I have a few questions on magnetic fields: . 1) If two magnetic fields are perpendicular, how do they act? . 2) If the fields are setup as shown in the diagram [see attachment] how do they act? . For #2 I see how it is setup, but I get confused by all the circling ad everything :confused...

A small plastic ball of mass 6.10 10-3 kg and charge +0.150 µC is suspended from an insulating thread and hangs between the plates of a capacitor (see the drawing). The ball is in equilibrium, with the thread making an angle of 30.0° with respect to the vertical. The area of each plate is...

Tried that and got 46.29 But wrong... so what did I do?

i really cannot get these and my grade depends on these :uhh: No clue on #1 But for 2nd I try to find sum of forces and set equal to the weight of the cylinder, but it isn't right...

Forgive my double post o:) . I got the third problem so no help needed there :smile:

That :smile:

Fluids - I wish the answer would "flow" to me I have two problems to do and I seem to suck at fluids...:tongue: . The drawing shows a hydraulic system used with disc brakes. The force F is applied perpendicularly to the brake pedal. The brake pedal rotates about the axis shown in the drawing...

A mercury barometer reads 700.0 mm on the roof of a building and 715 mm on the ground. Assuming a constant value of 1.29 kg/m3 for the density of air, determine the height of the building. . My setup was finding the difference in the pressures for mercury and get 15 mm Hg Then use Hg density...

The equation for work would help explain... :smile:

One question... are the wires attached to the ends of the block, you were not clear on that...

Where do you put your fulcrum?

You lost a square on the .09 on the left side...

Thanks for that... now back to the other parts... :frown:

Conservation of momentum (mv = (M+m)v') will get a linear speed, which can be converted to rotational speed if I am remembering right...:rolleyes:

What is your current curriculum/topic in class?
