Answer:
Hey
on August 6, 1945, the atomic bomb was released. the only remains of the poor people in Hiroshima were the shadows of the last place they stood.
The energy that was released by the atomic bomb was transferred by nuclear fission (The processes at which atoms split and give off energy).
In the core of the sun, the process is different from that of fission. it is called nuclear fusion (the process in which atoms [of hydrogen] are smashed together into helium and release tremendous amounts of energy).

If you burn it a really long, the. It gets smaller, which is a physical change. Hope this helps!
Answer:
2 x 10^-5 Tesla
Explanation:
Kinetic energy, K = 57 micro electron volt = 57 x 1.6 x 10^-25 J
Length of arc = 2 mm
Angle turn = 90° = π/2 = 1.57 radian
Let the strength of magnetic field is B.
mass of electron, m = 9.11 x 10^-31 kg
K = 1/2 x mv²
where, v be the velocity of electron
57 x 1.6 x 10^-25 = 0.5 x 9.11 x 10^-31 x v²
v = 4474.59 m/s
radius = arc length / angle = 2 / 1.57 = 1.27 mm
By the formula for the radius
r = mv / Bq
B = mv / qr
B = (9.11 x 10^-31 x 4474.59) / (1.6 x 10^-19 x 1.27 x 10^-3)
B = 2 x 10^-5 tesla
Thus, the magnetic field is 2 x 10^-5 Tesla.
B might be the answer hope this helps
