A constant torque is applied to a rigid wheel whose moment of inertia is 2.0 kg · m2 around the axis of rotation. If the wheel s

Jlenok [28]

Answer:

The applied torque is 3.84 N-m.

Explanation:

Given that,

Moment of inertia of the wheel is $2\ kg-m^2$

Initial speed of the wheel is 0 (at rest)

Final angular speed is 25 rad/s

Time, t = 13 s

The relation between moment of inertia and torque is given by :

$\tau=I\alpha \\\\\tau=I\times \dfrac{\omega_f}{t}\\\\\tau=2\times \dfrac{25}{13}\\\\\tau=+3.84\ N-m$

So, the applied torque is 3.84 N-m.

Which occupies mrs space, 3m cubed or 100ft cubed

Slav-nsk [51]

The question is somewhat ambiguous.

-- It's hard to tell whether it's asking about '3 cubic meters'
or (3m)³ which is actually 27 cubic meters.

-- It's hard to tell whether it's asking about '100 cubic feet'
or (100 ft)³ which is actually 1 million cubic feet.

I'm going to make an assumption, and then proceed to
answer the question that I have invented.
I'm going to assume that the question is referring to
'three cubic meters' and 'one hundred cubic feet' .

OK. We'll obviously need to convert some units here.
I've decided to convert the meters into feet.

For 1 meter, I always use 3.28084 feet.

Then (1 meter)³ = 1 cubic meter = (3.28084 ft)³ = 35.31 cubic feet.

So 3 cubic meters = (3 x 35.31 cubic feet) = 105.9 cubic feet.

That's more volume than 100 cubic feet.

When the magnets are released and begin to move, the magnetic force changes potential energy into kinetic energy;<u> option D</u>

<h3>What is magnetic force?</h3>

Magnetic force can be defined as the force of attraction or repulsion that is felt or produced between the magnetic poles and electrically charged moving particles.

Magnetic force is the force that exists due to the attractio or repulsion of objects place around the region of space where a maget exerts its force.

When a magnet is released ai a system of magnets and allowed to move it increases the kinetic eergy of the system by converting potential energy to kinetic energy.
