Hence, the correct answer is option A,B and C
Answer:
The mass of the object is 15.0 kg
The weight of the object is 147.15 N
Explanation:
The mass of the object is the quantity of matter contained in the object or the measure of the its property of inertia.
The mass is constant through out the universe
The mass of the object is given as 15.0 kg
The weight of the object is the force of attraction of the Earth on the object
The weight is dependent on the interacting objects.
The weight of the object = The mass of the object × Acceleration due to gravity
Where;
The acceleration due to gravity, g = 9.81 m/s²
∴ The weight of the object = 15.0 kg × 9.81 m/s²= 147.15 N
The weight of the object = 147.15 N
