The gravitational force of attraction between two students sitting at their desks in physics class is 3.9 × 10−8 n. if one student has a mass of 56.5 kg and the other has a mass of 61.5 kg, how far apart are the students sitting? the universal gravitational constant is 6.673 × 10−11 n · m2 /kg2 . answer in units of m.

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

The seven sisters, seven stars located more than 400 light-years away in the taurus constellation can be seen here with venus and another constellation, orion. the seven stars stay grouped together but seem to move, like the planet venus. why do stars seem to move like planets in the night sky?
