Answer:

ωB = 300 rad/s

ωC = 600 rad/s

Explanation:

The linear velocity of the belt is the same at pulley A as it is at pulley D.

vA = vD

ωA rA = ωD rD

ωD = (rA / rD) ωA

Pulley B has the same angular velocity as pulley D.

ωB = ωD

The linear velocity of the belt is the same at pulley B as it is at pulley C.

vB = vC

ωB rB = ωC rC

ωC = (rB / rC) ωB

Given:

ω₀A = 40 rad/s

αA = 20 rad/s²

t = 3 s

Find: ωA

ω = αt + ω₀

ωA = (20 rad/s²) (3 s) + 40 rad/s

ωA = 100 rad/s

ωD = (rA / rD) ωA = (75 mm / 25 mm) (100 rad/s) = 300 rad/s

ωB = ωD = 300 rad/s

ωC = (rB / rC) ωB = (100 mm / 50 mm) (300 rad/s) = 600 rad/s

Is there a pattern to the volcano distribution around the plant?
alexira [117]
Hi there!

Typically volcanoes are found alongside tectonic plate boundaries and in that sense could be considered a pattern. One of the most famous is 'The Ring of Fire' which is a ring of volcanoes in the pacific ocean along the pacific plate boundary.

What would happen if there was no condensation stage in the water cycle?
slavikrds [6]
Without condensation, the water vapor could not turn into clouds and liquids then which means it could not fall back down through things like rain or hail. Eventually, all water on earth would then become water vapor and we wouldn't have any water in liquid form.
