In the process of nuclear fusion, large amounts of energy, at temperatures of approximately 120 million kelvin, are required to join two nuclei into a single, heavier nucleus. why does the process of fusion require so much energy in order to take place?
a) to allow the electrons to enter the nucleus
b) to remove the electrons from the electron clouds
c) to cause the two nuclei to slow down and find each other
d) to overcome the electrostatic forces between opposing nuclei

Part a constants huck finn walks at a speed of 0.60 m/s across his raft (that is, he walks perpendicular to the raft's motion what is huck's velocity (speed and direction) relative to the river bank? express your answer to three significant figures and include the appropriate units. relative to the shore)

In an experiment, how can i change human errors? be specific.

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
