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.

Acricket ball of 70g moving with a velocity of 0.5 m/s is stopped by a player in 0.5s what is the force applied to stop the ball

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
