Webif the diameter is given we find the circumference by diameter x pi, so if the radius is half the value of the diameter then if you are only given the radius we find the circumference by radius x 2 x pi because radius x 2 = diameter 12 comments ( 93 votes) Upvote Show more... Blake Terryberry 2 years ago WebWe use Equation 13.7 and Equation 13.8 to find the orbital speed and period, respectively. Solution Using Equation 13.7, the orbital velocity is v orbit = G M E r = 6.67 × 10 −11 N · m 2 /kg 2 ( 5.96 × 10 24 kg) ( 6.36 × 10 6 + 4.00 × 10 5 m) = 7.67 × 10 3 m/s which is about 17,000 mph. Using Equation 13.8, the period is

WebSince the ISS orbits 4.00 × 10 2 km 4.00 × 10 2 km above Earth’s surface, the radius at which it orbits is R E + 4.00 × 10 2 km R E + 4.00 × 10 2 km. We use Equation 13.7 and Equation 13.8 to find the orbital speed and period, respectively. WebThe ratio of the circumference C C to diameter d d of both circles is \redD {3.14159...} 3.14159... \dfrac {C} {d} = \redD {3.14159...} dC = 3.14159... This turns out to be true for all circles, which makes the number \redD {3.14159...} 3.14159... one of the most important numbers in all of math! WebQuestion: A rock, initially at rest with respect to Earth and located an infinite distance away is released and accelerates toward Earth. An observation tower is built 3 Earth-radii high to observe the rock as it plummets to Earth. Neglecting friction, how much greater is the rock's speed when it hits the ground than its speed at the top of the tower? 1: twice 2: north bay village utilities
