### The speed of light is...

• A.

300 m/s

• B.

300 km/h

• C.

None of above

C. None of above
Explanation
The speed of light is not 300 m/s or 300 km/h. The correct answer is none of the above because the speed of light in a vacuum is approximately 299,792,458 meters per second (m/s). It is a fundamental constant in physics and is the maximum speed at which information or energy can travel in the universe.

### An object is at point V (2,3,4) then moves to Z ( 5,0,1) then determine it's displacement vector....

• A.

3i + 3j -3k

• B.

3i - 3j - 3k

• C.

2i + 4k

• D.

I don't know

B. 3i - 3j - 3k
Explanation
The displacement vector is determined by subtracting the initial position vector from the final position vector. In this case, the initial position vector is (2, 3, 4) and the final position vector is (5, 0, 1). Subtracting the initial position vector from the final position vector gives the displacement vector of (5-2, 0-3, 1-4), which simplifies to (3, -3, -3).

### U throw a ball upward, the velocity of ball when it's on max high is...

• A.

Max velocity

• B.

0 m/s

• C.

Same as initial velocity

B. 0 m/s
Explanation
When you throw a ball upward, it will eventually reach its maximum height before falling back down. At this point, the velocity of the ball is 0 m/s because it has momentarily stopped moving in the upward direction and is about to start moving downward. Therefore, the correct answer is 0 m/s.
