The modern model is in 3D waves unlike the Bohr which is in circularize patterns.
Answer:B
Explanation:
Calculate speed using equation:V=S/t
S=980 km ------------ distance Boston-Detroit
t=2h --------------------- time
v=?
------------------------
V=S/t
V=980km/2h
V=490km/h
Explanation:
Initial speed of blood, u = 0
Final speed of the blood, v = 26 cm/s
(a) Displacement of the blood, d = 2 cm
Let a be its acceleration. It can be calculated using third equation of motion as :
(b) Let t is the time taken by the blood to reach its final speed. It can be calculated as :
<u></u>
t = 0.15 s
Hence, this is the required solution.
I am pretty sure that the only statement which is true for particles of the medium of an earthquake P-wave is being shown in the option : b)vibrate parallel to the wave, forming compressions and rarefactions. As you know, <span> it can be formed in two ways : from alternating </span>compressions<span> and </span>rarefactions<span> or </span><span>primary wave. I bet you will agree with me.</span>
