Ser.01 In one of NASA's space tether experiments, a 20.0 km-long conducting wire was deployed by the space shuttle as it orbited at $7.86 \times 10^3$ m/s around Earth and across Earth's magnetic field lines. The resulting motional emf was used as a power source. If the component of Earth's magnetic field perpendicular to the tether was $1.72 \times 10^{-5}$ T, determine the maximum potential difference (in V) between the two ends of the tether.

or less turns? (ii) What is the expected number of turns it takes to reach $3? (iii) What is the expected number of turns it takes to reach $0? Consider the following equation: √(x + 5) = 7. Solve for x. Simplify the expression: (2x^2 + 3x - 5) / (x^2 - 4x + 3). Evaluate the integral: ∫(3x^2 + 2x + 1) dx. Solve the equation: 2x + 5 = 3x - 2. Find the derivative of the function: f(x) = 3x^2 + 2x + 1. Simplify the expression: √(4x^2 + 9) + √(x^2 + 1). Calculate the value of log(base 2) 16. Find the value of sin(π/4). Solve the equation: 5x - 2 = 3x + 4.

Back when I started chopping up DNA we often found ourselves short of funds: consequently we couldn't afford film to take pictures of gels. Instead we would lay Saran Wrap over the gel and painstakingly trace the bands leading to some rather dramatic looking UV burns. Here's one such tracing. Considering my remarkable accuracy with a Sharpie, use the available info in the tracing to map the DNA. 20000 10000 7000 5000 4000 3000 2000 1900 1000 700 500 400 300 200 75 R P R+P P+A R+A
