The three types of seismic waves are p waves, s waves and t waves. select the best answer from the choices provided t f

FALSE

Explanation:

There exist only two types of seismic waves

1) P waves

2) S waves

P waves are compression waves which is produced due to pushing and pulling. These waves can travel trough any medium i.e. Solid, Liquid or Gas and also these waves travels at high speed.

S Waves are secondary waves which travels at slow speed comparative to P waves. These waves can only travel through solid rocks and travels at slower speed with respect to P waves

So given statement is not true.

ill do it for 100, also this isnt 80 its 40

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
