Answer:
v = 12.8 m/s
Explanation:
Applying the law of conservation of energy:
where,
m₁ = mass of baseball = 149 kg
m₂ = mass of catcher = 57 kg
u₁ = initial speed of ball = 17.7 m/s
u₂ = initial speed of catcher = 0 m/s
v₁ = v₂ = v = final speed of ball and the final speed of catcher = ?
both are same because ball is in hands of cathcer in the final state.
Therefore,
<u>v = 12.8 m/s</u>
Nuclear power
because thermal energy is obtained via the nuclear fuel.
Answer:
Nuclear binding energy is the energy required to split a nucleus of an atom into its component parts: protons and neutrons, or, collectively, the nucleons. The binding energy of nuclei is always a positive number, since all nuclei require net energy to separate them into individual protons and neutrons.

Answer:
I can only explain using the formula
Explanation:
v=f
v is velocity
f is frequency
lamda is wavelength ( I don't have the symbol)
therefore velocity is the product of frequency and wavelength
And since period is the inverse of frequency;
Period (T)=1/f
so we can have v=lamda/T
That's what I think
