1. Vertically oriented circular disks have strings wrapped around them. The other ends of the strings are attached to
hanging masses. The diameters of the disks, the masses of the disks, and the masses of the hanging masses are
given. The disks are fixed and are not free to rotate. Specific values of the variables are given in the figures.

See the answers and explanation below

Explanation:

To solve this problem, we must have the full description of this problem, by doing an internet search we can find a problem with the same description and with the respective question.

Description of the problem

"Vertically oriented circular disks have strings wrapped around them. The other ends of the strings are attached to  hanging masses. The diameters of the disks, the masses of the disks, and the masses of the hanging masses are

given. The disks are fixed and are not free to rotate. Specific values of the variables are given in the figures. Rank these situations, from greatest to least, on the basis of the magnitude of the torque on the disks. That is, put first the situation where the disk has the greatest torque acting on it and put last the situation where the disk has the least torque acting on it."

For case D

T = (20/2)*800 = 8000 [g-cm]

For case A

T = (20/2)*500 = 5000 [g-cm]

For case C

T = (10/2)*500 = 2500 [g-cm]

For case B

T = (10/2)*200 = 1000 [g-cm]

In this way it has been organized from the largest to the smallest torque present in each of the cases.

from 1609, galileo galilei used the recently invented telescope to observe the sun, moon and planets. he saw the mountains and craters of the moon, and for the first time revealed the planets to be worlds in their own right. galileo also provided strong observational evidence that planets orbited the sun.

his discoveries about the moon, jupiter's moons, venus, and sunspots supported the idea that the sun - not the earth - was the center of the universe, as was commonly believed at the time.galileo turned his gaze toward venus, the brightest celestial object in the sky - other than the sun and the moon.
