Archaeologists use a mass spectrometer to seperate the nitrogen isotopes 14N and 15N. The +1 ions of 15N enter the spectrometer with a speed of 8.5 km/s, and they travel in a circular arc of radius 25.0 cm. The magnetic field in the spectrometer has strength 5.29*10^-3 T. What is the mass of a 15N atom? Let the charge on a proton q=1.6*10^-19 C.
2.49*10^-26 kg
4.01*10^-25 kg
3.40*10^-22 kg
2.49*10^-23 kg

Six pendulums of mass mand length las shown are released from rest at the same angle theta from vertical. rank the pendulums according to the numberof complete cycles of motion each pendulum goes through perminute. a. l= 1m m=2kg b. l= 4m m=1 kg c. l= 2 m m= 2 kg d. l= 1 m m= 4 kg e. l= 2 m m = 4 kg f. l= 4m m = 4kg

Employer informs its employees that it will hold a substantial cash prize drawing for each work group at the end of each month in which no employee in the work group sustains a lost-time injury. tyra reports an injury that she sustained while operating a mechanical power press. tyra did not violate any employer safety rules when she sustained her injury. tyra’s injury requires her to miss work for two days. her employer cancels the cash prize drawing for that month for tyra’s work group because of tyra’s lost-time injury. did the employer misuse an incentive program to retaliate against tyra?
