Answer:
The correct solution is option A "10 meters".
Explanation:
The given values are:
Wave X,
Frequency,
Wavelength
Wave Y,
Let its wavelength =
As we know,
⇒
For both waves, medium is same then
then,
On substituting the estimated values in the above equation, we get

Answer: it should be Boyle’s law
initial velocity, u = 0
final velocity, v = 80 ft/s
acceleration, a = 150 ft/s²
Let the time taken is t.
v = u + at
80 = 0 + 150 x t
t = 0.53 second
