ANSWERS
NUMBER 1
(1bi)
Firstly, the net force acting upon the object must be zero. Secondly, the net torque acting upon the object must also be zero.
(1bii.)
Let F1 = 4N and F2 = 3N.
Resultant force (R) = √(F1^2 + F2^2)
= √((4N)^2 + (3N)^2)
= √(16N^2 + 9N^2)
= √(25N^2)
= 5N(1bi)
(i)Firstly, the net force acting upon the object must be zero.
(ii)Secondly, the net torque acting upon the object must also be zero.

(2bi)
(i) The light ray moves from a more dense medium to a less dense medium.
(ii)The angle of incidence must be greater than the critical angle
(2bii)The Snell’s law of refraction states that: The incident ray, the refracted ray and the normal at the point of incidence, all lie in the same plane.
(2bi)
If the angle of incidence (θ₁) is greater than the critical angle (θ_c), then total internal reflection occurs.
(2bii) Snell’s law states that the ratio of the sine of the angle of incidence (θ₁) to the sine of the angle of refraction (θ₂) is equal to the ratio of the velocities of light in the two media, which is also equal to the inverse ratio of their refractive indices.
QUESTION 3
(a) The molar mass of the salt can be calculated using the formula:
Molar mass = Mass / Amount of substance
In this case, the amount of substance is given as 0.125 mol and the mass is given as 8 g. Substituting these values in the formula, we get:
Molar mass = 8 g / 0.125 mol
Molar mass = 64 g/mol
Therefore, the molar mass of the salt is 64 g/mol.
QUESTION 4
Two uses of artificial satellites are:
(i). Satellites are used for communication purposes to transmit radio, television, and telephone signals over long distances.
(ii). Satellites are also used for navigation purposes.
