Monique is investigating packing in crystalline solids. She wants to determine how many atoms can be packed into a set volume for each of several configurations. She decides to use magnets to model a solid that is made up of two different elements. Atoms of one element have greater diameters than atoms of the other element. Which of the sets of magnets shown below would Monique need in order to make a model for her investigation? Assume the images are roughly to scale.​

Because light travels in a straight line and casts a shadow, isaac newton hypothesized that light is

An atom that has gained or lost electrons is called an _

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.
