Answer:
- Option D is the correct answer.
Explanation:
It is given that a 2 kg ball is traveling at a speed of 4 m/s, so we have to find its kinetic energy.
KE = 1/2 mv²
KE = 1/2 × 2×(4)²
KE = 1/2 × 2×16
KE = 16 J
<u>Some information about Kinetic Energy</u>.
Kinetic Energy is the energy an object has because of its motion. It is directly proportional to the velocity of the particle and its mass. Kinetic energy is given by,
- KE = ½mv²
- It occurs due to the motion of the particle.
- If a particle at rest position, then the kinetic energy will be zero because that particle won't be accelerating.
The answer that apply is:
<span>They carry energy
</span><span>They travel from the epicenter.
</span><span>They vibrate throughout the lithosphere.
</span>
Reason why the following the false:
<span>They move in one direction- seismic wave do not only move in a direction but spread out through the plate,that's why a large area would be affected.
</span><span>They are produced by earthquakes. - seismic waves are not produced by earthquake but the opposite,earthquake occurs due to the release of seismic wave when the ground break and vibrates.</span>
I believe the correct answer would be Tapeworm and cat
<span>The grouping of organisms based on their common descent is called evolutionary classification. Through evolution, one species has changed and become modified until it became what it is today. However, some of today's organisms have the same predecessor, which is evident if you take evolution into consideration. </span>
