Tan = opposite/adjacent
= 20/15
=4/3
Answer:

Explanation:
To find the rotational kinetic energy you first calculate the angular acceleration by using the following formula:

F: force applied
R: radius of the wheel
I: moment of inertia

With this value you calculate the angular velocity:

you calculate how many radians the wheel run in 5.0m


Next, you use the formula for the rotational kinetic energy:

For the transnational kinetic energy you use the following equation:
(net work equals the change in the kinetic energy).
By replacing the you obtain:

Finally, the ratio between translational rotational kinetic energy is:

hence, translational kinetic energy is three times the rotational kinetic energy.
They combine as atoms, and separate as ions. When sodium and chlorine atoms come together to form sodium chloride (NaCl), they transfer an electron. The sodium (Na) atom transfers one electron to the chlorine (Cl) atom, so that they both have full outer shells. ... When this happens, the atom is called a positive ion.
A. Is the correct answer.
