As the angle between a given vector and the +x axis increases from 0* * 1 point to 90", the magnitude of its vertical component (or y-component) O increases O decreases O increases then decreases O decreases then increases 16. Analyze each statement carefully. Which statement has a vector * 1 point quantity? The area of a standard Olympic swimming pool is 1250 square meters. O When a comet is far from the Sun, it travels at about 2000 miles per hour. Reaching an elevation of 8849 m, Mt Everest is the highest mountain in the world. O The Batanes Group of Islands is located at approximately 162 km, north of the Luzon main island. 17. Velocity is a vector quantity.
