Increasing
Explanation:
If a ship is moving forward and has a positive acceleration, we can say that the velocity of the ship is increasing.
Velocity is the rate of change of displacement of a body with time.
Acceleration is the rate of change of velocity with time.
Acceleration =
If a ship is moving with positive acceleration, the velocity of the ship is increasing also.
- This is because when velocity is increasing, the change will be positive.
- From the equation, to have positive velocity, the final velocity must be greater than the initial one.
- With this, acceleration will be positive.
- So we can say, velocity of the ship is increasing.

Answer:
An atom is the smallest unit of matter that retains all of the chemical properties of an element. Atoms combine to form molecules, which then interact to form solids, gases, or liquids. For example, water is composed of hydrogen and oxygen atoms that have combined to form water molecules. Many biological processes are devoted to breaking down molecules into their component atoms so they can be reassembled into a more useful molecule.
Atomic Particles
Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged). Atoms have different properties based on the arrangement and number of their basic particles.
The hydrogen atom (H) contains only one proton, one electron, and no neutrons. This can be determined using the atomic number and the mass number of the element (see the concept on atomic numbers and mass numbers).
