3. Suppose mat a pur spends this extra time doing moderate physical work. II ICI TOU much weight will she lose in one year? 4. The speed of blood in an artery or vein can be measured using an electromagnetic blood flow meter. A blood vessel of radius R is oriented perpendicular to a magnetic field B. lons in the blood, which is moving with speed v, experience a Lorentz force. Positive ions move to one side of the vessel and negative ions move to the other side, establishing an electric field E whose force just balances the magnetic force. If B = 0.1T, & = 10-6V and R= Imm, what is speed of blood flow v and rate of flow Q (Q = vA)?

When a stat erupts in a supernova explosion, huge numbers of electron neutrinos are formed in nuclear reactions. Such neutrinos from the 1987A supernova in the relatively nearby Magellanic Cloud were observed within hours of the initial brightening, indicating they traveled to earth at approximately the speed of light. Explain how this date can be used to set an upper limit on the mass of the neutrino, noting that the mass is small the neutrinos could travel very close to the speed at light and have a reasonable energy (on the order of MeV).
