Answer:
4.0 m/s
Explanation:
acceleration = (16-2) /3.5 = 4 m/s
Answer: Yes it possible for a system to have negative potential energy, since the choice of the zero of potential energy is arbitrary.
Explanation:
Potential energy is defined as the energy present in an object due to its position.
Mathematically, P.E = mgh
A potential energy can be negative also. This is because zero potential energy is arbitrary. For example, at the top of a building the choice of potential energy can be zero.
Therefore, the potential energy below the building will be negative.
Answer:Dark minerals rich in iron and magnesium separate from light minerals rich in silica and aluminum.
Explanation: Metamorphic rocks are rocks formed as a result of the transformation of other existing rocks which can be Igneous or Sedimentary rocks,this transformation process is called METAMORPHISM. During metamorphism,rocks under Serious levels of stress which can lead to the separation of materials.
During this separation process,Dark minerals rich in iron and magnesium are separated from light minerals rich in silica and aluminum.
