Astudent is collecting data about the hardness of mineral samples. he wants to display the hardness of each sample on a scale of 1 to 10. the best choice for displaying his data would be

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.

True or false graphs must include scales that increase by the same amount
