Arigid sphere is falling from a height of 1m in a fluid of density 1000 m3/kg. the time it took to fall is 500 seconds. if the density of the sphere is 1100 m3/kg and the viscosity of the fluid is 100 cp, what is the diameter of the sphere? (a. 6.1 m , b. 0.61 m , c. 0.061 m , d. 0.0061 m)

0.00191 meter is the diameter of the sphere.

Explanation:

Velocity of the rigid sphere =

Density of the fluid =

Density of the particle=

Viscosity of the fluid =

Radius of the sphere  = r

(Terminal velocity)

r = 0.00191 m

0.00191 meter is the diameter of the sphere.

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
