3. Millie loves to go to the park and play on the swings. She gets on her favorite swing and she goes back and forth one time in 2.8 seconds. What can we determine from this question? Select all that apply. If Millie's frequency increases, the period will decrease.

Millie's frequency is 0.36 Hz.

Millie's swing period is 0.36 seconds.

Millie's wavelength is 20 inches.

Millie's swing period is 2.8 seconds.​

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.

What is the coefficient of kinetic friction μk between the block and the tabletop?
