Three wires of the same diameter are connected in turn between two points maintained at

a constant potential difference. Their resistivities and lengths are r and L (wire A), 1.2r

and 1.2L (wire B), and 0.9r and L (wire C).

a. How does the rate at which energy is transferred to thermal energy vary with the

resistance of the wire? In other words, does the dU/dt increase with increasing

resistance or does it decrease with increasing resistance? Remember, the potential

across each wire is the same. Explain.

b. Using your answer from part (a), rank the wires according to the rate at which

energy is transferred to thermal energy within them, greatest to least.

step-by-step explanation:

not moving. pos accel,

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.

- 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.
