(PLEASE HELP!) If you can find a magnet or two in your house, gather them as well as a few small objects such as a paper clip, a coin , a small rock, or a toy car. If possible, use these materials to gather more evidence about the Investigation Question: How do magnets move objects? Write and/or draw (Insert Drawing ) your observations

How does an observation about an object differ from an inference about that object

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
