How long does it take a P-wave to travel 7,000 km? minutes b) How long does it take an S-wave to travel 7,000 km? minutes c) How long does it take a Love wave to travel 7,000 km? minutes d) How long does it take a Rayleigh wave to travel 7,000 km? minutes

A. 8.64 secs.

B. 14.58 secs.

C. 26.002 secs.

D. 33.46secs.

Explanation:

A. P wave would travel 7000km

p-wave travels on a speed of 13.5km/s

= 7000km/13.5km/s

= 8.64 secs.

B. S-wave time to travel 7000km

s-wave travels on a speed of 8km/s

= 7000km/8km/s

= 14.58 secs.

C Love wave travels at a speed of 10,000m/s ( 2.7778 m/s ).

= 7000km to miles

= 4349.598m/2.788m/s

= 26.002 secs.

D. Rayleigh wave to travel 7,000 km

10,000m/s ( 2.1667 m/s ).

= 7000km to miles

= 4349.598m/2.1667m/s

= 33.46secs.

a sonic boom is a loud boom that breaks the sound barrier

explanation:

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
