Answer:
115kg
Explanation:
Given parameters:
Weight of the refrigerator = 1127N
Unknown:
Mass of the refrigerator = ?
Solution:
Weight is the force that acts on an object due to gravity;
Weight = mass x acceleration due to gravity
Acceleration due to gravity = 9.8m/s²
Now, input the parameters and solve for mass;
1127 = mass x 9.8
mass = = 115kg
Force can be exerted into an object with out it moving, but if you were to move the object due to force it would be considered work. (yes, you can exert force without having the object moving)
Volume=0.09m³
Density=4000kg/m³
Force=?
Density=mass/volume ⇒mass=volume×density
m=0.09×4000=360kg
Force=mass×accelaration
F=360×9.8
F=3528N
