Ameteorite approaching a planet of mass m collides with an automatic space station orbiting the planet in a circular trajectory of radius r. the mass of the station is ten times as large as the mass of the meteorite . as a result of the collision, the meteorite sticks with the station which goes over to a new orbit with the minimum distance r/2 from the planet. speed of the meteorite just before it collides with the space station is

Iflow from a warmer object to a cooler object until both objects are the same temperature what am i?

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
