Two rigid rods are oriented parallel to each other and to the ground. The rods carry the same current in the same direction. The
IRISSAK [1]

To develop this problem we will apply the concepts related to the Electromagnetic Force. The magnetic force can be defined as the product between the free space constant, the current (of each cable) and the length of these, on the perimeter of the cross section, in this case circular. Mathematically it can be expressed as,

F= \frac{\mu_0}{2\pi} \frac{I^2L}{d}

Here,

\mu_0 = Permeability free space

I = Current

L = Length

d= Distance between them

Our values are,

L = 0.67m

m = 0.082kg

d = 7.4*10^{-3}m

I = \text{Current through each of the wires}

Rearranging the previous equation to find the current,

\frac{mg}{L} = 2*10^{-7} (\frac{I^2}{d})

I = \sqrt{\frac{mgd}{(2*10^{-7})L}}

I = \sqrt{\frac{(0.082)(9.8)(7.4*10^{-3})}{(2*10^{-7})(0.67)}}

I = \sqrt{44377.9}

I = 210.66A

Therefore the current in the rods is 210.6A

Help please if you know this I will appreciate it thank you
aev [14]
The independent variable is the one thing that changes in the experiment, the dependent is what you are measuring, and controlled is all the things you keep the same and never change. So for the first one I=different tire trends (change it each time), D=breaking distance (what you are measuring) and C=use the same car, same brand of tires, same brand of brakes, run cars on same surface etc..
Hope this helps!

show that if a particle is in a stationary state at a given time it will always remain in a stationary state.
Lena [83]

That statement is impossible to show, demonstrate, or prove.

A big part of the reason for the inability to show it is that the statement is ... prima facie, pro bono, and habeus corpus ... wrong, and as false as the day is long.

Although I am certainly far from what you might call a 'particle', I think I can show, using myself, that the statement is false:

As we speak, I am sitting, <u><em>in a stationary state</em></u>, before my computer.  It is my intention, and I fully believe it will come to pass, that in a few seconds, my fingers may move to operate one of the letter keys, or my hand may reach out to snag my coffee cup, or my entire being may arise from my place and go into the kitchen for a bowl of oatmeal.  At the INSTANT that any of these events takes place, the statement will have been proven false.
