Which vector should be negative? any vector whose magnitude is less than 1 a displacement in the direction north any vector whose magnitude is greater than 1 the velocity of a falling object

the velocity of a falling object.

As the object is falling down it is experiencing a velocity that is continuously reducing each second and becomes 0 once it reaches the ground. The graph between velocity and time in this case would be a negative slope.

Thus for a object falling down the velocity considered would be negative owing to the reducing speed.

wavelength divides in half and speed stays the same.

just took the test its not "d"
