It’s definitely D: seeing all the options available to you and giving one a try
Answer:
B. Neutral equilibrium
Explanation:
Equilibrium is defined as the point where the total net force on the system is zero and the net torque is zero as well.
Neutral equilibrium simply means when an object is displaced and obtains an entire new position.
Since the ice cube has been given a push, it slides down by changing it's position, this position changed makes its equilibrium neutral.
Answer:
Transverse wave
Explanation:
The wave is moving forwards from the hand to the point of attachment
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
