Tooth fillings are often made of gold or porcelain because these materials are:

b. nonreactive

That means that they don't corrode or rust and they are resistible to staining.Their thermal conductibility is low.

Explanation:

Porcelain-fused-to-metal crowns. PFM crowns are an approximately esthetic improvement that has been in use for more than 40 years. In one way, they blend the best of both worlds, a crown made of “refined or noble” metal (gold or platinum), which is strong, fits correctly and is bonded/bonded to the tooth.

An 11.0-W energy-efficient fluorescent lightbulb is designed to produce the same illumination as a conventional 40.0-W incandesc

mario62 [17]

Answer:

$Savings = $0.709$

Explanation:

Energy consumed by 11 W energy efficient fluorescent bulb is given as

$E = Power \times time$

now we can say

$E = 11 \times 220h$

$E = 2.42 kWh$

now total cost of the energy used is given as

$Amount = 2.42 \times $0.111$

$Amount = $0.268$

Now for conventional 40 W bulb we can say

$E = Power \times time$

now we can say

$E = 40.0 \times 220h$

$E = 8.8 kWh$

now total cost of the energy used is given as

$Amount = 8.8 \times $0.111$

$Amount = $0.977$

So total money saving is given as

$Savings = $0.977 - $0.268$

$Savings = $0.709$

As a pan is sitting on a stove it begins to heat up. Eventually it may get hot enough that it glows red, meaning it is radiating

saul85 [17]

Answer:
Your answer is B.!

When things in general get hotter, the atoms inside move faster and vise versa with cold.

(for example water); if you put water in a pot on a stove to boil, its gets so hot to where the atoms are moving really fast to get it to look like that.

Please mark brainiest! if this answer is wrong, (which I'm pretty sure it isn't) then pick D. :D
