Black Friday deals can be a mix of real bargains and fake discounts. Some retailers may inflate the original prices to make the discounts seem larger than they actually are. It's important for consumers to do their research and compare prices before making a purchase to ensure they are getting a genuine deal. Additionally, some products may be older models or lower quality items that are being sold at a discounted price, so it's important to consider the value and quality of the product before making a purchase. **

Equipotential lines are always perpendicular to field lines because the electric field is always perpendicular to the equipotential surface. This is because the electric field is the gradient of the electric potential, and the gradient is always perpendicular to the equipotential surface. Therefore, the equipotential lines, which represent points of equal electric potential, must be perpendicular to the electric field lines. This relationship ensures that work done in moving a charge along an equipotential line is zero, as the electric field does no work in a direction perpendicular to its field lines. **

Show lines and working lines in dogs differ primarily in their breeding purpose and physical characteristics. Show lines are bred for conformation to breed standards and are often selected for their appearance in dog shows. Working lines, on the other hand, are bred for their ability to perform specific tasks such as herding, hunting, or protection work. Working lines tend to have a higher drive, energy level, and intelligence compared to show lines, as they are bred for their working abilities rather than their appearance. Additionally, working lines may have a more athletic build and higher stamina to excel in their designated tasks. **

Contour lines are lines on a map that connect points of equal elevation. They help to represent the shape and elevation of the land by showing how steep or gradual the terrain is. Contour lines that are close together indicate a steep slope, while contour lines that are further apart indicate a more gradual slope. By following contour lines, hikers and outdoor enthusiasts can better understand the topography of an area and plan their routes accordingly. **
