When a constant force acts upon an object, the acceleration of the object varies inversely with its mass. When a certain constan
t force acts upon an object with mass 7 kg, the acceleration of the object is 8 m/s^2. If the same force acts upon another object whose mass is 4 kg, what is this object's acceleration?
Because there are a total of 13 balls and 4 of them are red, if you are drawing out randomly you have to draw a minimum of 11 balls to guarantee that at least two red balls are among them
