#4. What is the magnitude of A+B+C, where A=1.00 +3.00-1.00k, B=3.00-1.00-3.00k, and C=-1.00 +1.00j? A. 3.50 B. 5.83 C. 7.00 D. 8.75 E. 4.66 #5. When can we be certain that the average velocity of an object is always equal to its instantaneous velocity? A. Always B. Never C. Only when the acceleration is changing at a constant rate D. Only when the velocity is constant E. Only when the acceleration is constant
