It's due to Inertia. The law of Inertia states that a body will try to retain its movement state if possible. This means, if a body is at rest, it will try to remain at rest using forces. Similarly, if it's in movement, it will try to remain in movement.
In this example, the plane is moving forwards, and so do the seats, which in turn push the passenger forwards.The force felt is Inertia acting on the body, trying to counter the movement.
Slow moving vehicles that travel at a sped less than 25 MPH will have ...........
Slow moving vechicles [SMV] are those vehicles that travel on the road at a speed that is less than the recommended speed, example of a slow moving vehicle is tractor. These vehicles must have SMV signs on them to notify other drivers that they would not be travel fast.
1/f= 1/di+1/do
1/f=1/90m+1/40m
1/f ≈27.7m
Answer:
540 nm
Explanation:
According to the question,
The refractive index of the soap bubble, 
.
The thickness of the soap bubble wall is, 
.
Now, for constructive interference of soap bubble.
.
Now for first order m=1.
Therfore,
Substitute all the variables in the above equation.
.
Therefore,
.
Therefore the visible light wavelength which is strongly reflected is 540 nm.
