- An object circles the Sun at a distance equal to one half the Earth's distance from the Sun. How many years will it take the object to circle the Sun one time?You have walked around the rim of a large circle whose radius is 2.1 miles. The GPS tells you that you have walked a path length of 8 miles. What angular distance (in radians) have you walked?Consider the Earth's orbit around the Sun to be circular with radius R = 9.30 x 107 mi and it takes 365 days to complete one revolution. What is the distance Earth traveled for one revolution (circumference of a circle is 2??2πR )?
- A ferris wheel completes 2 revolutions in 60 seconds. Determine how far it has travelled in 15 seconds. the radius of the ferris wheel is 10 m.Venus and Earth both orbit the Sun. Assuming the orbits of these two planets are circles, find the ratio between their speeds in terms of their semi-major axes. Given that Earth's speed is 29.8 km s−1, find the speed of Venus as it orbits the Sun.According to Kepler's third law of planetary motion, the mean distance D, in millions of miles, from a planet in our solar system to the sun is related to the time P, in years, that it takes for the planet to complete a revolution around the sun, and the relationship is D = 93P 2/3. It takes the planet Pluto 248 years to complete a revolution around the sun. What is the mean distance from Pluto to the sun? What is the mean distance from Earth to the sun? Give your answers to the nearest million miles. from pluto to sun _____ million miles from earth to sun _____ million miles
- A ball traveling in a circle with a constant speed of 3.9 m/s has a centripetal acceleration of 5.8 m/s squared. What is the radius of the circle?Uniform circular motion involves three key variables: the moving object's speed, the size of the circle, and the time it takes to go around once. A circle's circumference equals its radius multiplied by 2?. The time it takes to complete one full circular "orbit" is called the period. Examples: The period of Earth's orbit around the Sun is about 365 days, and the period of the Moon's orbit around the Earth is roughly 28 days. A circle has the following labels. The label circumference is on the outside of the circle. A dot at the center of the circle is labeled center. A line extending from the center to the edge of the circle is labeled radius. A line extending from one side of the circle, through the radius, and to the other side of the circle is labeled diameter. The following equations are next to the circle: diameter = 2 ✕ radius d = 2r circumference = ? ✕ diameter circumference = 2? ✕ radius c = ?d c = 2?r Let's put these ideas to work. Suppose it takes a horse 20.0 seconds to…A small moon with a mass of 100 kg orbits a very dense asteroid with a mass of 1 million kg. The time for one complete orbit is 100 days.
