prisoha [69]

Answer:

B ) 1.5 m/s

Explanation:

For the apparent frequency reflected by enemy submarine , the Doppler effect formula is

F = F₀ ( V + v) / (V - v)

F anf F₀ are real and apparent frequency , V and v are velocity of sound and velocity of enemy submarine respectively.

ΔF / F₀ = $\frac{2\times v}{V -v}$

Put ΔF = 200; F₀ = 100000 and V = 1482

200 / 100000 = $\frac{2\times v }{1482-v}$

v = 1.5 m s⁻¹ .

murzikaleks [220]

Answer:

Lifetime = 4.928 x 10^-32 s

Explanation:

(1 / v2 – 1 / c2) x2 = T2

T2 = (1/ 297900000 – 1 / 90000000000000000) 0.0000013225

T2 = (3.357 x 10^-9 x 1.11 x 10^-17) 1.3225 x 10^-6

T2 = (3.726 x 10^-26) 1.3225 x 10^-6 = 4.928 x 10^-32 s
