**Answer:**

The new angular speed of both disks when they are rotating together is 2.311 revolutions per second.

**Explanation:**

This situation can be analyzed by the Principle of Conservation of Angular Momentum since there are no external forces and moments being exerted on the system, whose definition is presented below:

**(1)**

Where:

, - Initial and final angular speeds, measured in revolutions per second.

- Initial and final moments of inertia, measured in kilograms per square meter.

The initial and final moments of inertia of the system are, respectively:

**(2)**

**(3)**

By applying **(2)** and **(3)** in **(1)**, we obtain the following expression:

**(4)**

If we know that , then the new angular speed of both disks when they are rotating together is:

The new angular speed of both disks when they are rotating together is 2.311 revolutions per second.

**Answer:**

glass if for a good view, but for absorbing heat concrete and brick is the best

**Explanation:**

wood is not a good idea bc it can cause fires from too much heat and it absorbs less heat but all of that depends on how good the material your using

**Answer:**

%56.25

**Explanation:**

1.25^2-1^2/1^2 x 100 = 56.25
