The correct answer is 2 N/cm, I take k12 and that was the correct answer
Hertz, which is a unit for frequency (f), also means 1/second. Hence, the speed (S) of wave is the product of its wavelength (n) generated per second (frequency). The speed of the given wave above is,
S = nf ; S = (45 m) x (9 / s) = 405 m/s
Hence, the speed of the wave is 405 m/s.
Answer:
Nuclear Fusion
Explanation:
Nuclear fusion is the nuclear reaction in which two lighter nucleus combine to form a larger more stable nucleus with the release of energy.
²₁H + ¹₁H ⇒ ³₂He + energy
In this case, a hydrogen atom reacts with a deuterium atom to produce a helium atom and energy.
Since two smaller atoms combine to produce a larger atom, nuclear fusion occurs.
