Primary (P) waves<span>a type of seismic wave that involves alternating compression and expansion of the material through which it passes.
6 to 13 kilometers per second, these waves arrive before S waves. 1.7 times faster than S waves. These waves are compressional.</span>Secondary (S) waves<span>a seismic wave that involves oscillation perpendicular to the direction of propogation.
second to arrive and bigger amplitude than P waves. These waves are shear.</span>
Answer:
400J
Explanation:
K. E = 1/2mv^2
If the speed is doubled, then it becomes :
K. E(2)= 1/2(m2v)^2
K. E(2) = 1/2m4v^2
K. E(2)=m2v^2
K. E(2)/K. E = (1/2mv^2)/(m2v^2)
K. E(2)/K. E =1/4
Therefore, K. E(2) = 4K.E
When k. E=100j
K. E(2)=4 *100 =400J
A)
If it were a warmer temperature, the air molecules would be moving faster. If particles are moving faster, they can transmit sound faster.
