The choices for this question can be found elsewhere and as follows:
short hill.
tall hill.
tightly coiled spring.
<span>stretched-out spring.
</span>
I think the best answer is the third option. A high amplitude sound wave can best be compared to a tightly coiled spring. <span>A </span>high<span> energy </span>wave<span> is characterized by having a </span><span>high amplitude.</span>
When a nucleus of Ra (Radium) decays, it emits an alpha particle and becomes a Rn (Radon) nucleus, as described in the (Fig. 1 – Alpha decay). In general, during alpha decay the atomic number (Z) is reduced by two units and the mass number (A), by four units.
Sodium becomes positively charged because it has lost an electron
D) they will all hit the ground at the same time. In the context that there is no air resistance and each object is in free fall, then they will have the same acceleration rate.
