MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A synchronous satellite, which always remains above the same point on a planet's equator, is put in circular orbit around Uranus so that scientists can study a surface feature. Uranus rotates once every 17.2 h. Use the data of this table to find the altitude of the satellite. km Need Help? Read It Watch It12. [-/1 Points] DETAILS SERCP11 7.A.P.052. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The dung beetle is known as one of the strongest animals for its size, often forming balls of dung up to 10 times their own mass and rolling them to locations where they can be buried and stored as food. A typical dung ball formed by the species K. nigroseneus has a radius of 1.85 cm and is rolled by the beetle at 6.15 cm/s. HINT (a) What is the rolling ball's angular speed (in rad/s)? rad/s (b) How many full revolutions are required if the beetle rolls the ball a distance of 1.75 m? rev Need Help? Read It Watch It
