Question 1
For each cart, calculate the time it took the cart to break the beam of the first photogate (A) (gate state 1) and travel to the second photogate (B) (gate state 1). Enter it into the table.

The gravitational force between pluto and charon is 3.61 × 1018 n. pluto has a mass of 1.3 × 1022 kg, which is only slightly greater than charon’s mass of 1.6 × 1021 kg. how far apart are pluto and charon? 2.0 × 107 m 2.4 × 1012 m 3.8 × 1014 m 5.8 × 1024 m
