The two permanent magnets can interact with each other so that the two magnets are brought closer to the opposite poles so that they will attract each other

Further explanation

Magnets are objects that can attract other objects. Objects that are brought close to a magnet are attracted because they have a magnetic force

A magnetic field is a magnetic region that is still a magnetic force, so objects placed in a magnetic field will be attracted to a magnet

The strongest magnetic force is at the magnetic ends. This magnetic tip is called a magnetic pole consisting of the north pole and south pole

The magnetic north pole will point towards the north pole of the earth and the magnetic south pole will point towards the south pole of the earth.

Similar poles (north and south poles) will pull each other, while similar poles (north-north pole and south pole with the south) will repel each other

An iron or steel can be made into a magnet by rubbing, using an electric current or by induction.

Magnetic properties can be lost if magnets are heated or hit

Materials whose magnetic properties are easily lost are called temporary magnets such as iron and those that are hard to lose are called permanent magnets such as steel

The nature of materials that are exposed to or interact with magnets can give different responses. Some are drawn very strong, weak or even rejected. the nature of this material is classified into 3 namely ferromagnetic (easily drawn), paramagnetic (weakly drawn), and diamagnetic (slightly resisted)

So that the two permanent magnets can interact with each other, then the two magnets are brought closer to the opposite poles so that they will pull together

explanation:

the masses of the objects and the distance between them

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

$_a^z\textrm{x}\rightarrow _{a-2}^{z-4}+_2^4\alpha$

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

$_a^z\textrm{x}+_{-1}^0\textrm{e}\rightarrow _{z-1}^a\textrm{y}$

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases $\gamma -radiations$ . this process does not change the mass number.

$_a^z\textrm{x}^*\rightarrow _a^z\textrm{x}+_0^0\gamma$

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as $\beta ^+$ -decay. in this the mass number remains same.
