Answer:

The answer is C.)There are areas in California that use the heat from deep in the Earth to generate electricity.

Explanation:

Geothermal energy is a renewable energy that is obtained by harnessing the heat inside the earth, that is, its objective is to take advantage of the heat energy that is inside the earth, which is transmitted through hot rock bodies or reservoirs by conduction and convection, where processes of interaction of underground water and rocks arise, giving rise to geothermal systems.

7. How much thermal energy is absorbed when 10.0 g of ice at 0.0 degrees C changes phase to liquid water at 0.0 degrees C? The m

Nesterboy [21]

Answer:

3.34 kJ

Explanation:

FIrst of all, we need to calculate the number of moles corresponding to 10.0g of ice. This is given by

$n=\frac{m }{M_m}$

where

$M_m = 18.02 g/mol$ is the molar mas

m = 10.0 g is the mass

Substituting

$n=\frac{m}{M_m}=\frac{10 g}{18.02 g/mol}=0.555 mol$

Now we know that the heat of fusion is

$H_{fus}=6.01 kJ/mol$

so the thermal energy needed to fuse the ice is

$Q=n H_{fus} = (0.555 mol)(6.01 kJ/mol)=3.34 kJ$

A brass rod with a mass of 0.300 kg slides on parallel horizontal iron rails, 0.440 m apart, and carries a current of 15.0 A. Th

Digiron [165]

Answer:

The magnitude of the magnetic field is $B = 0.0890 \ T$

Explanation:

From the question we are told that

The mass of the rod is $m =0.300 \ kg$

The distance of separation is $d = 0.440 \ m$

The current is $I = 15.0 \ A$

The coefficient of friction is $\mu = 0.300$

Generally for the rod the rod to continue moving at a constant speed

The frictional force must equal to the magnetic field force so

$F_m = F_f$

Where $F_m = B* I * d$

and $F_f = \mu * m * g$

$B*I *d = \mu * m * g$

=> $B = \frac{\mu * m * g }{I * d }$

substituting values

$B = \frac{0.2 * 0.300 * 9.8 }{ 15 * 0.440 }$

$B = 0.0890 \ T$

According to Newton’s first law of motion, what will an object in motion do when no external force acts on it?

Anarel [89]

Answer:

if no external force is acting on it so it will remain in motion acoording to inertia ( inertia is a property of matter it continues in existing state either in rest or motion
