Suppose an electrical wire is replaced with one having every linear dimension doubled (i. e., the length and radius have twice their original values). How is the resistance of the wire affected?

a. The wire has the same resistance as before.
b. The wire has more resistance than before.
c. The wire has less resistance than before.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

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.
