Q.1) If a material has a longitudinal relaxation time constant T1 = 200 ms, what will the MR signal, S, be 200 ms after an RF pulse has flipped (nutated) the bulk magnetization into the transverse plane? Q.2) A sample of liver tissue has a longitudinal relaxation time constant T1 of 500 ms and a transverse relaxation time constant T2 of 40 ms. What will the MR signal be? a) 40 ms after an RF pulse? b) 500 ms after...
The relaxation modulus of a specimen of tissue is ?(?) = ?0?−?. What is the time dependent stress in this material if it is subjected to the time-dependent strain ?(?) = ? for ? < ?0, ?(?) = ??0 for ? > ?0?
4- Consider Problem 3. Calculate the new minimum pedestrian green time, assuming the effective crosswalk width is 6 ft and the maximum number of crossing pedestrians in any phase is 20. This is the problem 3 Two additional 12-ft through lanes are added to Vine Street, one lane in each direction. If the peak-hour traffic volumes are unchanged but the Vine Street left-turn saturation flow rates increase by 120 veh/h because of the added through lanes, what would the revised...
Determining the present value of bonds payable and journalizing using the effective interest amortization method Relaxation, Inc. is authorized to issue 7%, 10-year bonds payable. On January 1, 2018, when the market interest rate is 12%, the company issues $300,000 of the bonds. The bonds pay interest semiannually. Requirements 1. How much cash did the company receive upon issuance of the bonds payable? (Round to the nearest dollar.) 2. Prepare an amortization table for the bond using the effective-interest method,...
A 90-gram wire that is 10 cm long is under tension. When a transverse wave of frequency 890 Hz travels down the wire, it's wavelength is 0.10 and its amplitude is 6.5mm. What is the tension in the wire? What is the mode of this standing wave?
When a massive aluminum sculpture is hung from a steel wire, the fundamental frequency for transverse standing waves on the wire is 213.0 Hz . The sculpture (but not the wire) is then completely submerged in water. What is the new fundamental frequency? (Hint: The density of the water is 1000 kg/m3, and the density of the aluminium is 2700 kg/m3.) Express your answer using two significant figures. f = __________ Hz

Estimate the TEM residual vertical velocity in the westerly shear zone of the equatorial QBO assuming that radiative cooling can be approximated by Newtonian cooling with a 20-day relaxation time, that the vertical shear is 20 m s-1 per 5 km, and that the meridional half-width is 12° latitude.
