Answer: 8.81 J
Explanation: The scalar or dot product of 2 vector equals the product of the magnitude of both vectors and the cosine value of the angle between them
Magnitude of vector f (force) as given in the question = 12.5N
Magnitude of length = 0.75m
Angle between vectors = 25°
F. Δr = 12.5 * 0.75 * cos 25
F. Δr = 12.5 * 0.75 * 0.9063
F. Δr = 8.81 J
Less force will be necessary to overcome inertia for the 80 kg piece of furniture.
Force is a factor that has the power to alter an object's motion. A massed object's velocity can be changed or accelerated by a force. A push or a pull is a straightforward method to explain forces.
The term "moment of inertia" refers to the quantity that describes how a body resists angular acceleration and is calculated by multiplying each particle's mass by its square of the distance from the rotational axis.
I = mr², where m is the mass of the object and r is the distance to the rotation axis.
Therefore, The inertia is directly proportional to the mass of the object.
So, as the mass increases the inertia increases.
Therefore, 80 kg piece of furniture will require less force to overcome inertia.

The appropriate response is a Surface wave. It is a seismic wave that goes over the surface of the Earth rather than through it. Surface waves as a rule have bigger amplitudes and longer wavelengths than body waves, and they travel more gradually than body waves do. Adore waves and Rayleigh waves are sorts of surface waves.
