MCQ
Fusion reaction takes place at high temperature because 
  • A
    nuclei break up at high temperature
  • B
    atoms get ionised at high temperature
  • kinetic energy is high enough to overcome the coulomb repulsion between nuclei
  • D
    molecules break up at high temperature

Answer

Correct option: C.
kinetic energy is high enough to overcome the coulomb repulsion between nuclei
c
Extremely high temperature needed for fusion make kinetic energy large enough to overcome coulomb repulsion between nuclei.

One ice skater of mass $m$ moves with speed $2v$ to the right, while another of the same mass $m$ moves with speed $v$ toward the left, as shown in figure $I$. Their paths are separated by $a$ distance $b$. At $t = 0$, when they are both at $x = 0$, they grasp a pole of length $b$ and negligible mass. For $t > 0$, consider the system as a rigid body of two masses $m$ separated by distance $b$, as shown in figure $II$. Which of the following is the correct formula for the motion after $t = 0$ of the skater initially at $y = b/2?$
