Answer:
730.4 m
Explanation:
The sound waves travels with a uniform motion (=constant velocity), therefore we can calculate the distance it travels using the formula:
where
d is the distance
v is the speed of the sound wave
t is the time taken
In this problem we have:
v = 332 m/s is the speed of sound in air
t = 2.2 s is the time elapsed
Therefore, the distance between the tower and the person is
Answer: m∠P ≈ 46,42°
because using the law of sines in ΔPQR
=> sin 75°/ 4 = sin P/3
so ur friend is wrong due to confusion between edges
+) we have: sin 75°/4 = sin P/3
=> sin P = sin 75°/4 . 3 = (3√6 + 3√2)/16
=> m∠P ≈ 46,42°

Answer:
Explanation:
change in flux = no of turns x area of coil x change in magnetic field
= 163 x π 2.65² x 10⁻⁴ x ( .481 - 0 )
= 1728.84 x10⁻⁴ weber
rate of change of flux = change in flux / time
= 1728.84 x10⁻⁴ / .149
= 11603 x10⁻⁴ V .
volt induced = 1.16 V
current in the circuit
= volt induced / resistance
1.16 / 10.7 = .1084 A
energy dissipated = i²Rt where i is current , R is resistance and t is time.
= .1084² x 10.7 x .149
= .018734 J
= 18.73 mJ .
The correct answer is 24,000,000,000 km.
One AU(Astronomical Unit) is equal to 1.496 ×10⁸ kilometers.
∴ 160 AU = 160 × 1.496 ×10⁸ km
= 240 ×10⁸ Km = 24,000,000,000 km
