<span>A body wave is a seismic wave that moves through the interior of the earth, as opposed to surface waves that travel near the earth's surface.
P and S waves are body waves. Each type of wave shakes the ground in different ways</span>
Momentum = (mass) x (speed)
= (0.4 kg) x (45 m/s)
= 18 kg-m/s in the direction from the mound to the plate.
Answer:
b) the reflected pulse returns inverted while the transmitted pulse is right side up
Explanation:
A wave pulse traveling to the right along a thin cord reaches a discontinuity where the rope becomes thicker and heavier.
Then, as far as orientation of reflected and transmitted pulses are concerned the reflected pulse returns inverted while the transmitted pulse is right side up.
Hence the correct answer is b.
I think that chalk is a compound. it is made up of molecules containing one calcium atom ,one carbon atom and three oxygen atoms.
Answer:
Explanation:
given,
scattering angle of alpha particle = 25.0° above its initial direction of motion
oxygen nucleus recoils at = 50.0° below this initial direction.
final speed of the oxygen = 2.08×10⁵ m/s
mass of alpha particle = 4.0 u
mass o oxygen nucleus = 16 u
momentum conservation along x- axis
....(1)
Along y-direction
putting value in equation (1)
