could you please answer

Example An experimental device imparts a force of magni- tude F = 225 N to the front edge of the rim at A to simulate the effect of a slam dunk. Determine the 900 mm 700 mm F moments of the force F about point O and about point B. Finally, locate, from the base at 0, a point C on the ground where the force imparts zero moment. B 300 mm 3050 mm

Problem 1. “Hot Jupiter” Exoplanets  A number of gas giant planets orbiting other stars at distances less than 1 A.U. have been discovered. Because of their proximity to their parent stars, and their compositional similarity to Jupiter, they have been labeled “Hot Jupiters”.   The orbital radius of one of these planets is 0.06 A.U. with average orbital speed 600 km/sec. What is the length of this planet’s year in Earth (solar) days? Estimate the mass, M, of its parent star in terms of the mass of the sun (M) using Newton’s first form of Kepler’s 3rd Law.

4.6 Halley Hesitation Halley's comet was last visible from the Earth in the very early mornings of 1986. I was 15.0 years old at the time and never got around to seeing it. I have to wait until I am 90.6 to get another chance! The comet has a highly elliptical orbit and comes within 0.57 AU of the sun on its closest approach. What is the furthest the comet gets from the sun in AU? AU is the symbol for astronomical unit, and is the average distance between the sun and earth:1.49 x 10¹¹ m

question 2a please

1.between which two points do you measure the distance between spherical objects when you calculate a gravitational force? 2.explain the meaning of the word "universal" 3.explain why you are unable to feel the gravitational force of attraction between you and, for an example,a book on a table. 4.consider the variables in newtsons law of universal gravitation and suggest why the gravitational force of the earth and the sun on each other is strong enough to keep the earth in it's orbit around the sun. 5.the distance between the centres of two mass pieces of 6kg and 4kg is 3 m. 6.calculate the mangnitude of the gravitational force that they exert on each other

Can you please answer this question and show the steps

Part A Kepler's Third "Law" states that the square of the orbital period of a planet (T) is proportional to the cube of the planet's average orbital radius (r), T² = kr³, where k is the proportionality constant connecting T2 and We can derive Kepler's Third "Law" and show that k = 4/Gmgun, where G is the universal gravitational constant and msun is the mass of the sun, by %3D preventing a global thermonuclear war before it ruins our day and then binge watching the first ten seasons of the Walking Dead on Netflix. setting the acceleration due to gravity at the surface of the planet equal to the acceleration due to gravity at the surface of the sun. O setting the mutual gravitational force between the planet and the sun, Gmplanetmsunr, equal to the centripetal force acting on the planet. O stealing Robert Hooke's undeveloped idea that the mutual attractive force between the planet and the sun is proportional to 1/2. convincing ourselves that planets in circular orbits are actually in…

Tutorial The Magellan orbiter orbits Venus with a period of 3.26 hours. How far (in km) above the surface of the planet is it? (The mass of Venus is 4.87 × 1024 kg, and the radius of Venus is 6.05 × 103 km.) Part 1 of 3 The period of the orbiter's orbit can give us the speed at which the orbiter orbits the planet. We imagine the orbiter tracing a circle around the planet at a certain height, the speed is 27tr V = Part 2 of 3 Next, we combine this with the circular velocity equation to determine the height above the planet's surface. GM V = 27tr GM Squaring both sides and solving for r gives the following equation. What is the exponent for r? U. GM 472
