A proton moving at $v = 10^6$ m/s enters a constant electric field with a strength of $E = 1$ V/m, perpendicular to its path. To prevent the proton from altering its trajectory or speed, a counteracting magnetic field must be introduced. What is the minimum magnitude required for this magnetic field? ? a. $10^{-6}$ T ? b. 1 T ? c. $10^3$ T ? d. $10^6$ T ? e. None of the above

Example: A ball is thrown straight up with a velocity given by v(t) = 32t + 20 ft/s, where t is measured in seconds. Find and interpret âˆ«v(t) dt. Explanation: Using the Second Fundamental Theorem of Calculus, we have âˆ«(32t + 20) dt = 16t^2 + 20t + C. Thus, if a ball is thrown straight up into the air with velocity v(t), the height of the ball, 1 second later, will be 4 feet above the initial height. Note that the ball has traveled much farther. It has gone up to its peak and is falling down, but the difference between its height at t=0 and t=1 is 4 ft.

The amplitude axis should be on a dB scale and the time axis in microseconds. Ignore any reflected signal from the transducer/fat interface and assume that a signal of 0 dB enters the body. At a transducer frequency of 5 MHz, the linear attenuation coefficient for muscle and liver is 5 dB cm$^{-1}$, and for fat is 7 dB cm$^{-1}$. Relevant values of the characteristic acoustic impedance and speed of sound can be found in Table 10.1. 5 mm fat Figure (a) liver
