An unpolarized light wave is traveling along positive X-axis. The electric field vector in the beam vibrates in the direction of
A. Positive Y-axis definitely
B. Negative X-axis
C. Positive X-axis
D. Y or Z-axis
​

The answer is a i think

We can infer that star y is closer but other factors must be considered include the heat of the star, the mass, and the brightness of the star. even though star x seems dimmer it may just be less bright or contains less heat.

Gravity, from the center of mass of the box, extending downward normal force, from the floor under the box, extending upward, equal to gravity push force, acting at a point on the box, extending in the direction of motion friction, acting at any point on the box directly opposite the push, extending directly opposite to the motion

All u need to do is see how 50cm work with each other
