Well,

When an object's velocity changes, we call it acceleration.

Acceleration: The time rate of change in an object's velocity

Starting from rest, a disk rotates about its central axis with constant angular acceleration. In 5.00 s, it rotates 14.8 rad. Du
11Alexandr11 [23.1K]

Answer:

Explanation:

Given:

Initial θ = 0 rad (from rest)

Final θ = 14.3 rad

Time, t = 5 s

B.

Angular velocity, w = dθ / dt

= (14.3 - 0)/5

= 2.86 rad/s

A.

Acceleration, ao = dw/dt

Initial angular velocity, wi = 0 rad/s (from rest)

Final angular velocity, wf = 2.86 rad/s

a = (2.86 - 0)/5

= 0.572 rad/s^2

Resistance is seen as part of ______________--- how a person understands his or her being and relationship to the world at large
aleksley [76]

Answer:

The self and world construct

Explanation:

in physics

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.

Self psychology views resistances as protecting a vulnerable self. Resistances are seen as efforts to maintain levels of organization that patients have achieved within the context of their traumatic life situation.

What is the average velocity of a train moving along a straight track if its displacement is 192 m was during a time period of 8
Alex

Answer:

The average velocity of a train moving along a straight track if its displacement is 192 m was during a time period of 8.0 s is 24 \frac{m}{s}.

Explanation:

Velocity ​​is a physical quantity that expresses the relationship between the space traveled by an object and the time used for it. Then, the average velocity relates the change in position to the time taken to effect that change.

velocity=\frac{displacement}{time}

Velocity considers the direction in which an object moves, so it is considered a vector magnitude.

In this case, the displacement is 192 m and the time period is 8 s. Replacing:

velocity=\frac{192 m}{8 s}

Solving:

velocity= 24 \frac{m}{s}

<em><u>The average velocity of a train moving along a straight track if its displacement is 192 m was during a time period of 8.0 s is 24 </u></em>\frac{m}{s}<em><u>.</u></em>
