The correct answer to the question is: Sound wave.
EXPLANATION:
Before going to answer this question, first we have to understand longitudinal wave.
A longitudinal wave is a mechanical wave in which the direction of propagation of wave is parallel to the direction of particle vibration.
This wave propagates through a medium in the form of compression and rarefaction.
Compression are the regions of high pressure zones where the particles of the medium are closely aggregated to each other.
Rarefaction is the region of low pressure where particles of the medium are not so close to each other as compared to compression.
The longitudinal wave can not propagate in space. It always needs a medium for it's propagation. The medium may be solid, liquid or gas .
For instance, sound wave is a longitudinal wave.
Hence, the correct answer of this question is sound wave which needs a medium for it's propagation.

Answer:
(A). The rotational momentum of the flywheel is 12.96 kg m²/s.
(B). The rotational speed of sphere is 400 rad/s.
Explanation:
Given that,
Mass of disk = 10 kg
Radius = 9.0 cm
Rotational speed = 320 m/s
(A). We need to calculate the rotational momentum of the flywheel.
Using formula of momentum
Put the value into the formula
(B). Rotation momentum of sphere is same rotational momentum of the flywheel
We need to calculate the magnitude of the rotational speed of sphere
Using formula of rotational momentum
Put the value into the formula
Hence, (A). The rotational momentum of the flywheel is 12.96 kg m²/s.
(B). The rotational speed of sphere is 400 rad/s.
Answer:
10N/m
Explanation:
Using F=kx
F=mg
k=mg/x
k=0.1*10/0.1 (kg*m/s^2)/m
10N/m
