Answer:

Refineries process oil, found in the Earth, and turn it into gasoline to be used by cars.

Explanation:

The first option describes Geothermal energy. Geothermal energy uses the heat of the Earth's crust as a heat source. It is a renewable resource.

Refineries use the oil extracted from the Earth to produce gasoline. This is a non renewable resource as the oil found in the Earth is of finite quantity and is being depleted faster than it is being replenished.

Solar panels use the sunlight to produce electricity. Sunlight is a renewable resource.

Windmill uses the power of moving air to generate electricity. Wind is a renewable resource.

Answer:

You are asked to design a cylindrical steel rod 50.0 cm long, with a circular cross section, that will conduct 170.0 J/s from a furnace at 350.0 ∘C to a container of boiling water under 1 atmosphere.

Explanation:

Given Values:

L = 50 cm = 0.5 m

H = 170 j/s

To find the diameter of the rod, we have to find the area of the rod using the following formula.

Here Tc = 100.0° C

k = 50.2

H = k × A × $\frac{[T_{H -}T_{C} ] }{L}$

Solving for A

A = $\frac{H * L }{k * [ T_{H}- T_{C} ] }$

A = $\frac{170 * 0.5}{50.2 * [ 350 - 100 ]}$

A = $\frac{85}{12550}$ = 6.77 × $10^{-3}$ m²

Now Area of cylinder is :

A = $\frac{\pi }{4}$ d²

solving for d:

d = $\sqrt{\frac{4 * 0.00677 }{\pi } }$

d = 9.28 cm

3. What are some questions that philosophers ask about knowledge?

Mariulka [41]

Hello there,

<span>What are some questions that philosophers ask about knowledge?

I hope I would be understanding your question right. But I believe that on question they could ask is " What part in the human brain could store up all this knowledge that any human can store".

I truly hope this helps.
