you will have to remove the rear seat as the pump is located behind the backrest. To remove the back seat, you need an extension for your socket wrench and remove the two nuts which are about centered where each person sits. Then lift up the seat to clear four guide/retaining clips.Having done that,…

Answer The object is moving the speed of the water, not the speed of the wave. Example: when you are riding in a car, you are moving the the speed of the car not the speed of the bump in the road. The bumps in the water are mostly caused by wind & are like bumps in the road, but these…

As a falling object accelerates through air, its speed increases and air resistance increases. While gravity pulls the object down, we find that air resistance is trying to limit the object's speed. Air resistance reduces the acceleration of a falling object. It would accelerate faster if it was fal…

Water is made of tiny pieces called molecules. Heat makes molecules excited. They jump around and move quickly! They need space to do this. Cold, on the other hand, makes molecules slow down and it can make them nearly stop. They don't need as much room to move around and the space between them shri…

Capillarity is a result of surface tension. Surface tension causes liquid surfaces to be concave or convex. Due to this, there is greater pressure on the concave side of the liquid meniscus. To make the pressures at the same height equal, the liquid in the capillary rises or falls.

You can't really "bend" water. As a solid (ice), the hydrogen bonds make it pretty rigid and brittle. It tends to break before bending. The liquid has an extremely low resistance to shear forces.
