Answer:
19.33°C
Explanation:
To find the value of T you use the following formula:
v: speed of sound
To calculate v you use:
λ: wavelength = 0.651m
f: = 545Hz
by replacing :
Finally, by replacing in the first formula you obtain:
T = 19.33°C

Answer:
The angular speed of the wheel is 0.452 rad/s
Explanation:
The angle through which the car wheel turns, Δθ = 277° = 277/360 × 2·π radian
The time it takes for the car wheel to turn, Δt = 10.7 s
The angular speed, ω is given by the following equation;
Substituting the known values for Δθ and Δt gives;
The angular speed of the wheel = 0.452 rad/s
