Ice melts when heat energy causes the molecules to move faster, breaking the hydrogen bonds between molecules to form liquid water.
Hello! Let me try to answer this :)
Thanks and please correct if there are any mistakes ^ ^
Answer:
<h3>The answer is 3.85 s</h3>
Explanation:
The time taken can be found by using the formula
![t = \frac{d}{v} \\](https://tex.z-dn.net/?f=t%20%3D%20%20%5Cfrac%7Bd%7D%7Bv%7D%20%20%5C%5C%20)
d is the distance covered
v is the velocity
From the question we have
![t = \frac{50}{13} \\ = 3.846153...](https://tex.z-dn.net/?f=t%20%3D%20%20%5Cfrac%7B50%7D%7B13%7D%20%20%5C%5C%20%20%3D%203.846153...)
We have the final answer as
<h3>3.85 s</h3>
Hope this helps you
Answer: An alpha-particle is identical to the nucleus of a normal (atomic mass four) helium atom i.e. a doubly ionised helium atom. Alpha particles (also termed alpha radiation or alpha rays) was the first nuclear radiation to be discovered, beta particles and gamma rays were identified soon after.
