Answer:
2 * 10^4
Explanation:
(3 * 10^4)(4 * 10^4) / (6 * 10^4)
= (12 * 10^8)/(6 * 10^4)
= 2 * 10^4
Answer:
a), b), d), and e) are correct.
Explanation:
c) is incorrect because an object that has a definite shape cannot be in a gaseous state as gaseous objects take the shape of their container.
a) is correct because objects that are liquid have definite volumes but no definite shapes as they take the shape of their containers,
b) is correct as this is the definition of an object which is in a solid state.
d) is correct as this is the definition of an object which is in a gaseous state.
e) is correct as rigidness, the quality of having a definite shape is only exhibited by objects that are in solid state.

Physical indicates connected with, pertaining to, the animal or human body as a material organism: physical strength, exercise. Bodily means belonging to, concerned with, the human body as distinct from the mind or spirit: bodily pain or suffering.
Answer:
Wavelength, 
Explanation:
Given that,
Number of cycles in a spiral spring is 2.91 in every 3.67 s
The velocity of the pulse in the spring is 0.925 cm/s, v = 0.00925 m/s
To find,
Wavelength
Solution,
Number of cycles per unit time is called frequency of a wave. The frequency of the longitudinal pulse is,

The wavelength of a wave is given by :



So, the wavelength of the longitudinal pulse is 0.011 meters. Hence, this is the required solution.
