Answer:
Nuclear fusion reactions produce more energy.( basic difference)
Explanation:
Nuclear fusion reactions are different from nuclear fusion reactions :- In nuclear fission one heavy and unstable nuclear breaks into two parts(smaller) and produce energy( very high energy than normal reaction). whereas in nuclear fusion two small and unstable nuclei fuse and produce very high amount of energy( even higher than nuclear fusion).
The answer is C. Along the magnetic field lines

Answer:
α = 2T/mR
Explanation:
We know torque τ = Iα = TR where I = rotational inertia and α = linear (tangential) acceleration, T = tension in string and R = radius of cylinder.
Now T = tension in string and I = (1/2)mR²
So τ = Iα = TR
α = TR/I
substituting the values of the variables, we have
α = TR/(1/2)mR²
α = 2TR/mR²
α = 2T/mR
So, the linear acceleration of the person's hand on time, t is α = 2T/mR
