Answer:
a) , b)
Explanation:
The magnitude of torque is a form of moment, that is, a product of force and lever arm (distance), and force is the product of mass and acceleration for rotating systems with constant mass. That is:
Where is the angular acceleration, which is constant as torque is constant. Angular deceleration experimented by the unpowered flywheel is:
Now, angular velocities of the unpowered flywheel at 50 seconds and 100 seconds are, respectively:
a) t = 50 s.
b) t = 100 s.
Given that friction is of reactive nature. Frictional torque works on the unpowered flywheel until angular velocity is reduced to zero, whose instant is:
Since , then the angular velocity is equal to zero. Therefore:
<span>In a correctly balanced chemical equation, there are exactly the same number of atoms for each element found on both side of the equation (that is, in the reactants and the products).
No new atoms were made. None were destroyed. Matter was conserved.</span>
The answer would be, "Sulfur Dioxide".
So Neon ( Ne) is the correct answer.
