Give an argument of a formation of a wave on a stretched string. tell what happens when a wave pulse hits the end of a string for extreme cases, a string being attached to a mass and friction free ring on a rod. develop a disscusion on wave in a particular physical system.

In the first law of thermodynamics, triangle e=q-w, what does q stand for

Describe cytokinesis in plants and animals. in animals: in plants.

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
