    Discontinuous/Continuous Functions

    Sin(x) goes between 1 and -1 and it oscillates to infinity and negative infinity. I ended up thinking that as the limit approaches 1 from the left side, (x-1)^2 becomes 0 and sin(1/(x-1)) becomes sin(-infinity), so it will be 0 * a number between 1 and -1, and that results in a 0. Is this...

    Discontinuous/Continuous Functions

    Homework Statement Is the function continuous at x=1? f(x) = When x is less than 1: (x-1)^2sin(\frac{1}{x-1}) When x is greater or equal to 1: xsin(πx) Homework Equations None The Attempt at a Solution The answer is yes, don't know how to show that, this isn't homework just studying for...

    Drawing a Lewis Dot Structure for Octathiocane (S8)

    - It is a straight chain. - One end has a 1- formal charge, the other has a 0 formal charge. (Net charge=0) - Sulfur can change lone pairs to bonds. You should be able to figure it out with this, if not let me know. :D

    Projectile Motion, only given horizontal distance

    Are you sure 85.8m is all you're given? There will be many answers if you only have 85.8m as the distance because the magnitude of the initial velocity will be dependent on the angle. In this case, I'd first ask your teacher and if not, just choose a random angle 90>x>0 (most likely 45 degrees...

    What are the air speeds in a Venturi meter with varying tube diameters?

    Nvm, I am right, I don't think I've made any mistakes.

    What are the air speeds in a Venturi meter with varying tube diameters?

    I think this is the correct answer, I was plugging in everything at once on my calculator and I might have been doing something wrong so I was getting a lot of different answers. But I'd still like this to be checked. :) Edit: If the change in height was 2.66mm, would v1 and v2 be: v1...

    What are the air speeds in a Venturi meter with varying tube diameters?

    Homework Statement Air is blown through a horizontal Venturi tube. The diameters of the narrow and wider sections of the tube are 1.0 cm and 3.0 cm respectively, and the height h of the mercury column is measured to be 1.00 mm. What are the air speeds in the wider and the narrower sections of...

    Correct Distance of 28.856m between 2 Points at 350°C

    Oh, forget what I said about the formula thing, I did it two different ways and ended up countering what I said with "making 28.85 the original length". Anyways at a lower temperature the distance shrinks. So the count is higher? I think you are confusing the question a bit. You're not actually...

    Correct Distance of 28.856m between 2 Points at 350°C

    "A steel ruler is correct at 180c. when the temperature was 350c a distance of 28.85 m was measured between 2 points. what is the correct distance" LOGIC TEST :biggrin:! Does steel expand or contract when it gets hotter? Should your answer be larger or smaller than the distance given? I...

    How to compute for Pressure without the acceleration on the Force?

    Well I still think the acceleration wouldn't change. I think it would just be 51.5kg*9.81m/s^2 for the force because the sensor can't detect acceleration, only force. Like if I gave you the equation a*b = 100 and asked you what is a and b? Well there is a ton of possibilities, it could be...

    How to compute for Pressure without the acceleration on the Force?

    "I have an Area which is 2.5 square inch now,the problem is what is the applied force. Since I have a change of rate of the weight which 51.5 kgs from 50kgs. Can I consider this as the Force as 51.5kg/s/s." No, just look at your units for the next part if this was the case. You make force...
