Abdou was explaining to a classmate that graphite is a good lubricant

Physics

The fact that the layers of graphite are held together by only weak Van der Walls forces implies that they can slide over each other.

<h3>Why is graphite a solid lubricant?</h3>

We know that graphite is composed of layers. These hexagonal layers are held together by weak Van Der Walls forces and as such are able to slide over each other. The carbon atom in each layer are held together by strong covalent bonds.

The fact that the layers of graphite are held together by only weak Van der Walls forces implies that they can slide over each other and as such make the graphite fluid.

Thus, the image that shows these layers of graphite is attached to this an answer

what is the property of an object due to its mass by which it resists any change in its position unless overcome by force ?
UkoKoshka [18]

Answer:

Mass as a Measure of the Amount of Inertia

All objects resist changes in their state of motion. All objects have this tendency - they have inertia.

Explanation:

hope this helps

Carole is very tired and makes coffee. why would newton say that she must use her hand to put up the cup
Marat540 [252]
<span>newton say that she must use her hand to put up the cup because the work is equal to force times it distance, that is in the same direction of the force applied. if carole used her hand to put up the cup, then he is not applying any work because the displacement is not in the same direction of the force</span>

Label each statement according to whether it refers to AC, DC, both, or neither.a. The current is always constant in these types
umka21 [38]

Answer:

1 DC

2 DC

3 DC

4 AC

5 DC

Explanation:

AC means alternating current this type of current is not constant I.e time varying

This type of current is being supplied from power lines

DC means direct current and flows at a constant direction. This type of current is being supplied from batteries.

A wheel rotates without friction about a stationary horizontal axis at the center of the wheel. A constant tangential force equa
ivann1987 [24]

Answer:

The moment of inertia of the wheel is 0.593 kg-m².

Explanation:

Given that,

Force = 82.0 N

Radius r = 0.150 m

Angular speed = 12.8 rev/s

Time = 3.88 s

We need to calculate the torque

Using formula of torque

\tau=F\times r

\tau=82.0\times0.150

\tau=12.3\ N-m

Now, The angular acceleration

\dfrac{d\omega}{dt}=\dfrac{12.8\times2\pi}{3.88}

\dfrac{d\omega}{dt}=20.73\ rad/s^2

We need to calculate the moment of inertia

Using relation between torque and moment of inertia

\tau=I\times\dfrac{d\omega}{dt}

I=\dfrac{I}{\dfrac{d\omega}{dt}}

I=\dfrac{12.3}{20.73}

I= 0.593\ kg-m^2

Hence, The moment of inertia of the wheel is 0.593 kg-m².
