The two sides of the DNA double helix are connected by pairs of bases (adenine, thymine, cytosine, and guanine). Because of the geometric shape of these molecules, adenine bonds with thymine and cytosine bonds with guanine. The figure (Figure 1) shows the thymine- adenine bond. Each charge shown is te, and the H-N distance is 0.110 nm
Consider two identical waves travelling in the positive x-direction. The two waves start at the same position but at different times, t1 and t2. What should the time difference At be in order to have a phase difference of T/4. Assume that the frequency of each wave is f = 20 Hz.

Figure is a cross-sectional view of a coaxial cable. The center conductor is surrounded by a rubber layer, which is surrounded by an outer conductor, which is surrounded by another rubber layer. In a particular application, the current in the inner conductor I 2 is 6.00 A out of the page and the current in the outer conductor I 1 is 2.00 A into the page. Assume that l = 1.80 mm. Determine the magnitude and direction (upward or downward of the page) of the magnetic field at point b. (Choose upward of the page as the positive y-direction and express the magnetic field by using the sign of the result, which must be in µT and without decimals. That means if you get a result of a 922 and the direction of the field is upward of the page, just type 922 or if you find the direction of the field as downward of the page, just tpe -922 in the answer box. Maximum of 2% error is accepted in your answer. Take vacuum permeability µ 0 = 4π x 10 -7 T /A 2 and π = 3.14.)
