WAEC Answers to Physics
Theory (1)
Original length = 3m Extension = 310 = 3*3 = 9m
F×e F=ke where k = 982.3NM-² F=982.3*9=8,840.7N
The five numbers that add up to F = 8.840.7N
(2a) Flat metal plates are most often used in solar panels to collect heat for space heating.
(2b) They used a thermal insulator to stop heat from moving between things that were in thermal contact.
(2c) The tube is a piece of equipment that controls the flow of electric current in a high vacuum between electrodes that have been given a difference in electric potential.

(3a) Very clean glass made of silica.
(3) For the optical signal to stay in the core, the core’s refractive index must be higher than that of the cladding.
(4) Escape speed equals VE
The earth’s size is given by R.
Acceleration due to gravity = 10 ms2 Escape speed Be=√2R
VE=√2*10R\sVE=√20R
(5) The angle at horizontal is 30°, and the time of light is 25 seconds.
The speed of the projectile, u, is?
But T=2using sinθ/g
25= 2u*sin30/10 25=0.5u/5
0.5u=125\sU=125/0.5 =250ms-¹
(6)\s(i)Coherence
(ii)Directionality
(iii)Monochromatic
(7ai) Torque is a unit of force that measures how much an object can turn around an axis.

(7aii)
Torque is determined by the following: the size of the force
– The length of the lever arm. – The angle between the force and the lever arm.
(7bi)
When something is in free fall, it just means that it falls freely because of the force of gravity. When something is falling freely, air doesn’t stop it.

(7bii)
Tower H is 40 meters tall.
Speed v = 10 m/s, time t =?, speed g = 10 m/s
With the formula S = ut + 1/2gt2
H= ut + 1/2gt^2 40= 10t + 1/2*10t^2 4= t + t^2/2
= t^2 + 2t – 8=0 (Using quadratic equations to solve) = (t+4)(t-2)=0
t+4=0 or t-2=0
t= -4 or t=2
So, the time to fall down is t = 2s.
R.d. of oil = R1 = 0.72 R.d. of water = R2 = 1.00 R.d. of a liquid = R1/R2 = 0.72/1 = 0.72
R.d. = wood density (P1)/water density (P2) = 0.72 = P1/1.00
P1= 0.72*1.00=0.72g/cm³
But the density of wood is the weight of wood divided by its volume.
0.72 = weight of wood (8*8*8)
The weight of the wood is 0.72*512 = 368.64g
