Certain nuclear radiation that is passed through the electric field (above) is deflected towards the red plate.

in what way is the nucleus changed by this type of decay?
a) a proton is converted to a neutron.
b) a neutron is converted to a proton.
c) a positron is converted to an alpha particle.
d) there is no change to the nucleus because the mass remains remain the same.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

answer; equivalent to a one(1) horsepower motor;

i believe the answer is a hope it and is correct
