Tidal forces are greatest when the Eaetg, the sun and the moon are in line. When this occurs at the Annapolis Tidal Generating Station, the waterhas a maximum depth of 9.6 m at 4:30 pm and a minimum depthof 0.4 m 6.2 hourslater. the equation is: y= 4.6cos (2pi/12.4) (t-4.5) + ...

How bright a star appears can depend on how much light the star actually emits and how far away it is. The stellar magnitude scale can be adjusted to account for distance as follows: M2-M1 = log (b1 / b2) Here, M refers to a star's absolute magnitude, that is, how brightly...

The vertical position, h, in metres, of a gondola on a Ferris wheel is modelled using the function h = 10 sin ((pi/15) (t-d)) + 12 where t is the time, in seconds. The gondola must assume a vertical position of 7 m at t=0 s , and be on its way upward. Determine the phase shift...
