When the angle of the ramp increases, the weight of the box acting perpendicular to the ramp decreases.
<h3>
Normal reaction of the box</h3>
The normal reaction of the box is due to weight of the box acting perpendicular to the ramp.
Fn = Wcosθ
<h3>when the angle of the ramp = 30⁰</h3>
Fn = Wcos(30)
Fn = 0.866W
<h3>when the angle of the ramp = 45⁰</h3>
Fn = W x cos(45)
Fn = 0.7071W
Thus, when the angle of the ramp increases, the weight of the box acting perpendicular to the ramp decreases.

Longer I took a little physics but I remember them saying that a small star lasts longer than a larger star
Answer:
Direction
Explanation:
A vector is a geometrical representation of physical quantity. It has a particular direction with a specific magnitude.
In the geometry of space whether it is two dimensional or three dimensional the vector quantity has a specific direction. Such as a stone is thrown with a velocity in a particular direction.
The path of the stone in three-dimension shows its direction and speed is its magnitude.
Hence, the velocity of stone has two property magnitude mentioned as speed and particular direction.
On writing the mathematical expressions for vectors, it is denoted by arrow mark on its top as shown below.
Power = work / time --> time = work / power = 3600 J / 275 watts = 13.1 seconds.
