Which part of the electromagnetic spectrum generally gives us our best views of stars forming in dusty clouds?

<span>We can see stars forming in dusty clouds because of the infrared portion of the electromagnetic spectrum. Infrared waves pass through dust in outer space more easily than visible light. Interstellar dust absorbs visible light, a phenomena known as dust extinction.</span>

Scientists have concluded that the uppermost part of the mantle is partially-molten. Which observation helped them reach this co
Olenka [21]

Answer:

 P and S waves slow down when they reach this layer. The asthenosphere, also known as the magma chamber, is the uppermost component of the mantle. This layer is partially molten and is a ductile zone in a tectonically poor state.

It's almost hard and seismic waves move through the asthenosphere at a slow rate. The fragile lithosphere and the uppermost portion of the asthenosphere are assumed to be rigid.

seismic waves travel more quickly through denser materials and therefore generally travel more quickly with the depth it moves more slowly through a liquid than a solid. Molten areas within the Earth slow down P waves and stop S waves because their shearing motion cannot be transmitted through a liquid. Partially molten areas may slow down the P waves and attenuate or weaken S waves.

hope this helps...

What is the resistance force when you walk up an inclined plane?<br> Please help quick!
Dominik [7]
Friction
Friction also affects the movement of an object on a slope. Friction is a force that offers resistance to movement when one object is in contact with another. Imagine now that you were on the downside of the object and applying force to keep the object in the same place (not moving)

Germanium to which 1024 m-3 Ga atoms have been added is an extrinsic semiconductor at room temperature, and virtually all the Ga
Svetlanka [38]

Answer:

Electrical Conductivity is 3200 (\Omega m)^{-1}

Solution:

As per the question:

N_{A} = 10^{24}\ m^{- 3}\ Ga\ atoms

Mobility of electrons, \mu_{e} = 0.26\ m^{2}/ Vs

Mobility of holes, \mu_{h} = 0.020\ m^{2}/ Vs

Charge, Q = 1.6\times 10^{- 19}\ C

Now,

The formula for the conductivity is given by:

\sigma = N_{A}Q\mu_{h}

\sigma = 10^{24}\times 1.6\times 10^{- 19}\times 0.020} = 3200(\Omega m)^{-1}
