(1a)
Young modulus of a material or the modulus of elasticity. 

(1b)
Potential Energy to kinetic Energy.

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


(2)
e = 0.7m
m=60 × 10^-3kg = 6.0×10^-2kg
K = 200Nm^-1
W = 1/2ke² = 1/2mv²
1/2ke² = 1/2mv²
V² = ke²/m = 200×0.7²/6.0×10^-2
V² = 98×10²/6
V² = 16.33×10²
V = √1633
V = 40.4
Speed = 40.4ms^-1

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


(3)
(i) Optical fibres have extremely high bandwidth
(ii) They have longer transmission distance
(iii) They have resistance to electromagnetic interference


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

(4a)
It is used in geometric stations used to move a satellite from low earth orbit into a geostationary orbit. 

(4b) 
Polar orbit satellite is used in earth mapping.

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

(5a)
(i) Centripetal force
(ii) Centrifugal force

(5b)
Ft = mDv
where  F = force
       t = time
       Dv = change in velocity
       m = mass of object

Hence F = mDv/t
