You will need the following items: a rope about 10 to 20 meters long, a meter or yard stick, a watch that records seconds. Tie one end of the rope to a doorknob or other secure object at about waist height. Have your helper take one end of the rope and whip it up and down, while you watch.
What type of wave was created? How do you know?
Estimate the wavelength of the wave produced.
Estimate the frequency of the wave produced.
This is most easily estimated by counting the number of waves that pass the measuring device within a particular time interval as measured on your watch, or by counting the number of times the hand is shaken up and down.
Compute the velocity of your wave. Lay a slinky on a table and secure one end to one edge of the table. Stretch the slinky across the length of the table and give the free end a quick push in the direction of the secured end. Answer the questions below.

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.
