a steel ring with a hole having area of 3.990 cm2 is to be placed on an aluminum rod with crosssectional area of 4.000 cm2. both rod and ring are initially at a temperature of 35.0°c. at what common temperature can the steel ring be slipped onto one end of the aluminum rod?

divide the right side by the left side

0.024÷1.2=0.02 for example

the diagram which shows forces as either balanced = same speed or unbalanced = accelerarting

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

hope that !                                         : )
