The number of hours of daylight in Boston is given by y=3sin [2π(x - 79)/365] + 12, where x is the number of days after January 1. Solve, Within a year, when does Boston have 13.5 hours of daylight? Give your answer in days after January 1 and round to the nearest day.
The earth revolves around the sun in exactly 365 1/4 days which is equivalent to 1 year. To make up for the loss of 1/4 day, the calendar was adjusted so that we have a leap year for every 4 years. If the earth were to speed in its motion slightly so that a year would be completed in exactly 365 days and 6 hours, how often would we need to have a leap year?
2) Calculate the difference in the geostationary altitude ( in km ) by by using solar day (24 hrs) and sidereal day (23hrs 56mins and 41 secs)

- 1) How many kilometers are spanned by an arc of 0.5° latitude (Dj = 1°) along the DateLine? 2) At what latitude is the zonal distance spanned by an arc of 1° longitude (Dl = 1°) exactly half as long as the equivalent meridional distance spanned by an arc of 1° latitude (Dj =1°)?arrow_forwardIn a part of Earth’s orbit where Earth is moving faster than usual around the Sun, would the length of the solar day change? If so, how? Explain.arrow_forwardRight Ascension and Declination is a coordinate system for objects in the sky, and is analogous to longitude and latitude coordinates, respectively, for objects on Earth. Right ascension (RA) coordinates are given in hours (h), minutes (m), and seconds (s). Declination (DEC) coordinates are given in degrees (°), arcminutes ('), and arcseconds ("). Sirius is the brightest star in the night sky. Its RA and DEC coordinates are 6h 45 m 7.96 s and -16° 44' 78.6". Using unit conversion, find the RA coordinate only in hours and round the coordinate to 5 significant figures.arrow_forward
