Adam, who is 5'6" tall, notices his shadow on the sidewalk. If the angle of elevation from the tip of the shadow to the sun is 6
german
<h2>Answer:</h2>

This problem can be solved using trigonomtry, assuming that the figure formed by Adam's shadow and Adam himself is a Right Triangle (as shown in the figure attached).


According to this,  the distance from the tip of the shadow to the top of Adam's head is the hypotenuse H of the triangle, and we already know Adam's height and the angle of elevation. So, the trigonometric function that best works in this case is sine:


sen(angle)=\frac{Oppositeleg}{hypotenuse}  


Where the opposite leg is the side of the triangle that is opposite to the 60\º angle.

In this especific case:


sen(60\º)=\frac{5.6feet}{H}     (1)


In order to know the value of the hypotenuse we have to find  H from equation (1):

H=\frac{5.6feet}{sen(60\º)}



H=6.4663 feet



Rounding:

H=6.46 feet>>>>>This is the distance from the tip of the shadow to the top of Adam's head

zimovet [89]

Cartographers can represent the spherical Earth on flat paper by making a projection which is like casting shadows from the spherical world onto a flat piece of paper

<u>Explanation</u>:

Cartographers otherwise known as map makers who combine nature and science through an acquired skill called cartography, it could serve as an efficient form of communicative technique for acquiring information through the procession of data.

Cartographers use PROJECTION to represent the spherical earth on a flat paper, through this scientific method, one could say that this structure reshapes reality in the human eye. There are steps or ways in which one can achieve a representation of the spherical earth on flat paper but it can only be foreseen by the complementarity of PROJECTION.

1)) Name and describe two mechanisms by which mantle rock can melt without an increase in temperature.
MaRussiya [10]

Answer:

<u>Called as mantel melting</u>

Explanation:

  • The mantel rocks can break and melt without the increase in temperature due to the overexerted pressure of the rocks.  
  • This process is called decompression melting. Rocks can melt in the mantel due to dehydration thus producing molten magma and lava.
  • As the rocks don't melt homogeneously there is a complex mixture of mineral content during the subduction and presence of volatile substances like the water or CO2.
