Part B. How does your answer compare to the density of water?

Answer #1

A satellite of mass 3.00 x 104 kg is placed in orbit
around Jupiter. The mass of Jupiter is 2.90 x 1027 kg.
The distance between the satellite and the centre of Jupiter is
9.24 x 107 m.
Determine the force of gravitational attraction between the
satellite and Jupiter.
One of the moons of Jupiter is Io. The distance between the
centre of Jupiter and the centre of Io is 5.22 x 108 m.
If the force of gravitational attraction...

A square gate is used to prevent seawater (density = 1027
kg/m^3) intrusion into a sewer main. The depth of
water(density=1000 kg/m^3) in the sewer is 1.3 m, and the top and
bottom of the gate 0.3m and 0.6m below the surface in the sewer .
If the tide rises and falls such that the minimum and maximum
heights of seawater are 2.6m and 3m . Calculate the force required
at the base of gate to ensure there is no...

A uniform cylindrical turntable of radius 1.90 m and mass 30 kg
rotates counterclockwise in a horizontal plane with an initial
angular speed of 4π rad/s. The fixed turntable bearing is
frictionless. A lump of clay of mass 2.25 kg and negligible size is
dropped onto the turntable from a small distance above it and
immediately sticks to the turntable at a point 1.80 m to the east
of the axis.
a.) Find the resulting angular speed of the clay...
