A planet has been observed orbiting a nearby star. This star has a mass of 3.5 solar masses, and the planet is 4.2 AU from the star. What is the planet’s orbital period in Earth years? Round your answer to the nearest whole number. I know the answer is 16 Earth years... but I don't understand how to get there. When I convert the solar mass and AU into kg and meters, respectively, and solve for the planet's orbital period, I get 0.11. Do you need to convert AU and solar mass into different units to use Kepler's laws (specifically Kepler's third law)? Please help, thanks

Two friends are having a conversation. anna says a satellite in orbit is in freefall because the satellite keeps falling toward earth. tom says a satellite in orbit is not in freefall because the acceleration due to gravity is not 9.80 m/2 . who do you agree with and why?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
