That is true the hemisphere that is tilted towards the sun receives more direct sin light. So it must be right
Answer:
Volcanoes may form at a fault where a transform fault exists is not a true statement.
Explanation:
olcThe volcanoes can be found across the globe, in most of the regions. What can be noticed though is that there is a high concentration of volcanoes a certain places, while there is much less or lacking in others. The places where there is high concetration of volcanoes are along the divergent and convergent plate boundaries, with isolated volcanic chains in the interior of the plates caused by hot spots.
The places where volcanoes are lacking, except the vast majority of the interior of the plates, are the transform plate boundaries. The reason for this is that at these plate boundaries the plates don't create a gap between each other and make the crust thinner so that magma can move toward the surface, instead, they slide past each other, thus create pressure between each other, which would make it even harder for magma to come out on the surface than in an interior of a plate.
Answer: composition in weight percent = 41.25% Cu and 58.75% Zn
Composition in Atom percent = 40.54% Cu and 59.46% Zn
Explanation:
Starting with the composition in weight percent.
Let Mcu= mass of cu and Mzn= mass of zn
%W= weight percent
%Wcu = (Mcu/(Mcu + Mzn)) × 100%
By substituting the values
%Wcu = (33/(33+47)) × 100%
%Wcu = (33/80) × 100%
%Wcu = 41.25%
%Wzn = (Mzn/(Mcu + Mzn)) × 100%
= 47/80 × 100%
%Wzn = 58.75%
Then we can proceed to composition in atom percent
Atomic mass of Cu= Ac = 63.5g/mol
For zn = Az = 65.4g/mol
Atom percent cu = {(%Wcu×Ac)/[(%Wcu×Ac)+(%Wzn×Az)]} × 100%
Substituting the values
= {2619.375/6461.625}×100%
=40.54% Cu
Atom percent zn = {(%Wzn×Az)/[(%Wcu×Ac)+(%Wzn×Az)]} × 100%
={3842.25/6461.625}×100%
=59.46% Zn

Im not sure if you speak english but the importance of laws for citizens to obey is to keep control of citizens actions as well as to try and maintain a safe environment around us.
ang kahalagahan ng mga batas para sa mga mamamayan na sundin ay upang mapanatili ang kontrol ng mga pagkilos ng mga mamamayan pati na rin upang subukan at mapanatili ang isang ligtas na kapaligiran sa paligid natin.
