WHICH OF THE FOLLOWING STATEMENTS CANNOT BE DETERMINED FROM THE DIAGRAM

Option (B).

Step-by-step explanation:

Option (A).

A, F and B are lying on a line on the plane M.

True.

Option (B).

CD lies on the plane M, but its not clear that angle between the plane M and P is 90°.

False.

Option (C).

A, B and C are coplanar.

Since, these three points lie on the plane M, they are coplanar.

True.

Option (D).

Plane M intersects plane P in FH.

Since, line of intersection of the two planes M and P will be FH.

True.

Therefore, Option (B) will be the correct option.

answer: need picture of problem

step-by-step explanation:

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
