What is the phase angle in a series RLC circuit at resonance.

The fission of U-235 begins with the absorption of a slow-moving neutron that produces an unstable nucleus U-236. Calculate the energy released in MeV carried off by the fission fragments. Reaction:           Masses:

Suppose the ray, in air with n = 1.00, enters a slab with n = 2.50 at a 45.0° angle with respect to the normal, then exits the bottom of the slab into water, with n = 1.33. At what angle to the normal does the ray leave the slab?

A series RCL circuit contains a 148-ohm resistor, a 1.50 x 10^-6 F capacitor, and a 35.7-mH inductor. The generator has a frequency of 512 Hz and an rms voltage of 35.0 V. Determine the rms current in the circuit.    

What is the wavelength (in vacuum) of the 0.186-MeV gamma-ray photon emitted by radium ? [ Note: 1 eV = 1.60 x 10^-19 J and Planck’s constant, h = 6.63 x 10^-34 J.s and the speed of light in a vacuum is 3.0 x 10^8 m/s]

The atomic mass of oxygen is 15.999 u. Convert this mass to grams.

A nurse is preparing  to administer Vancomycin 1 g by intermittent IV bolus. Available is Vancomycin 1g in 100mL of dextrose 5% water(D5W) to infuse over 45 minutes. The drop factor of the tubing is 10gtt/mL. The nurse will deliver how many gtt/min ? Round to the nearest whole number.Do NOt use trailing zeros.

Electrons carry a negative electric charge and revolve about the nucleus of the atom, which carries a positive electric charge from the proton. Th e electron is held in orbit by the force of electrical attraction at a typical distance of 1.00 × 10^–10 m. What is the magnitude of the force exist between an electron and proton?

A child who weighs 20 kg is prescribed an intravenous (IV) aminophylline (Truphylline) loading dose of 500 mg. What is the nurse’s best action?

The nurse is monitoring a patient with a confirmed ventricular arrhythmia. Which medications does the nurse anticipate being ordered? (Select all that apply.)
