Why Bullets Spin When Shot From A Rifle Or Handgun?

The spiral grooves (called barrel rifling) inside the barrel of a rifle or handgun cause the bullet to spin. On pulling the trigger, the primer gets hammered and a spark is generated. This small explosion ignites the gun powder and a lot of gas and high pressure are produced. The bullet is forced out due to high pressure and passes through the barrel having helical grooves. These spiral grooves, also known as barrel rifling exert torque and forces bullet to spin.

Are flowers asexual or sexual?

Flowering plants can reproduce both by sexual and asexual means of reproduction. Sexual reproduction involves the fusion of male and female gametes which takes place through pollination by birds, insects, and water. This pollination causes the fertilization and the female ovules grow into seeds. Asexual reproduction can take place naturally as well as artificially. The natural vegetative propagation involves runners, tubers, plantlets, bulbs, corms, suckers, and keikis for asexual reproduction while there are several artificial methods such as cutting, grafting, and layering for asexual vegetative propagation. Many plants have the ability to propagate through both sexual and asexual reproduction.

We know that NH3 cannot produce hydroxide ions in gaseous state but it produces the same product as when the two substances were in solution. For example: NH3(aq) +
