Identify the type of friction acting in each scenario. a surfer rides an ocean wave. a bowling ball travels down a bowling lane. a baseball flies through the air. a hose rests on the edge of a truck.

Explanation;

1. Fluid friction: Friction between the layers of fluid moving relative to each other.It is the force which resist the motion of fluid in itself or any other medium moving through fluid.

2. Rolling friction is the force which the resists the motion of any rolling object.

3. Static friction is the force which the keeps the object at rest.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
