Suppose we observe that a sample of an unknown radioactive substance emits particles. In a magnetic field oriented vertically upward, we see that these particles bend to the left if we look along their direction of motion. Are the particles positively or negatively charged, or is it impossible to tell

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
