Check out how large the Sun appears when the Moon is one pixel wide using this online model of the solar system. Unlike this website, we used one proportion, or scale factor, for the planets’ diameters and another scale factor for the planets’ distances from the Sun. Why do you think it is common to use two different methods of scaling for the planet’s diameters and distances when creating a model?

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.
