In what order do seismic waves arrive at a seismograph station?

P waves, S waves, L waves and Rayleigh Waves.

Explanation:

The 4 types of seismic waves which are S-waves, P-waves, L-waves and Rayleigh Waves arrive at a seismograph station in this order:

The first waves that arrive are the P-waves which are the fastest waves of all 4 of them. The second waves that arrive at the station are S-waves followed by L waves and Rayleigh waves.

I hope this answer helps.

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true
