Answer:
The weight of this object is 8.45 N.
Explanation:
Given;
volume of the object, V = 7.5 x 10⁻⁴ m³
density of the object, ρ = 1.15 x 10³ kg/m³
The mass of the object is given as;
mass = density x volume
m = ρV
m = (1.15 x 10³)(7.5 x 10⁻⁴ )
m = 0.8625 kg
The weight of the object is given as;
w = mg
where;
g is acceleration due to gravity = 9.8 m/s²
w = 0.8625 x 9.8
w = 8.45 N
Therefore, the weight of this object is 8.45 N.
