Answer:
Length (L2) = 0.51m
Wavelength of string (∆) = 1.02m
Wavelength of sound produced = 0.7795m
Explanation:
Using the equation L1F1 = L2F2
L1 = 0.68m, F1 = 330Hz, F2 = 440Hz
Therefore, (0.68m)(330Hz) = (L2)(440Hz)
L2 = 0.68m × 330hz/440hz
L2 = 0.51m
0.68m - 0.51m = 0.17m from the but
B. ∆ = 2×length (L2)
∆ = 2(0.51) = 1.02m
C. Frequency (f) = 440Hz
V = ∆f
343m/s =∆×440hz
∆ = 343m/s/440hz
∆ = 0.7795m
Answer:
0.0044 J
Explanation:
The kinetic energy of an object is given by:
where
m is the mass of the object
v is the speed
For the ball in this problem,
m = 50.0 g = 0.050 kg
v = 42 cm/s = 0.42 m/s
Therefore, the kinetic energy is
