A cart of mass 2m is released from rest and slides from the top of an inclined frictionless plane with height h. Express all answers in terms of the given quantities and fundamental constants. a. Determine the speed of the cart when it reaches the bottom of the incline.

b. After sliding down the incline and across a frictionless horizontal surface, the cart collides with a bumper of a negligible mass attached to an idea spring, which has a spring constant k. Determine the distance x(m) the spring is compressed before the cart and bumper come to rest.

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.

Molybdeum(mo)orruthenium (ru)actually, elements with similar chemical properties as technetium would bemn, re, and bh. this is because elements in the same group/family (column) have similar chemical properties. elements in the same period (row) have the same number of energy levels (or shells).

During the 1800s. hope this !
