Answer:
As the particles move further away from their normal position (up towards the wave crest or down towards the trough), they slow down.
Explanation:
This means that some of their kinetic energy has been converted into potential energy – the energy of particles in a wave oscillates between kinetic and potential energy. Hope that this helps you and have a great day :)
Answer:
Explanation:
For first overtone
Standing waves will be formed lengthwise and breadth-wise in the enclosures having dimension of .75m x 1.5 m
A ) For the formation of lowest two frequencies formed by standing waves along the breadth , fundamental note and first overtone may be considered.
For fundamental note ,
the condition is
wave length λ = 2L = 2 x 0.75 m
λ = 1.5 m
frequency n = v / λ
= 343 / 1.5
= 229 Hz approx
For first overtone
λ = L = 0.75m
frequency n = v / λ
n = 343 / 0.75
= 457 Hz approx
B)
For the formation of lowest two frequencies formed by standing waves along the length , fundamental note and first overtone may be considered.
For fundamental note ,
the condition is
wave length λ = 2L = 2 x 1.5 m
λ = 3 m
frequency n = v / λ
= 343 / 3
= 114 Hz approx
frequency n = v / λ
n = 343 / 1.5
= 229 Hz approx
Answer:
the answer is at
Explanation:
Dimension of at = [ LT^-2 ] [ T ]
= [ LT^(-2+1) ]
= [ LT^-1 ]
which is same as dimension of speed.
Time = 13.5 / 2.5 = 5.4 seconds
Explanation:
Webb gives us new and unique eyes of places that we have never been able to reach.” With NASA and the European Space Agency's Hubble pushing 32 years in orbit, the bigger, 100 times more powerful Webb is widely viewed as its successor even though the two are vastly different.
