Background Information Terminal velocity is when a falling object reaches a constant velocity due to a balance in the forces of weight and air resistance. In this experiment‚ we dropped marbles of difference weights in 100 ml of oil to calculate their terminal velocity. Research Question How does the mass of an object effect its terminal velocity? Aim Our aim is to measure the terminal velocity‚ of marbles of different masses‚ in oil. hypothesis Objects of larger mass will take longer to reach

What are the main parts of a neuron? Please define axon‚ dendrites‚ soma‚ terminal buttons and synapse. The main parts of a neuron are: Axon‚ Dendrites‚ terminal buttons and myelin sheath. Axon: The axon receives and carries messages by the dendrites in other neurons. It is the longer part of the rest of the neuron and it is covered with a protective coat of fat called myelin sheath. The axon finish with the terminal buttons. Dendrites: the dendrites receive messages from other neurons. Soma:

Normalization A logical design method which minimizes data redundancy and reduces design flaws. Consists of applying various “normal” forms to the database design. The normal forms break down large tables into smaller subsets. First Normal Form (1NF) Each attribute must be atomic • No repeating columns within a row. • No multi-valued columns. 1NF simplifies attributes • Queries become easier.
