<span>If
you notice that two waves combine and a part of the resulting wave has
less light intensity than either of the individual waves, you're
observing destructive interference. </span><span>Destructive interference happens when the two waves that combine have amplitudes with opposite signs,which results in subtraction- combined wave with a lower amplitude.</span>
The answer & explanation for this question is given in the attachment below.
La densidad del metal disminuye a medida que se calienta . Piense en el agua . Cuando hace frío , se convierte en hielo , lo cual es muy densa . Cuando hace calor , se evapora en gas , que no es denso.

No, i think centripetal force can never do work on object
Work = force x distance
Centripetal force can create the force, but there will never be any effect on the distance, which make it became 0
Hope this helps
The first one: A. Decreases one half of the original weight.
The second one: D. a change in the objects linear velocity.
