PLEASE A planet's diameter is 2320 km, and its mass is 4.1 x 1020 kg. The probe you landed on this planet weighed 1500 N on the earth. What did it weigh on the surface of this planet?

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

Select the correct answer. what does the process of natural selection involve?

If anyone who can me with this hw? i would really appreciate it
