32.66 m/s
Explanation:
The potential energy stored in the spring will impart kinetic energy into the dart:
substitute the values:
Answer: <u><em>C. Steel</em></u>
Explanation: <em><u>When a sound wave travels through a solid body consisting</u></em>
<em><u /></em>
<em><u>of an elastic material, the velocity of the wave is relatively</u></em>
<em><u /></em>
<em><u>high. For instance, the velocity of a sound wave traveling</u></em>
<em><u /></em>
<em><u>through steel (which is almost perfectly elastic) is about</u></em>
<em><u /></em>
<em><u>5,060 meters per second. On the other hand, the velocity</u></em>
<em><u /></em>
<em><u>of a sound wave traveling through an inelastic solid is</u></em>
<em><u /></em>
<em><u>relatively low. So, for example, the velocity of a sound wave</u></em>
<em><u /></em>
<em><u>traveling through lead (which is inelastic) is approximately</u></em>
<em><u /></em>
<em><u>1,402 meters per second.</u></em>

Answer: Nuclear energy
Explanation:
Nuclear energy (also called atomic energy) is the energy found in the nucleus of an atom.
This energy is released spontaneously (within the stars and the sun) or artificially (in nuclear reactors built by humans) in nuclear reactions, which are divided into two types:
-Fission (separation of the components of the atom nucleous)
-Fusion (joining two light nuclei to form a heavier nucleous)
In the case of the Sun, the nuclear reactions that occur are due fusion, in which the hydrogen is converted into helium.
Answer:
endothermic reactions
Explanation:
An instant cold pack is a device that consists of two bags; one containing water, inside a bag containing ammonium nitrate, calcium ammonium nitrate or urea. When the inner bag of water is broken by squeezing the package, it dissolves the solid in an endothermic reaction.
It would be asexual because only one parent is involved and it is a clone of the parent plant
