.An 850 turn solenoid with a diameter of 7.0cm is 21 cm long with 42A of current.A long straight wire cuts through the center of

the solenoid, along a diameter.This wire carries a 22A current upward.What is the force on this wire assuming the solenoid's field points due east

Answer:

The answer is that there is no magnetic force on the wire. The force on a wire is the cross product of the current thru it and the magnetic field it is in. In your case, both are parallel and the cross product is therefore zero.

Explanation:

F = (n x i)2 x magnetic constant x a / (2 x g2)

Where,

F = Force, i = Current, g = Length of the gap between the solenoid and a piece of metal, a = Area n = Number of turns, Magnetic constant = 4 x PI x 10-7.

Beryllium has a charge of 2, and bromine has a charge of –1. which is the best name for the ionic bond that forms between them?
Otrada [13]

The best name for the ionic bond that forms between them is Beryllium Bromide.

We have been provided with data,

Beryllium charge, q = 2

Bromine charge, q = -1

As we know the valance electron of Be is +2  and the valance electron of bromine is -1. Since one is metallic and the other is non-metallic.

Now, when they combine they exchange valance electron, and bromine change into bromide so they form Beryllium Bromide.

So, the best name for the ionic bond that forms between them is Beryllium Bromide.
