WAEC Physics Theory Answers
Original length Lo= 3m
Extension e = 310 = 3*3= 9m
F=ke where k = 982.3NM-²
The five that produce the extension F = 8.840.7N
Flat metal plates are mainly used to collect heat for space heating in solar panels for heat transfer.
They used a thermal insulator for the reduction of heat transfer between objects in thermal contact
The tube is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.
highly purified silica glass.
To confine the optical signal in the core the refractive index of the core must be greater than that of the cladding.
Escape velocity = VE
The radius of the earth = R
Acceleration because of gravity = 10ms²
Escape velocity Be=√2R
The angle at horizontal θ = 30°
Time of light, T = 25sec
The velocity of projection u =?
But T=2using sinθ/g
Torque is defined as a measure of the force that can cause an object to rotate about an axis
WAEC Physics Questions 2021 and Answers

Free fall simply means the act in which objects fall freely under the influence of gravitational force. An object in free fall does not encounter air resistance.
Height of tower H = 40.0m
Velocity v = 10.0m/s, time t=?, g=10.0m/s
Using the relation
S= ut + 1/2gt^2
H= ut + 1/2gt^2
40= 10t + 1/2*10t^2
4= t + t^2/2
= t^2 + 2t – 8=0 ( solving quadratically)
t+4=0 or t-2=0
t= -4 or t=2
Therefore, time to fall on the ground t=2s
R.d of oil =R1 = 0.72 R.d of water = R2=1.00 R.d of liquid= R1/R2= 0.72/1 = 0.72
R.d = density of wood(P1)/density of water(P2)
But the density of wood= mass of wood/volume of wood
0.72= mass of wood/8*8*8
Mass of wood = 0.72*512 = 368.64g
