if you had a small diameter spring and made pulses, then got a different diameter spring, with the same tension and same length of the spring
A) what makes this spring act differently as a medium?
B) What change in tension would make the pulses on this spring have the same velocity as the original spring.
C) What are two ways to affect the speed of a wave?
Their motions have equal periods, but the radius of skater A's circle is half that of skater B's circle. Evaluate the ratio of the magnitudes of the forces acting on each skater?
A uniform rod of mass m and length l is kept vertical with the lower end clamped. What wil be the linear speed of the free end at this instant
