if the distance between earth and sun
were half the present distance ?
Consider a planet of radius 10 x 106 m for which the length of a sidereal day is 5 x 104 s. Calculate the speed you would have with respect to the center of the planet, in m/s, if you were at a latitude of 5 degrees north.
(Please answer to the fourth decimal place - i.e 14.3225)

- 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?arrow_forward2) Calculate the difference in the geostationary altitude ( in km ) by by using solar day (24 hrs) and sidereal day (23hrs 56mins and 41 secs) 129.768 64.884 32.442 1000arrow_forwardConsider a calendar based entirely on the day and the month (the Moon’s period from full phase to full phase).

- What should be the duration of the year if the distance between the earth and the sun gets doubled?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"Aristarchus' Method of Determining the Distance to the Sun" At the first quarter of the Moon (at position Q), the angle (EQS) equals 90° (see the sketch below). Modern observations show that the interval from new Moon (near position N) to first quarter (at Q) is 35 minutes shorter than that from first quarter to full Moon (near position F). Given that the lunar synodic period (the interval between two identical lunar phases) is 29 days and 12.73 hours, estimate the Earth-Sun distance (ES) in terms of the Earth-Moon distance.arrow_forward
