Yes a igneous rock can be changed into another igneous rock. the reason behind it is when rocks melt they become magma or lava. when lava flows on the surface of the earth it crystallizes quickly and makes small crystals. but when they cool slower they make larger crystals. yes igneous rocks can change but only through extreme temperatures.
Answer:
.b.Be faster, less power consuming than silicon and much thinner
Explanation:
Graphene has a <em>very high electrical conductivity</em> due to its pi orbitals overlap that enhance the carbon to carbon bonds. This means that a nanoelectronic devise that uses graphene will be faster and will consume less powe and it will be thinner because graphenes have a <em>size of 0.345Nm.</em>

Answer:
1.After 11 hours, the cruise ship will be _233.75__nautical miles from the lighthouse.
2.At the start of the journey, the cruise ship was _10.5__
nautical miles from the lighthouse.
3.The cruise ship is traveling at a speed of_21.25_ nautical miles per hour.
Explanation:
Distance covered in 2 hours= 95.5-53NM
=42.5NM
therefore,
put value of distance and time in equation (1)
therefore,
speed=21.25NM/hour
Therefore distance covered in 11 hours= speed* time
=233.75NM
2. Since distance covered in 2 hours is 42.5
therefore, at starting of the journey the cruise distance from light house is
= 53NM-42.5NM
=10.5NM
3. Distance covered in 2 hours= 95.5-53NM
=42.5NM
therefore,
put value of distance and time in equation (1)
therefore,
speed=21.25NM/hour
Therefore Cruise ship is traveling at speed of 21.25NM/hour
