A. The inner core heat produce stuff
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.

Answer:
Compression is that part of longitudinal wave in which the medium of particles are closer and there is momentary decrease in volume of medium.
Rarefaction is that part of longitudinal wave in which the medium of particles apart and there is momentary increase in volume of medium.
Compression is that part in which particles vibrating in a medium come closer to each other and rarefaction is that part in which particles vibrating in a medium move apart from each other .

Hey mate....
Explanation:
This is ur answer.....
<em>Another way to measure the strength of an earthquake is to use the Mercalli scale. Invented by Giuseppe Mercalli in 1902, this scale uses the observations of the people who experienced the earthquake to estimate its intensity.</em>
