1. a seismograph station is located 2000 km from an earthquake’s epicenter. explain the order that the s and p waves will arrive at the station. using what you know about the characteristics of the different waves, explain your answer.

answer; equivalent to a one(1) horsepower motor;

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !
