- Show that the Gregorian calendar will be in error by 1 day in about 3300 years.arrow_forwardConsider a calendar based entirely on the day and the month (the Moon’s period from full phase to full phase). How many days are there in a month? Can you figure out a scheme analogous to leap year to make this calendar work?arrow_forwardPlease refer to the picture for the formulas and constants that have to be used and shown in this problem. It takes light about 1.25 second to reach the moon from Earth. The moon orbits Earth about once every 27.3 days. Part 1) Estimate the mass of Earth Part 2) The force of Earth's gravitational pull on the moon is about 2.0 x 10^20 N. Estimate the mass of the moon. Part 3) The moon has a radius of 1.7 x 10^6 m. On the surface of the moon, what is the acceleration due to moon's gravity? Part 4) How many g's is your answer to part c? Or what percentage of Earth's gravity would you experience on the moon? Part 5) If you stood on the moon and jumped straight up with a velocity of 1.0 m/s, how long would it be before you landed back on the moon's surface? Please answer all parts.arrow_forward

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
- In aviation, it is helpful for pilots to know the cloud ceiling, which is the distance between the ground and lowest cloud. The simplest way to measure this is by using a spotlight to shine a beam of light up at the clouds and measuring the angle between the ground and where the beam hits the clouds. If the spotlight on the ground is 0.75 kmkm from the hangar door as shown in the image below, what is the cloud ceiling?arrow_forwardTwo of the interior angles of a triangle are 44.7 degrees and 62.1 degrees. What is the third interior angle of the triangle?arrow_forwardA baseball hit just above the ground leaves the bat at 24 m/s at 45 degrees above the horizontal. How far away does the ball strike the ground? Can you visually show the above. It has to do with right angles and trigonometric functions, but I need your explanation to understand how this works, as I am new to this.arrow_forward
