**Answer:**

If you have a parental figure or guardian ask them for assistance. Contact a lawyer if you are willing to take action against your attacker.

Both are metals and are good conductors of electricity and heat.

**Answer:**

0.89534 kgm²

**Explanation:**

= Final angular velocity = 12.9 rad/s

= Initial angular velocity = 5.5 rad/s

= Initial moment of inertia = 2.1 kgm²

= Final moment of inertia

As there is no external torque the angular momentum is conserved

**The final moment of inertia is 0.89534 kgm²**

**Explanation:**

To find the answer use the equation speed of light=wavelength multiplied by frequency (c=lambda*f) by substituting the value for the frequency the the speed of light

**Answer:**

What evidence supports their claim.

**Explanation:**

In the end, all that really matters in an experiment, is what scientific evidence supports the claim being made.
