The distribution of light when passed through a prism or 1. other device that breaks the light into its Individual components. 2. where the electrons are found. The broad bands or regions located around the nucleus 3. Energy available or given off in specific, predictable quantities square energy level square emission spectrum square quantum
- An atom is most stable when it has eight electrons in its outermost energy level. This is a statement of the square rule.
- PHYS III (B) (i) Physics can be defined as the study of the interaction between matter and energy. It is an empirical science which means it is based on measurement . What are the basic fundamental measurable quantities in physics called?Also, state the quantities that are encountered mechames D. market (ii) These fundaments measurable quantities have an important application namely verifying physical laws expressed as equations State the principle tipon which this application is hased (2) marks) (iii) Using this principle . explain if the following equation is correct. d=v/1, where it's distance, wa velocity and 1= time (4 marks) __ (b) (i) In physics one way of classifying physical quantities is to classify them as either scalars or vectors Explain how a vector differs from a scalar and give an example of one. (ii) A.coin on a flat table is first of all moved 2cm from jeft to right in a straight line then moved 3cm in a straight Time at an angle of 60^circ above its original direction (2 marks) (2 marks) Determine the displacement of the coin from its original position in terms of unit vectors (2)/(4) and hat (i) where hat (i) is the unit vector in the positive x direction from left to right and the unit vector in the positive y direction from bottom to tope 2. How far away from the original position is the com? (2 marks) (ii) Xia in classical Newtonian mechanics.kinematics can be drined as thestudy of motion without taking amo account the forces causing the motion State the finear kinematic equations.(3 marks) (ii) Rotich throws a stone at a bird which is directly above his head Unfortunately he misses as the stone stops just before it hits the bird A. At the bird was som directly above Rotich calculate the speed with which the stone left his hand (2 marks) 2. For what length of time did the stone cravel before stopping? (2 marks) Transforming Lives Through Quality Education
