Question 1 of 3
A newly discovered dwarf planet named Eldoria orbits the Sun at a distance of 9 astronomical units (AU). Using the relationship that a planet’s orbital period (in Earth years) is the square‑root of the cube of its distance from the Sun (P = √(a³)), approximately how many Earth years does Eldoria take to go once around the Sun?
Question 2 of 3
A 3‑kg toy is placed on a planet where the gravitational field strength is 5 N kg⁻¹. What is the toy’s weight on that planet?
Question 3 of 3
A 10 kg object weighs 98 N on Earth, where the gravitational field strength is about 9.8 N·kg⁻¹. If the same object is taken to the Moon, where the gravitational field strength is about 1.6 N·kg⁻¹, what is its weight on the Moon?
