    Does Throwing an Object Downward Change Its Acceleration Due to Gravity?

    if you drop on object, it will accelerate downward at a rate of g=9.8m/s^2 if you throw it downward instead, it's accerleration (absence of air resistance) will be :confused: a) greater than 9.8 m/s^2 b) unable to determine c) 9.8 m/s^2 d) less than 9.8 m/s^2

    Surface area of a sphere problem

    Sphere 1 has surface area A1 and volume V1, and shere 2 has surface area A2 and volume V2. If the radius of shere 2 is four times the radius of shere 1, what is the ratio A2/A1 of the areas?
