Final answer:
The suffix -RRHAPHY indeed denotes surgical suturing which is true. In Physics, using the Pythagorean theorem to find the resultant vector of two perpendicular vectors is true, while only angles are not sufficient to find the resultant vector's angle, which is false. Vectors can indeed be represented as a right-angle triangle through their x and y components, and cotton was an economic basis for the South during Reconstruction, which is true.
Step-by-step explanation:
True or False Questions in Physics
True or False- The suffix -RRHAPHY means surgical suturing? This question is true as the suffix -RRHAPHY relates to the medical term for surgical suturing.
Now, let's address the physics-related questions provided:
36. True or False-We can use Pythagorean theorem to calculate the length of the resultant vector obtained from the addition of two vectors which are at right angles to each other. The answer is true. When two vectors are perpendicular, you can use the Pythagorean theorem to find the magnitude of the resultant vector, much like finding the hypotenuse of a right-angled triangle.
GRASP CHECK
True or False-If only the angles of two vectors are known, we can find the angle of their resultant addition vector. The answer is false. You cannot find the resultant angle with only the knowledge of the angles of the two original vectors; you also need to know their magnitudes.
60. True or False-A vector can form the shape of a right angle triangle with its x and y components. This statement is true. Any vector can be broken down into its x (horizontal) and y (vertical) components, forming a right-angled triangle where the vector itself is the hypotenuse.
? Exercise 17.3.4
Cotton formed a strong economic basis for the South during Reconstruction. This statement is true. After the Civil War, during the Reconstruction era, cotton remained a key economic asset for the southern United States.
