According to newton first law of motion an object at rest must stay at rest, an object at motion must stay in motion. So when you are in a car driving and then you slam on the break you body moves forward towards the windshield and that because an object such as you want to be in motion because you set it on motion. Thats the same as the dummies seat belts and air bags, when a car is in a car crash it testing its seat belts and the airbags if they are fast and strong enough to stop you from going forward. Hope this helps
I don’t see the diagram :)?
Answer:
Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy

13 g —> 0.013 kg
KE = 1/2(m)(v)^2
KE = 1/2(0.013)(8.5)^2
KE = 0.47 J
Answer:
+131Joules
Explanation:
Energy can be expressed using below expresion.
ΔE = (q + w).........eqn(1)
q will be + be if heat is gained hence, q= 240 J
work "w" will be - ve if work is done by the system, hence w= -109 J
Then substitute into eqn(1)
Change in Internal energy=
= (240 -109 )
= +131J
