14000N is the correct answer
14000N
Assuming the truck maintained a constant speed up the slope, the work done to raise the truck's elevation against gravity would be equal to the gain in its potential energy. The force required to perform this work would be the component of the truck's weight parallel to the slope, which can be calculated using trigonometry.
Answer is 14000N.
100 and 600 WHAT?
Contour lines on a on a topographic map indicate elevations. Since elevation changes gently on gentle slopes the contour lines are further apart. Elevation changes rapidly on a steep slope so the contour lines are closer together.
Contour lines that are far apart indicate a gentle slope. Because contour lines connect points with the same elevation, wide spacing indicates that the elevation is not changing drastically.
Friction on a water slide can be reduced by using smoother materials for the slide surface, adding water to the slide to create a slippery layer, or applying a lubricant to the slide surface. Additionally, designing the slide with a gentle slope can help minimize friction.
When contour lines are farther apart, it indicates a gentle slope or gradual change in elevation in the terrain. This means the change in elevation over a given distance is more gradual.
You can reduce friction when getting dressed by wearing loose-fitting clothes, using fabric softener or lotion on your skin, and choosing seamless garments to minimize rubbing against your skin. Taking your time and being gentle while putting on clothes can also help decrease friction.
A high slope refers to a steep incline, meaning the elevation increases quickly over a short horizontal distance. A low slope, on the other hand, indicates a gentle incline with a gradual increase in elevation over a longer horizontal distance.
