The diagram represents a chain reaction that is caused by nuclear fission.
<h3>What is a nuclear fission reaction?</h3>
A nuclear fission reaction is a reaction in which the nucleus of a larger atom is split into two or more smaller nucleus of atoms.
Nuclear fission can proceed in the form of a chain reaction in which the products of the first fission reaction are used to initiate further fission reactions.
Therefore, the diagram represents a chain reaction that is caused by nuclear fission.

Answer:
69.44kJ
Explanation:
Kinetic energy is expressed as;
KE = 1/2mv^2
m is the mass = 500kg
v is the velocity
Get the velocity;
v = displacement/time
velocity = 2000/120
velcoity = 16.7m/s
Gt the kinetic energy
KE = 1/2 * 500 * 16.7²
KE = 250*277.78
KE = 69,444.4Joules
Since 1000J = 1kJ
69,444.4Joules = 69,444.4/1000
69,444.4Joules = 69.44kJ
Hence the Secretariat's average kinetic energy is 69.44kJ
Answer:
Explanation:
Force on a current carrying conductor in a magnetic field is given by the following expression
F = B i L where B is magnetic field perpendicular to wire or current , i is current and L is length of the wire.
Magnetic field of 1.5 x 10⁻⁵ T is making an angle of 60 degree with the wire so the component of field perpendicular to it
B = 1.5 X 10⁻⁵ Cos 30° = 1.3 x 10⁻⁵ T.
Force = BiL
= 1.3 X 10⁻⁵ X .4 X 1
= 5.2 X 10⁻⁶ N.
The direction of force can be found out from Fleming's left hand rule . It will be along downward direction.
