Due that the velocity is constant that means that friction force is equal to the force exert by you, otherwise the refrigerator will accelerate or decelerate and in both cases velocity will not be constant.
So then the friction force between refrigerator and floor is 150 Newtons.

Answer:
Dark matter does not affect our view, humans can see through them.
Explanation:
They do not affect our view because we can see right through the (weakly interacting) dark matter, as they do not interact or interfere with electromagnetic force.
Dark matter are often invisible substances and are difficult to spot because they don't absorb or reflect light.
Answer:
Explanation:
= Strain = 0.49
= 3.1 MPa
At t = Time = 32 s 
= 0.41 MPa
= Time-independent constant
Stress relation with time
at t = 32 s
The time independent constant is 16.0787 s
At t = 6
From the first equation
