Answer:

Go to the excited aluminum-28 isotope

Explanation:

In the processes of nuclear reactions, fundamental changes occur at the level of the atomic nucleus.

Analyze the characteristics of the neutron that has approximately the mass of the proton and has no electric charge, so when being absorbed by the aluminum core the atomic number should not be changed, but the atomic mass should increase by one unit.

The new atom formed is in an excited state and enters the base state with the emission of a high-energy radiation, gamma ray that does not transform the atom

Tthe reaction is:

⁷A₂₇ + ⁰n₁ → ⁷Al₂₈ˣ

The symbol "ˣ" means excited

⁷Al₂₈ˣ → ⁷Al₂₈ + γ

A bulb converts 9J of energy in each second from an input of 100J of energy. Calculate efficiency of this light bulb

77julia77 [94]

Efficiency is calculated through dividing the actual mechanical advantage by the hypothetical mechanical advantage:

- the actual mechanical advantage is 9J because that's how much work the light bulb doing

- the hypo. mechanical advantage is 100J. Ideally, in a perfect world, the light bulb can convert 100J input into 100J output, but do to resistance and other factors it is not possible.

$\frac{9}{100} = .09$
change the decimal to a percentage:

$.09 = 9\%$
the light bulb had 9% efficiency

You have two lightweight metal spheres, each hanging from an insulating nylon thread. One of the spheres has a net negative char

kkurt [141]

Answer:attract each other

Explanation:

When two-sphere, one with a negative charge and another neutral is brought close together but do not touch then they try to attract each other.

This because of the polarization of the neutral sphere as it is placed in the vicinity of a negatively charged sphere. The negatively charged sphere will induce the positive charge in the neutral sphere and they will attract each other according to Columb law.
