Remember that a controlled variable is a variable that stays the same thoughout the experiment.

it wouldn't be a. because two different wires were used

the final length of the wax would be your dependent variable, so it wouldn't be c.

the thermal conductivity is the independent variable so it isn't d.

the original length of the wax was the same for both.

So B is your answer.

Where would you expect to find the greatest use of geothermal energy in the US and why?
Vanyuwa [196]

Answer:

Geothermal reservoirs are naturally occurring areas of hydrothermal resources. These reservoirs are deep underground and are largely undetectable above ground. Geothermal energy finds its way to the earth's surface in three ways:

Volcanoes and fumaroles (holes in the earth where volcanic gases are released)

Hot springs

Geysers

Explanation:

The most active geothermal resources are usually found along major tectonic plate boundaries where most volcanoes are located. One of the most active geothermal areas in the world is called the Ring of Fire, which encircles the Pacific Ocean.

When magma comes near the earth's surface, it heats ground water trapped in porous rock or water running along fractured rock surfaces and faults. Hydrothermal features have two common ingredients: water (hydro) and heat (thermal).

Geologists use various methods to find geothermal reservoirs. Drilling a well and testing the temperature deep underground is the most reliable method for locating a geothermal reservoir.

Mitochondria are the powerhouses of eukaryotic cells. Roughly, an average size mitochondrion can be modeled as a cylinder of rad
Leni [432]

Answer:

10.275 ∪m

Explanation:

To find the surface area of mitochondria, therefore, is the sum of the surface area of a cylinder and 2 half-spheres (the two caps) (-which is similar to one sphere).

The surface area of lateral sides of the cylinder = 2πr*h = 2 x 3.142 x 0.57 x 2.2 = 6.192

The surface area of sphere = 4πr²  = 4 x 3.142 x (0.57)² = 4.083

Total surface area = 6.192 + 4.083 = 10.275
