The sun orbits the center of the milky way galaxy once each 2.60 x 108 years, with a roughly circular orbit averaging 3.00 x 104 light years in radius. (a light year is the distance traveled by light in 1 y) part (a) calculate the centripetal acceleration of the sun in its galactic orbit in m/s2 numerica numeric value is expected and not an expression. part (b) calculate the average speed of the sun in its galactic orbit in m/s. numeric : a numeric value is expected and not an expression.
answer; ///i do believe that the correct answer is ; ///(physical change); /////
matter that emits no light at any wavelength is called dark matter.
the net force vector will be in forward direction. therefore the correct answer is option (d).
since the skier pushes himself along the snow on flat ground and he feels air resistance, he will only feels air resistance when he starts moving (unless wind is blowing in opposite direction). the net force vector is dependent on the amount of force applied by the skier here we assume that skier continues to move in forward direction. the net force vector will act in the direction of acceleration, since the skier continues to move in the forward direction, therefore the net force vector will also point in the forward direction.
