Final answer:
The statement regarding the product-of-sums form being called the minterm form is false. Other true/false statements are addressed with explanations, covering concepts from vector addition to wave interference and electrical charges.
Step-by-step explanation:
The statement 'The product-of-sums form of Boolean expressions is called the minterm form by engineers, technicians, and scientists.' is false. In Boolean algebra, the product-of-sums is a form where several sums (OR operations) are multiplied together (AND operations). On the contrary, the minterm form is also known as the sum of products, where several products (AND operations) are summed together (OR operations).
Now addressing other statements:
- It is true that the Pythagorean theorem can be used to calculate the resultant vector's length when adding two vectors that are perpendicular to each other.
- The statement 'The two types of interference are constructive and destructive interferences.' is true.
- A vector can indeed form the shape of a right angle triangle with its x and y components, so this is true.
- The word 'hypothesis' is closest in meaning to 'suggestion'.
- The concept of a work function is not applicable in the classical wave model, so this is false.
- High-voltage wires are held aloft by insulating connectors, but are not typically wrapped in an insulating material due to their high elevation and distance from objects; this statement is false.
- The efficiency of a simple machine is always less than 100 percent due to friction, making this statement true.
- For waves, the amplitudes add up when the waves are coherent and phase-aligned, not necessarily propagating in the same line, so this statement is false.
- The electric-field lines from a positive point charge indeed spread out radially and point outward, thus this statement is true.
