**Answer:**

The resulting coordinate is

**Explanation:**

From the question we are told that

The mass of the first dice is

The mass of the second dice is

The mass of the third dice is

The coordinate of the first dice is

The coordinate of the second dice is

The coordinate of the third dice is

Generally the resulting coordinate of the center of mass of the dice in the x-axis is mathematically evaluated as

i.e the summation of the moments about their x-axis divided by the magnitude of their masses

substituting values

Generally the resulting coordinate of the center of mass of the dice in the y-axis is mathematically evaluated as

Thus the resulting coordinate is

**Answer:**

Transverse

**Explanation:**

There are two types of waves, depending on the direction of the oscillation:

- Transverse wave: in a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave - examples of transverse waves are electromagnetic waves

- Longitudinal wave: in a longitudinal wave, the direction of the oscillation is parallel to the direction of motion of the wave - examples of longitudinal waves are sound waves

Radio waves are a type of electromagnetic waves - consisting of oscillations of electric and magnetic field that propagate in a vacuum at the speed of light - so they are an example of transverse wave.
