Answer:
T=1022.42 N
Explanation:
Given that
l = 32 cm ,μ = 1.5 g/cm
L =2 m ,V= 344 m/s
The pipe is closed so n= 3 ,for first over tone


f= 129 Hz
The tension in the string given as
T = f²(4l²) μ
Now by putting the values
T = f²(4l²) μ
T = 129² x (4 x 0.32²) x 1.5 x 10⁻³ x 100
T=1022.42 N
The answer is A because it describes both toy cars
Well,
One possibility is that there is much salt in the water, enough so that the sphere of steel floats.
Answer:
F = m × a = 50 kg × 0.8 m/s2 = 40 kg • m/s2, or 40 N
