A satellite was launched in order to observe the Saturn. At the moment the distance between the satellite and the Saturn was

10 km with an attractive force 10,000 N. While after 20

seconds, the distance decreased to 5 km, what is the force

then (in N)?

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.

The photo above shows oil and vinegar in a pitcher. the top make a claim about about the density of the vinegar compared to the density of the oil summarize the evidence to support the claim and explain your reasoning
