Lucas measured the volume of two different solutions. Each solution had a volume of 27.5 mL. Which of the following is a valid hypothesis Lucas could make about the solutions?
or similar to that of sulfur
a- the two solutions give off an odor similar to that of sulfur. b-the solutions would have a total volume of 55mL if they were combined c-what are the chemicals properties of the two solutions? d- do the solutions have identical molarities?

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.
