Two isotopes of carbon, carbon-12 and carbon-13, have masses of 19.93 × 10-27 kg and 21.59 × 10-27 kg, respectively. These two isotopes are singly ionized (+e) and each is given a speed of 8.387 × 105 m/s. The ions then enter the bending region of a mass spectrometer where the magnetic field is 0.7817 T. Determine the spatial separation between the two isotopes after they have traveled through a half-circle. Use 1.602 × 10-19 C as the elementary charge and give your answer to four significant figures.
A runner covers one lap of a circular track 40.0m in diameter in 63.5s a) average speed for that lap? b) average velocity for that lap? c) If she covered the first half-lap in 28.6s , what was her average speed for that half-lap?
A grocery sack can withstand a maximum of 310 N before it rips. Will a bag holding 20.0 kg or groceries that is lifted from the checkout counter at an acceleration of 5.5 hold?
King Arthur's knights fire cannon from the top of the castle wall. The cannonball is fired at a speed of 60 m/s and an angle of 33. A cannonball that was accidentally dropped from the top of the castle wall hit the moat below in 1.80s.
