Physics OBJ
1-10: DADACDBCCA
11-20: ADCCBCBDBC
21-30: AADCADCDCA
31-40: DACDBAADBC
41-50: BBDAACDDCA

(1a)
Q= 1/2 ev²
dimension for Q = M/L³ * L/T * L/T
=M/L * I/T²
=ML-¹T-²

(1b)
Mass flow rate

==================================

(2)
Given Range R = 7200
Using R max = u²/g
7200= u²/10
U²=72,000
U=√72000
U=268.3m|s
The missle should be lanuched at a spead of 268.3m|s

==================================

(3)
(i) Astronomical satellite
(ii) Weather satellite
(iii) communication satellite

===================================

(4)
(i)Origin up to point A
(ii)Origin up to B (the elastic limit)
(iii)The yield point is point C

==================================

(5a)
Optical fiber are often wrapped in handles so they may be used to carry light into, or image out of confined spaces.

(5b)
Total internal reflection

=================================

(9a)
(i)Humidity is the concentration of water vapour present in the air.
(ii) Saturated vapour can be defined as a state where the system is holding the maximum amount of water in vapour (gaseous form) at corresponding temperature and pressure.

(9bi)
Steam will produce more severe burns than boiling water because steam has more heat energy than water due to its latent heat of vaporisation.

(9bii)
Water pipes burst because the water inside them expands as it gets close to freezing, and this causes an increase in pressure inside the pipe . When the pressure gets too high for the pipe to contain, it ruptures.

(9biii)
(i)They travel linearly.
(ii)They have a negative electric charge.
(iii)They have particle property.
(iv)Magnets can deflect them.

(9c)
It receives electrical energy and converts it into two other forms: x-radiation and heat. The heat is an undesirable byproduct. X-ray tubes are designed and constructed to maximize x-ray production and to dissipate heat as rapidly as possible. The x-ray tube is a relatively simple electrical device typically containing two principle elements: a cathode and an anode. As the electrical current flows through the tube from cathode to anode, the electrons undergo an energy loss, which results in the generation of x-radiation.
