What do vertical and horizontal surface waves have in common?
- both waves travel along earth's surface and decrease in amplitude with depth below the surface.
- both waves travel within earth and increase in amplitude with depth below the surface.
- both waves travel along earth's surface and increase in amplitude with depth below the surface.
- both waves travel within earth and decrease in amplitude with depth below the surface.

Option A

Both waves travel along earths surface and decrease in amplitude with depth below the surface.

Explanation:

The vertical surface waves have a characteristic of traveling along the earth surface and as they go deeper below the earth's surface their amplitude decrease. Similarly, the horizontal surface waves also travel along the earth surface and experiences a decrease in amplitude as they travel deeper below the surface of the earth.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
