Two friction disks A and also B are brought into call when the angular velocity of disc A is 240 rpm counterclockwise and disk B i

hunterriverpei.com:

a) αA = 4.35 rad/s²

αB = 1.84 rad/s²

b) t = 3.7 rad/s²

Explanation:

Given:

wA₀ = 240 rpm = 8π rad/s

wA₁ = 8π -αA*t₁

The edge in B is:

*

*

*

The velocity in ~ the contact point is equal to:

*

*

Matching both expressions:

*

b) The time throughout which the disks slip is:

*

a) The angular acceleration of every disk is

*

C the regulation of Superposition

Explanation:

When we find fossils in ~ a specific depth us can fairly date a rock based upon the strata we uncover them. A fossil in place in bottom beds will be older 보다 the one in the topmost layer. Fossils likewise succeed one another in a definite sample according to the rule of fossil and fauna succession.

Explanation:

The atmospheric pressure at the surface ar of the planet is at maximum, it is watched that together we move away indigenous the surface ar of the earth the push decreases. As on the height of mountains the atmospheric pressure is uncovered to be low as compared to the surface ar of the earth.

It is assumed the the atmospheric pressure is caused because of hydrostatic dimensions where the alters caused by load of air are measured.
