100 Level Department Of X-Ray Technicians exam questions and detailed answers. Download the answers in document format. Correct, detailed, and straightforward answers.

Questions:

(a) Define the following:

[i] Measurement
[ii] Fundamental unit
[iii] Derived unit
[iv] Dimension

(b) Derive the first, second, and third equations of motion for a body traveling along a straight line with uniform acceleration. Use u, v, a, and t for initial velocity, final velocity, acceleration, and time of motion, respectively.

(c) Suppose an object traveled along a straight path with the velocity as shown in the table below for the first 20 seconds:

Velocity (m/s)	0.00	5.00	10.00	15.00	20.00	20.00	20.00	20.00	15.00	10.00	0.00
Time (s)	0.00	2.00	4.00	6.00	8.00	10.00	12.00	14.00	16.00	18.00	20.00

(i) Draw the velocity-time graph to illustrate the motion.

(ii) Calculate Acceleration, Retardation, and Total Distance traveled by the object.
