Based on the given displacement vs time graph, the object is at rest at a time interval of: B. 2 to 3 seconds

<h3>What is a displacement vs time graph?</h3>

A displacement vs time graph can be defined as a type of graph that is used to graphically represent the distance traveled (covered) or displacement experienced by an object from its starting position with respect to the time when it has started moving.

In Science, a physical object being at rest simply means that the position of the object is not changing with respect to time. Thus, both the slope and velocity of the physical object would be equal to zero when it is at rest.

Between 0 to 2 seconds on the given displacement vs time graph (see attachment), this object is traveling at a constant, positive velocity. However, at a time interval of 2 to 3 seconds the object is at rest.

nevsk [136]

Answer:

1.25 kgm²/sec

Explanation:

Disk inertia, Jd =

Jd = 1/2 * 3.7 * 0.40² = 0.2960 kgm²

Disk angular speed =

ωd = 0.1047 * 30 = 3.1416 rad/sec

Hollow cylinder inertia =

Jc = 3.7 * 0.40² = 0.592 kgm²

Initial Kinetic Energy of the disk

Ekd = 1/2 * Jd * ωd²

Ekd = 0.148 * 9.87

Ekd = 1.4607 joule

Ekd = (Jc + 1/2*Jd) * ω²

Final angular speed =

ω² = Ekd/(Jc+1/2*Jd)

ω² = 1.4607/(0.592+0.148)

ω² = 1.4607/0.74

ω² = 1.974

ω = √1.974

ω = 1.405 rad/sec

Final angular momentum =

L = (Jd+Jc) * ω

L = 0.888 * 1.405

L = 1.25 kgm²/sec

miskamm [114]
Answer:
The variable manipulated or controlled by the experimenter is called the independent variable.

Example:
If the flow velocity at the bottom of a tank is measured by varying the height of water in the tank, we are measuring velocity as a function of water height.
Therefore,
water height  =  independent variable (controlled)
velocity =  dependent variable (measured in response to water height).

Mathematically,
v = f(h)
where v =  response variable (dependent)
            h = controlled variable (independent).
