DIVIDE THEN MUTPLY THEN YOU AEMPLY SUCK
Answer:
Explanation:
in some reactions we see this as a change in the temperature. ... The study of energy changes (particularly heat) in chemical reactions is known as ... When a chemical reaction occurs, bonds in the reactants break, while new bonds form in the product. ... Physical changes can also be classified as exothermic or endothermic.
I know the answer,I just learned this,U measure it by hertz
Answer: the correct answer is 7.8026035971 x 10^(-13) joule
Explanation:
Use Energy Conservation. By ``alpha decay converts'', we mean that the parent particle turns into an alpha particle and daughter particles. Adding the mass of the alpha and daughter radon, we get
m = 4.00260 u + 222.01757 u = 226.02017 u .
The parent had a mass of 226.02540 u, so clearly some mass has gone somewhere. The amount of the missing mass is
Delta m = 226.02540 u - 226.02017 u = 0.00523 u ,
which is equivalent to an energy change of
Delta E = (0.00523 u)*(931.5MeV/1u)
Delta E = 4.87 MeV
Converting 4.87 MeV to Joules
1 joule [J] = 6241506363094 mega-electrón voltio [MeV]
4 mega-electrón voltio = 6.40870932 x 10^(-13) joule
4.87 mega-electrón voltio = 7.8026035971 x 10^(-13) joule
Explanation:
<em>Given</em>
<em>Work </em><em>(</em><em>W</em><em>) </em><em> </em><em>=</em><em> </em><em>9</em><em>5</em><em>0</em><em> </em><em>J</em>
<em>time </em><em>(</em><em>t</em><em>) </em><em> </em><em>=</em><em> </em><em>5</em><em> </em><em>sec</em>
<em>Power </em><em>(</em><em>P) </em><em> </em><em>=</em><em> </em><em>?</em>
<em>We </em><em>know </em>
<em>p </em><em>=</em><em> </em><em>w/</em><em>t</em>
<em> </em><em> </em><em> </em><em>=</em><em> </em><em>9</em><em>5</em><em>0</em><em>/</em><em>5</em>
