Which of the following statements about an inline cylinder configuration is false?
works well in eight cylinder engines
An inline cylinder configuration places the cylinders in a single row either completely vertical or slanted. Due to this arrangement, an inline cylinder configuration makes the engine longer and, although it works well in four cylinder engines, performace suffers in larger engines due to the difficulty in evenly distributing the air-fuel mixture over the length of the engine.
Someone who has Rh-factor __________ blood cannot receive blood with a __________ type.
negative, positive
Blood transfer is limited by the type and Rh factor of the blood. Someone who has Rh-factor negative blood cannot receive blood with a positive type but a person with Rh-factor positive type blood can receive Rh-negative blood. Type O negative blood is the universal donor because it can be given to a person with any blood type. Type AB positive is the universal recipient meaning someone with this blood type can receive any other type of blood.

Coplanar forces:
act in a common plane
Collinear forces act along the same line of action, concurrent forces pass through a common point and coplanar forces act in a common plane.
A right angle measures:
90°
A right angle measures 90 degrees and is the intersection of two perpendicular lines. In diagrams, a right angle is indicated by a small box completing a square with the perpendicular lines.
