Which type of radioactive particle was emitted by the following isotopes?

Radioactive decay or disintegration is a process through which unstable nuclei form q more stable nuclei by the release of elementary particles like alpha particles, beta, protons, neutrons etc along with the release of energy.

In the given examples:

a) N-13 will get converted in to carbon, C-12 along with the release of a proton as shown below:

₇N¹³ →  ₆C¹²  +  ₁H¹

b) N-15 will get converted in to boron B-11 along with the release of an alpha particle

₇N¹⁵  →  ₅B¹¹  +  ₂He⁴

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
