Answer:
-0.4454 Joules
Explanation:
m = Mass of block = 2 kg
h = Height of extension = 17 cm = x
g = Acceleration due to gravity = 9.81 m/s²
Potential energy of the spring
The kinetic energy of the spring
In this system as the potential and kinetic energy is conserved from work energy equivalence we get
The work done by friction is -0.4454 Joules
The ideal mechanical advantage of the pulley system is 3
The answer is; pressure
The sound is a longitudinal wave meaning the particles vibrate parallel to the direction of the wave. Sound waves, therefore, produce compression (akin to the crest in a transverse wave) and rarefaction regions (akin to a trough in a transverse wave) as its energy is propagated in the medium.
Answer:
Explanation:
As we know that the displacement of the particle from the mean position is 1/5 times of its amplitude
so we have
so now we have
now we have
so the phase other particle in opposite direction is given as
so we have phase difference given as
