<span>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.</span>
We could determine the acceleration using this formula

Given from the question v₀ = 23 m/s, v₁ = 0 (the car stops), t = 5 s
plug in the numbers



a = -4.6
The acceleration is -4.6 m/s²
Answer:
+300N-130N=170N
Explanation:
because two forces in opposite direction one take +and the other takes -
Correct Question:-

Given :-



To find:-


Solution:-
we know :-


So:-



























Answer:
The frequency of the photon is
.
Explanation:
Given that,
Energy
We need to calculate the energy
Using relation of energy

Where,
= energy spacing


Put the value of h into the formula


Hence, The frequency of the photon is
.
