Answer:
Fluid friction.
Explanation:
Friction can be defined as a force that resists the relative motion of two objects when there surface comes in contact. Thus, it prevents two surface from easily sliding over or slipping across one another. Also, friction usually reduces the efficiency and mechanical advantage of machines but can be reduced through lubrication.
Generally, there are four (4) main types of friction and these includes;
I. Static friction.
II. Rolling friction.
III. Sliding friction.
IV. Fluid friction.
Fluid friction can be defined as a type of friction that acts on objects moving through a liquid or gas. A fluid refers to any physical substance that can flow and is able to take the shape of a container.

<span>The "product line" rule must be used to find out the number of ways that two representatives can be picked so that one is a mathematics major and the other is a computer science major.

The product line states that if the two functions f(x) and g(x) are differentiable (i.e. the derivative exist) then the product is differentiable and:
(fg)'=f'g+fg'
Because the pacemaker is a very high-risk device, but has the opportunity to pose fewer risks, it should be classified as a significant risk device.
