Colorful wool is being woven into a scarf in cold, damp Ireland. Wool is used for scarves, sweaters, hats, and gloves because it is a good insulator.
If wool is a good insulator, what substance would be a good conductor?

A) cotton

B) fur

C) metal

D) plastic

C

Explanation:

definition of conductor: “Conductors are materials that permit electrons to flow freely from particle to particle. An object made of a conducting material will permit charge to be transferred across the entire surface of the object.”

“Metals are especially good thermal conductors because they have freely moving electrons that can transfer thermal energy quickly and easily.”

-also the rest are not conductors, they are insulators :)

have a lovely day!

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

denser than mercury would sink in it
