Two satellites are in circular orbits around a planet that has radius 9.00×106 m. one satellite has mass 68.0 kg, orbital radius 7.00×107 m , and orbital speed 4800 m/s. the second satellite has mass 84.0 kg and orbital radius 4.00×107 m .what is the orbital speed of this second satellite?

Molten iron fills a mould, which has a volume of 200 cm cubed. calculate the volume when the iron cools and solidifies. molten iron has a density of 7.0g/cm cubed. in its solid state, iron has a density of 8.0g/cm cubed.

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.
