Answer:
The correct answer is - option C. Law of superposition.
Explanation:
According to the law of superposition states that within a sequence of layers of natural sedimentary rock without any disturbance, the oldest layer is lies under the younger layers with ascending order in the sequence.
If a sedimentary rock has 4 layers as a, b, c and d where the younger layer d would be on top and the oldest layer a would be at the bottoms.
Thus, the correct answer is - option C.
Answer is: heat energy.
Braking is the process of controlling the velocity of an object (in this example bicycle) by inhibiting its motion.
Mechanical energy can be either kinetic or potential energy and has to do with the energy of position and motion of an object.
Kinetic energy is energy of the speed of an object and how much mass it has; basically how the object is moving.
Potential energy is type of energy is stored energy; it can be increased by getting into a higher position and/or stretching an object such as a rubber band.
A mechanical brake applies a friction force to convert the kinetic energy of the bicycle into heat energy which then dissipates into the atmosphere.
D. to preserve the union. He changed the meaning of the war when he passed the Emancipation Proclamation in 1863.
