Answer:
A wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
<span>Displacement of the oscillator can be expressed in the mathematical form as:
x(t) = A*cos (ωt + δ),
therefore acceleration would be represented as => a = ¨x = â’ω^2*A*cos (ωt + δ),
the maximum acceleration will happen when the cosine is -1.
Hence, maximum acceleration => a-max = A*ω^2
The force associated with acceleration is F = ma.
Therefore maximum amplitude is
A = F / (m*ω^2)
= F / (4Ď€^2 * m * f^2) where f is the frequency of oscillation.
putting values in above equation we ge:
A = 50000 / 4Ď€^2 * 10^â’4 Ă— (10^6)^2
= 1.25 * 10^â’5
hence 1.25 * 10^-5 m/s^2</span>
Answer:
Explanation:
We are given that
Mass of one asteroid 1,
Mass of asteroid 2,
Initial distance between their centers,d=13.63 R
Radius of each asteroid=R
d'=R+R=2R
Initial velocity of both asteroids
We have to find the speed of second asteroid just before they collide.
According to law of conservation of momentum
According to law of conservation of energy
Hence, the speed of second asteroid =
Answer:
Energy is an essential part of life because all of human activities require energy.
Gamma rays<span> are produced in the disintegration of radioactive atomic nuclei and in the decay of certain subatomic particles. ... When an unstable atomic nucleus decays into a more stable nucleus (see radioactivity), the “daughter” nucleus is sometimes produced in an excited state.</span>
