An inclined plane which makes an angle of 30o with the horizontal has a velocity ratio of
Answer Details
The velocity ratio of an inclined plane is the ratio of the distance an object is moved along the plane to the vertical distance it is lifted. It is also equal to the inverse of the sine of the angle of inclination of the plane.
In this case, the angle of inclination of the plane is 30 degrees. Therefore, the sine of the angle is 0.5 (sin 30 = 0.5). The velocity ratio is the inverse of the sine, which is 2 (1/sin 30 = 2).
Therefore, the answer is 2.
