A U-shaped wire of mass has its ends immersed in two jars of mercury, which are separated by a distance . The wire is in uniform magnetic field perpendicular to the plane of the wire. A very fast current pulse is passed through the wire and in response the wire jumps upward a height . How large was the charge which passed through the wire? Use . (You may want to use the results of (Part a).) You may ignore the effect of the gravitational field while the current pulse runs through the wi

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

scientific laws are the result of testing theories and proving them to be facts.

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
