The correct answer is in red, but I need help understanding why
that is the correct answer.
A standing wave is oscillating at 690 Hz on a string, as shown in the 8. 60 cm figure. What is the wave speed? 410 m/s B 280 m/s C) 140 m/s A) 210 m/s A mass oscillates at the end of a spring. If you double both the mass and the spring constant, the period of 9. oscillation is unchanged. B))False A)...

Can you please solve? The correct answer is sqrt(4gR) You whirl a ball of mass m in a fast vertical circle on the end of a light string of length R. At the bottom of the circle, the tension in the string is five times the ball's weight. The ball's speed at this point is given by....? Can you draw the free body diagram in your explanation and fully explain how to find tension?
