a steel container full of steel is pulled upwards against an incline of 30° by a tractor the mass of steel container is 1,2 tons. the pulling force of the rope forms an angle of 15°with the incline. the coefficient of friction between the surface in contact is 0,3 calculate the tensile force in the rope​

As we gain mass the force of gravity on us increases!

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.

The geological theory that states that pieces of earth's lithosphere are in constant slow motion is the theory of plate tectonics.

The anwser is: wave a has a greater pitch and frequency.
