The center of mass of a 0.3 kg (non-uniform) meter stick is located at its 46-cm mark. what is the magnitude of the torque (in nm) due to gravity if it is supported at the 25-cm mark? (use g = 9.79 m/s2)

suppose that a meter stick is balanced at its center(50 cm mark). a 0.27 kg mass is then positioned at the 20 cm mark. at what cm mark must a 0.30 kg mass be placed to balance the 0.27 kg mass?

Agroup of students is studying convection currents. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other in an area with warm air. after 10 minutes, the balloons are released from a height of 1 meter. which of the following do the students most likely observe? question 2 options: the balloons rise at the same rate. both balloons are the same size. the ballons both rise. the cold ballon is larger than the warm balloon. the cold balloon expands and rises. the warm balloon shrinks and sinks. the warm balloon expands and rises. the cold balloon shrinks and sinks.
