Answer:
0.092 J
Explanation:
Rotational kinetic energy is:
RE = ½ Iω²
where I is the moment of inertia and ω is the angular speed.
For a solid cylinder, I = ½ mr².
RE = ½ (½ mr²) ω²
RE = ¼ mr²ω²
Convert ω from rpm to rad/s.
33.4 rev/min × (2π rad/rev) × (1 min / 60 s) = 3.50 rad/s
Plug in values and solve:
RE = ¼ (3.0 kg) (0.10 m)² (3.50 rad/s)²
RE = 0.092 J
Answer: Eating
Explanation: Pasta is a food so people eat it.
Answer:
Explanation:
Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave. Patterns can be used to identify cause and effect relationships.
Mechanical waves are those waves that require a material medium for propagation.
<h3>What are mechanical waves?</h3>
Generally, we define a wave as a disturbance along a medium which transfers energy. It then follows that waves move energy from one point to another.
Waves can be classified as;
- Mechanical waves
- Electromagnetic waves
Mechanical waves are those waves that require a material medium for propagation such as sound, and waves on a strings.
