<span>The softer a rock's composition is the slower it will weather, the harder a rock's composition the faster it will weather. Weathering weakens and breaks apart rocks. This is an example of how weathering affects the Earth's surface. No-Till Farming and Contour Farming are two examples of preventing soil erosion.</span>
Answer:
Explanation:
What a lot of words to solve such a simple problem! The perpendicular force is the one that is pushing straight down on the plane. There is no side to side movement here or friction acting on this dimension at all. Perpendicular force is the same as the weight of the block. That's it! Perpendicular force is also normal force which is the same thing as weight:
w = mg so
w = (4.04)(9.8) and
w = 4.0 × 10¹ N
The answer is 60%. If you divide the 9 and 5, you will get 0.6. So you just move the decimal point to the right twice. (:

Answer:
So, instead of fossil fuels, the magnetic field thats creatd by electrified coils in the guideway walls, and on the track combine to propel the train. Just think of it as playing with magnets. The opposite attract while if you put norh to north or south to south, they will push away from each ther. This is just the basic principle of electromagnetic propulsion
