question: if y is proportional to x, and that y=6 when x=12, (A)express y in terms of x, (B)and find to value of x when y=12. answer: (A) x=y/3 (B) x=4 is what i did correct? i would appreciate your help!
okay so this is what i did to find the work done by overcoming friction: Ff = .9 N d = .91 m (Ff x d = Wf --> .9 x .91 = .82 J) hmm okay so how would you find the work done by friction using that calculation that you just said (change in total energy = work done by friction...
One way that I found was knowing the force overcoming friction (Ff). so the equation to fin dthe work would be Wf = Ff * d.. as you said above (force*distance). But what other calculation would you use to find the wasted work without knowing the friction force?
There are two ways to find how much work is done voercoming friction. One method entails knowing the force overcoming friction. What other calculation could be done to find this wasted work?
C) Water may evaporate rapidly
i have to decide which one is more polar by using an arrow. 1. N-H 2. O-F 3.C-O Look up the electronegativity on a chart and take the difference between the two elements. The larger the difference the more polar.
How do I solve this? On my assignment it says find the area inside the square, but outside the circle, given that the radius of the circle is 2 ft. Use 3.14 for ^ I have a picture of a square with a circle in the square, with a base 6 ft. and height 6 ft. Here are the choices ...
I just do not understand ANYTHING about multiplying/dividing/adding/subtracting significant figures! For example, the problem is: Solve the following to the correct number of significant figures: (5.039)(0.0074) What am I supposed to do? Just multiply the numbers? What does th...
