All of the observations except "powerful gravitational field" are consistent with the current theory of black holes.
The gavitational field of a black hole is thought to be no different than that of an ordinary star with the same mass.
False. Both masses will experience an acceleration which depends on their mass. The small mass will experience a greater acceleration.
Atoms move at different speeds because of different amounts of space between each other (lots of space in a liquid so they move faster then in a solid where there is almost no space)
Pressure = total force/total area
Total force = 660 Newton's
Total area:
Each leg contacts the floor with an area of πr^2=π(0.025m)^2=0.002m^2.
Total contact area for all 3 legs = 0.006 m^2.
Pressure = (660N) / (0.006 m^2)
= 110,000 N/m^2 = 110,000 Pascal's.
