Two objects are moving downward at a speed of 3 cm/s. Object A has a mass of 2kg and object B has a mass of 1kg. You want both objects to move to the left at a speed of 3 cm/s 1. In what direction should you exert the forces that will make the desired change?

2. Describe what strength force or forces would be needed to cause the desired velocity change.

At what point the certain object feels zero garvitational force between earth and the moon. take the required information from the book.required: distance away from earth or moon

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

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.
