Answer:
carpet
Explanation:
Diffuse reflection is the reflection of light from a surface such that an incident ray is reflected at many angles rather than at just one angle as in the case of specular reflection.
The structure of carpet's surface is as shown. Thus it shows large amount of diffuse reflection.
<span>PV = nRT
moles of H2 = 1/2 = 0.5
moles of He = 1/4 =0.25
T = 273 + 27
partial pressure of H2
Px1 = 0.5x0.083x300
P=12.45 atmospheres
PP of He
px1 = 0.25x0.083x300
P =6 22 atmospheres
Totla pressure = 6.22 + 12.45 = 18.68 atm</span>
Answer:
20 5/6 sec
Explanation:
To find the solution we divide 5000 by 240
However, when you see a problem, always try to simplify
5000/240=500/24=250/12=125/6
Now the division is much easier

a. subduction.
Explanation:
A subduction zone is a zone where the oceanic crust dives beneath the continental crust.
- Subduction zones are typical features of convergent margins where two plates pulls together.
- They are formed by continent-oceanic covergence and ocean - ocean covergence.
- In oceanic - continent convergence, the denser oceanic crust slides under the continental crust because it is denser than the mantle below.
- In oceanic - oceanic crust convergence, either of the plate slides under the other into the mantle.
- Trenches, volcanoes, earthquakes are typical geologic features associated with them.

Answer:
Force between two charges is given as 143.3 N
Explanation:
As we know that electrostatic force between two point charges is given as
here we know that
also we know that
so we have
so we have
