The experimental strings are not ideally rigid, and have some elasticity: the stronger the pull, the bigger the elongation. What is the effect on the transverse wave velocity as compared to the transverse wave velocity in an ideal string

Initially, a particle is moving at 5.33 m/s at an angle of 37.9° above the horizontal. two seconds later, its velocity is 6.11 m/s at an angle of 54.2° below the horizontal. what was the particle's average acceleration during these 2.00 seconds in the x-direction (enter first) and the y-direction?

Most short-period comets do not have randomly oriented orbits because

Ionic compounds can be readily dissolved in water because the high dielectric constant of water screens and decreases the force between the oppositely charged ions.
