The answer would be he will spin slower.  The bean bag is not spinning beforehand it contacts the experimenter, so (through conservation of rotational momentum) he must stock the rotational momentum mandatory to make it spin at the same degree as his lap. Consequently, he ends up spinning slower.

In that experiment, there was a moment of inertia.

<h2>Further Explanation </h2>

Moment of inertia is defined as the inertia of an object to rotate on its axis, or it can be said to be a measure of the difficulty to make an object rotate or move in a circle. The moment of inertia can also be referred to as a quantity that shows the ability of an object to maintain its angular velocity in rotational motion. The amount of moment of inertia depends on the shape of the object and the position of the object's rotational axis. Moments of inertia play a role in rotational dynamics such as a mass in basic dynamics and determine the relationship between angular momentum and angular velocity, the moment of force and acceleration of angles, and several other quantities. Although the scalar discussion of the moment of inertia, the discussion using the tensor approach allows analysis of more complex systems such as gyroscopic motion. Objects that consist of a composition of particles or smaller constituent objects, if the rotational motion, then the moment of inertia is equal to the result of the sum of all the constituent inertia.

Newton's first law reads that objects which are not given an external force (external force) will tend to maintain their state. An object tries to maintain its state which is very dependent on the moment of inertia.

The greater the moment of inertia, the object will be difficult to move. Conversely, a moment of inertia that is of little value causes objects to move easily.

The hour, minute, and second hands on a clock are 0.25 m , 0.31 m , and 0.34 m long, respectively.
sp2606 [1]

In 1 hour, the hour hand sweeps across 1/12 of the clock's face. In 40 min, the hour hand travels (40 min)/(60 min) = 2/3 of the path it covers in an hour, so a total of 1/12 × 2/3 = 1/18 of the clock's face. This hand traces out a circle with radius 0.25 m, so in 40 min its tip traces out 1/18 of this circle's radius, or

1/18 × 2<em>π</em> (0.25 m) ≈ 0.087 m

The minute hand traverses (40 min)/(60 min) = 2/3 of the clock's face, so it traces out 2/3 of the circumference of a circle with radius 0.31 m:

2/3 × 2<em>π</em> (0.31 m) ≈ 1.3 m

The second hand completes 1 revolution each minute, so in 40 min it would fully trace the circumference of a circle with radius 0.34 m a total of 40 times, so it covers a distance of

40 × 2<em>π</em> (0.34 m) ≈ 85 m

A super ball stops bouncing because A) gravity never lets it bounce. B) it loses energy due to friction. C) it cannot gain poten
AlexFokin [52]

Answer:

b

Explanation:

it loses energy due to friction because if it hits objects the objects slow it down and which causes it to start slowing down

Give an example of a measurement that is precise to the nearest tenth of a gram.
Svet_ta [14]

Answer:

So we have a measure in grams, we can start with something like:

143.523 grams.

Now we want this measurement to be precise to the nearest tenth of a gram.

The nearest tenth of a gram is the first digit after the decimal point, then the digits that come after this are not useful, because they are outside our precision range.

Then we must write our measurement as:

143.5 grams

Where the digit that came after the 5 was a 2, so we rounded down.
