  • Need something explained dealing with velocity?

    I have data and trying to find 2 formulas:

    Data: h=31.6cm, √h = 5.6214, y=11.4cm

    x1=25cm, x2=27cm, x3=27.5, x4=27, x5=27

    With that I need help finding: x(with bar over it, thinks it means avergae)+- σ_x and v=x(bar over it)*√(g/2y)

    In the wording it says acceleration due to gravity is 979.6 cm/sec. Is that g?

    Why is there a +- ? How do I determine which to use?

    Can someone help me out with finding answers to these two formulas, with the data? I have other data but I just need help on this one so I can do the others.

  • 2g iphone data network?

    I have the unlimited data network plan and right now all I can get is wifi. I am in a place that has wifi now but with a password(college campus) and my iphone can not connect. Now since the wifi can not connect isn't there another way to gain internet by the data network that I am paying for? If so how do I access it on my iphone/setup?

  • Just bought iphone, need help with sim card?

    I just bought a used iphone. It came with a sim card but do not think it works because I have no service. But anyway, I have my own at&t sim card from my previous phone and I inserted it in the iphone and all I get now is the emergency call function when my sim is in there. Am I doing something wrong?

  • Using boolean theorems and postulates?

    Need a little help. Have a test tomorrow and looking to study over some things. Help on anyone will help me out. Thanks

    Use Boolean theorems and postulates to simplify the following equations.

    19) F(x,y,z) = x(z' + z)

    20) F(x,y,z) = xy + xy' + x'y'

    21) F(x,y,z) = x'z' + x'y + x'z + xy

    22) F(x,y,z) = (y' + xz)'

    23) F(x,y,z) = xy+x'y' - put in SOP form, might not can simplify.

  • help with c++ classes?

    Here is what is given(the header file):

    #indef SPEED_CALC_H

    #define SPEED_CALC_H

    class speed_calc

    {

    private:

    int precision;

    public:

    to_do(int p);

    double printSpeed(double seconds, double meters);

    void changePrecision(int p);

    }; #endif

    1. wire code that belongs in speed_calc.cpp(calculate speed by distance/time)

    - here is what I have(i dont know this part and I know it is wrong):

    #include "speed_calc.h"

    speed_calc::spped_calc

    {

    p=precision;

    }

    double speed_calc::printSpeed(double seconds, double meters)

    {

    speed=(double) meters/seconds;

    }

    void speed_calc::changePrecision (int p)

    {

    return speed;

    }

    2. draw UML diagram

    -here is what i have(check it for me please):

    speed_calc

    -precision:int

    +speed_calc(p:int);

    +printSpeed(seconds:double,meters:double):double

    +changePrecision(p:int):void

    can someone check this for me.

  • Help on deciding classes?

    For this summer I am taking Interm. Comp. Programming which is full term. I am registered for Differential Equations which is 2nd term (all of july) which means I will not be able to work because of the times. My fall schedule looks like: Data Structures & Anal. of Algorithms, digital devices(w/lab), discrete structures, and physics 2(w/lab..easy)=13 hours. If I plan on dropping Differential equations this summer an adding a prin. of marketing class for my engineering entrepreneurship award I will be able to work. Would it be to tough adding differential equations in the fall with those other classes?

  • long distance router?

    My friend has bought a linksys router (i think wrt54g, it was about $70-80) and he lives beside his parents house which is about 900-1000ft apart with a patch of woods in between. I set up the router in his parents house but I did not think it would reach, which it did not. Anything I can do to get it to reach to his house so he does not have to pay for a separate connection? I read something about a wireless-g expander for linksys. Anything I should consider?

  • c++ client code help...finals tomorrow...refreshing my brain?

    The point class models a point and has the following member functions available for a

    client program to use:

    point();

    void setPoint(int xCoordinate, int yCoordinate);

    void print();

    double distance(Point nextPoint);

    bool isHigher(Point nextPoint);/*returns true if the

    calling object is Higher (has a greater y value)

    than the passed object*/

    1. Given the information above, write a code segment (start inside main with object

    declarations) that will create two points. Get the coordinates for each point from the

    user and store in the objects (an x coordinate and a y coordinate for each). Then

    determine which point is the highest and print it out.
