Explain the roles of products, reactants, and limiting reactant in chemical reaction.
andreev551 [17]
The <span>roles of products, reactants, and limiting reactant are significant in order for a chemical reaction to take place. The reactants are the components that are interacted in such a way that it would eventually produce a product, while on the other hand, a limiting reactant is used to regulate the products intended to produce.</span>

What do you know in climate change?​
Degger [83]

Climate change is the reason for a lot of factors such as:

Heat-trapping Greenhouse Gases And The Earth's Climate

Greenhouse Gases

Reflectivity or Absorption of the Sun's Energy

Changes in the Earth's Orbit and Rotation

Variations in Solar Activity

Changes in the Earth's Reflectivity

Volcanic Activity

There's a lot more that I could list, but hopefully this will do.

A centrifuge rotor (hollow disk) is rotating at 10,000 rpm is shut off and brought to rest by a constant frictional torque of 1.
Y_Kistochka [10]

Answer:

The no of revolutions rotor turn before coming to rest is 1,601.1943 and time taken is equal to 19.21 seconds

Explanation:

here we know that torque = I×α

     α= angular acceleration

     I = moment of inertia of hollow disc = m×k^{2}

  given that m=4.37kg

                    k=0.0710m

           torque=1.2Nm

        w_{o}=10000\times \frac{\pi}{30} rad /s

         \alpha =\frac{torque}{I}

from the above equation we can calculate the angular acceleration of the hollow disc .

  since  w^{2}-w_o^{2} =2\alpha\theta

 from this above equation  \theta=\frac{w^{2}-w_{o}^{2}}{2\alpha }

   no of revolutions = \frac{\theta}{2\pi}  = 1,601.1943.

Now to calculate time we know that time = \frac{2\theta}{w+w_{o}}

   so upon calculating we will be getting t=19.21 seconds
