Nuclear chain reactions within power plants do NOT produce bomb-like explosions primarily because the ________.
Gelneren [198K]

Answer: D. Density of uranium within nuclear fuel rods is insufficient to become explosive

Explanation: Nuclear power plants use the same fuel as nuclear bombs, i.e. radioactive Uranium-235 isotope. However, in a nuclear power plant, the energy is released more slowly unlike in a nuclear bomb. <em>The energy released is through nuclear fission, and radioactive decay occurs at the same rate as in nuclear bombs. therefore, option A, B</em><em> </em><em>and C are incorrect.</em>

The primary reason why nuclear chain reactions within power plants do NOT produce bomb-like explosions is because the uranium fuel rods used in electricity generation is not sufficiently enriched in Uranium-235 to produce a nuclear detonation. This is the same idea in option D which is the correct option.

Consider a wire of length L = 0.30m that runs north-south on a horizontal surface. There is a current of I = 0.50A flowing north
ankoles [38]

Answer:

Part a)

F = 4.6 \times 10^{-6} N

Part b)

F = 8.2 \times 10^{-2} N

Explanation:

Part a)

As we know that the magnetic force on the current carrying wire is given as

F = i(\vec L \times \vec B)

so we have

F = iLB sin\theta

F = (0.50)(0.30)(0.5 \times 10^{-4}) sin38

so we have

F = 4.6 \times 10^{-6} N

Part b)

Now magnetic field is changed to 0.55 T

so we will have

F = (0.50)(0.30)(0.55) sin90

F = 8.2 \times 10^{-2} N
