A centrifuge in a biology laboratory rotates at an angular speed of 3,400 rev/min. When switched off, it rotates 48.0 times befo
IgorLugansk [536]

Answer:

- 210 rad/s²

Explanation:

n = frequency of rotation = 3400/60 = 170/3 per sec.

angular velocity  ω ( 0 ) at time 0  = 2π n = 2π x 170/3

angular velocity at time t = ω(t) = 0

now, ω²( t) = w²(o) + 2α Φ ( α = angular acceleration and Φ = angular displacement) = 2π x 48 rad.

0 = ( 2π x 170/3 )² + 2α x 48 x 2π

α = - (2π x 170 x 170 )/ (3 x 3 x 2 x 48 ) = 210 rad / s²

Which object is I’m equilibrium?
IrinaK [193]

Equilibrium is a state of no motion. If donuts are on the table, they are in equilibrium. Literally anything that is NOT moving relative to the earth is in equilibrium. The chair is in equilibrium, the table is in equilibrium, the cookies are in equilibrium, and so on.

larisa [96]
According to Newton's third law, the foot and the soccer ball<span> exert equal and opposite </span>forces<span> on each other. An </span>action force<span> and the </span>reaction force<span> that results are called a </span>force<span> pair. Newton's third law states that the </span>forces<span> in a </span>force<span> pair are equal in size, but opposite in direction.
