NigeriaSat-1 is a micro satellite used in monitoring disasters managements and various mapping campaign WHILE NigercomSat-1 is a mega satellite responsible for creating an enabling environment for competition among operators in the industry as well as ensuring the provision of qualitative and efficient telecommunications services

(1c)
V = image
U = Object
V = 2u
1/f₀ = (1/V) + (1/u)
1/f₀ = (1/2u) + (1/u)
1/f₀ = (1+2)/2u
1/f₀ = 3/2u
f₀ = 2u/3
Magnification = (V/f₀ + 1)
M = [2u/(2u/3)] + 1
M = [(2u/1) x (3/2u)] + 1
M = 3 + 1
M = 4

SCALAR QUANTITIES
(i) They have magnitude but no direction.
(ii) Scalars are added by ordinary algebraic methods.

VECTOR QUANTITIES
(i) They have both magnitude and Direction.

R=5N
***************************************

(3i)
The floatation principle states that when an object floats in a liquid, the buoyant force acting on the object is equal to the object’s weight.

(3ii)
{PICK ANY TWO}
(i) The density of the fluid.
(ii) The volume of the fluid displaced.
(iii) The local acceleration due to gravity.
***************************************

(5a)
{PICK ANY DEFINITION}
(i) Positive charge: This type of charge can be produced by rubbing a glass rod with silk.

OR

(ii) Negative charge: It can be obtained on an ebonite rod by rubbing it with fur.

(5b)
V1= 500cm³
T1 = 23° + 273= 296k
P1 = 600mmHg
V2 = ?
T2= 37° + 273 = 310K
P2 = 720mmHg

V1P1 / T1 = V2P2 / T2
500 x 600 / 296 = V2 x 720 / 310
V2 = 500 x 600 x 310 / 720 x 296
V2 = 436.37 cm³
***************************************
(6a)

(6b)
(i) Water waves
(ii) Sound waves

(ii) It causes wear and tear of machines.
(iii) It decreases the life expectancy of moving parts of vehicles.

(12bi)
The bob does not oscillate forever. It comes to rest because air resistance resists its motion. The pendulum loses its kinetic energy to overcome this friction and stops after some time.

(12bii)
The period of oscillation of a simple pendulum is known to be affected by the length of the pendulum and the acceleration due to gravity. The period is known to be completely independent of other factors like the mass of the pendulum.
