for it to be .2

    Work and coefficient of friction

    Read the entire thread. This question is out of the textbook, but my teacher says that there is an error with the coefficient of friction (which the book claims to be .2). It is obvious that there is an error with the coefficient of friction, but I just don't know how to calculate it. The reason...

    Work and coefficient of friction

    It doesn't tell you the acceleration. My teacher challenges that you can still find the coefficient of friction. Knowns: applied force; dimensions of triangle; force of gravity component

    Work and coefficient of friction

    I have already stated previously what are givens in the question. There is a box being pushed up an inclined plane by an applied force that is parallel to the horizontal. We are also given the box's mass and the dimensions of the triangle.

    Work and coefficient of friction

    Perhaps my teacher is wrong and there is nothing wrong with this question.

    Work and coefficient of friction

    A worker pushes a crate weighing 93N up an inclined plane, pushing horizontally parallel to the ground. It then has a digram giving the dimensions of the inclined plane so that an angle can be calculated and work can too. c) THe coefficient of friction is .2. How much work is done by friction...

    Work and coefficient of friction

    Homework Statement This is in my work unit. Can someone lead me in the direction of finding the value of the coefficient of friction? What we have is a box being pushed up an incline plane. There is an applied force parallel to the horizontal as well as the force of gravity given. The...

    Equilibrium of reactions - which direction is favored?

    That doesn't make sense with the definition then. Because in my textbook it defines that if the equilibrium constant is greater than one, then the forward reaction is favoured. Couldn't your reverse reaction be proceeding faster while having a equilibrium constant greater than one?

    Equilibrium of reactions - which direction is favored?

    Thanks, so even if the reverse reaction is proceeding more quickly, the forward can be favoured as depicted by the Keq value > 1?

    Equilibrium of reactions - which direction is favored?

    I don't understand what you mean by "excess meaning enough to stop the reaction". I'll try to give you a better example of what I am asking. Say you are given a question and you are told that the equilibrium constant is 4. You are then told to find out if the reaction is in equilibrium, so you...

    Equilibrium of reactions - which direction is favored?

    Homework Statement Is it the same to say the products are favour and the forward reaction is favoured. Or can the reverse reaction be favoured but the products be favoured. For example, the equilibrium constant is >1 so by definition the products are favoured, but if a system has excess...

    Determining Speed of Toy at Top of Loop-the-Loop

    Homework Statement A toy with a mass of 100g is going through a loop-the-loop with a diameter of .5m. How fast must the car be moving at the top of the loop in order to not fall. The Attempt at a Solution At the top of the loop, there is a normal force (Fn) and the force of...

    Tips for Solving Half Angle Identities with Horizontal Shifts

    Homework Statement I'm on the last section of identities entitled half angle identities. This one seems to give me some trouble because I have never encountered one with a horizontal shift in it. Tips? tan 1/2( ß + π/2 ) = ( 1 + sin ß ) / cos ß
