Suppose you were to make a three-dimensional model of magnetic force using magnetic field lines and a magnet. Which two characteristics might
your model have?
O A. Arrows on the field lines point from the magnet's north pole to its
south pole.
O B. The field lines exist only at the top and the bottom of the magnet.
OC. The field lines do not cross paths as they go from one pole of the
magnet to the other.
O D. The field lines near the magnet are far apart.

Ablock of mass 1.5 kg slides down an inclined plane that has an angle of 15. if the inclined plane has no friction and the block starts at a height of 3 m, how much kinetic energy does the block have when it reaches the bottom? acceleration due to gravity is g = 9.8 m/s2. a. 6.8 j b. 50.9 j c. 0 j d. 44.1 j

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.
