Consider the mass spectrometer shown schematically in the figure below. The magnitude of the electric field between the plates of the velocity selector is 2.40 103 V/m, and the magnetic field in both the velocity selector and the deflection chamber has a magnitude of 0.040 0 T. Calculate the radius of the path for a singly charged ion having a mass m = 2.04 10-26 kg.

Suppose an enzyme has Km = 0.1mM and kcat = 10^3 s-1, and you perform an experiment in which [E]tot = 10-7M. Suppose that adding 0.1 µM of an inhibitor results in a Kmeff= 0.5 mM, and has no effect on kcat. Determine the substrate concentation that would be necessary to achieve a reaction velocity v of 5*10^-5Ms-1

In a series oscillating RLC circuit, R =16.0 W, C =5.0 mF, L =20.0 mH, and e=e_msin (wt) with e_m =45.0 V and frequency of oscillation is 50 Hz. For time t= 0.4 s find (a) the rate P_Cat which the energy in the capacitor is changing, and (b) the rate P_Rat which energy is being dissipated in the resistor.

A projectile is ground-launched into the air at time t = 0. The initial speed is vo and the angle to
the horizontal is ?. Air resistance is modeled as a drag force acting on the projectile and results
in an acceleration aD = ?kv where k is a constant and v is the velocity of the projectile. If the
effects of gravitational acceleration are included,

a) Determine expressions for the x- and y- components of the displacement of the
projectile as functions of time

Your design must be practical that can be fabricated and used in circuits.
