Velocity can change when there is a change in direction and speed.
Answer:
the axes of the two polarizers are aligned, the angle between this axis must be zero
Explanation:
Polarizers are anisotropic systems where absorption is selective in each axis, in this case they indicate that on an axis they let 100% pass and perpendicular to this axis no light passes.
The first polarizer defines a direction of light that of its axis, it is said that the light is polarized, when this light reaches the second polarized, so that it can pass the axis must be in the direction of the polarized beam.
In summary, the axes of the two polarizers are aligned, the angle between this axis must be zero
Answer:
Explanation:
The initial velocity, u, of the car=15m/s
The final velocity, v, of the car =0m/s
Time, t, taken for the car to come to a stop=5s
Acceleration is calculated by,
By substitution,
The negative sign implies that the car has decelerated.
Answer:
The Answer is A. The slope is upward.
