SECTION A (16marks)
Answer all questions in this section
1. Choose the most correct answer from the give alternatives given under each items and write its corresponding letter in the answer sheet provided.(16 marks)
(i)The best statement of frame of reference:
Sets of coordinate used to determine position and velocity.
Motion of object in air.
A set of lines used to show vectors.
Resolution of vectors.
Polar coordinate system.
(ii)The principle of fluid pressure which is used in hydraulic brake is the:
Pressure is the same at all levels in a fluid
Increase of pressure is transmitted equally to all parts of a fluid.
The pressure at a point in a fluid is due to the weight of the fluid above it.
Increase of pressure at a given depth is proportional to the depth in the fluid.
