Final answer:
True, we can use the Pythagorean theorem to calculate the length of the resultant vector obtained from the addition of two vectors that are at right angles to each other.
Step-by-step explanation:
The answer is True. We can use the Pythagorean theorem to calculate the length of the resultant vector obtained from the addition of two vectors that are at right angles to each other.
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. In this case, the two vectors that are at right angles to each other form the legs of the right triangle, and the resultant vector is the hypotenuse.
By applying the Pythagorean theorem, we can find the magnitude of the resultant vector by taking the square root of the sum of the squares of the lengths of the two vectors. This allows us to calculate the length of the resultant vector.
