Answer:
Explanation:
Wave produced in string and waves produced in air are different . The only similarity is that their frequency are equal . Otherwise , no similarity . One is transverse ( on wire ) , the other is longitudinal ( air ) . Their velocities too are different .
velocity = wavelength x frequency
if frequency is constant
wavelength ∝ velocity
wavelength is proportional to velocity . Since their velocities are different , their wavelength too will be different.
You should write meter per second square for the acceleration in words
Centripetal Force, F = mv²/r
Where m = mass in kg, v = velocity in m/s and r = radius of curvature in m.
Centripetal Force, F = 2000 * 25² / 80. Use your calculator.
F = 15 625 N.
a. cool air warms as it mixes with denser air
Explanation:
c. warm air is displaced by cooler denser air
