Answer:
0.15 s
Explanation:
From the question given above, the following data were obtained:
Speed of sound (v) = 330 m/s
Distance (x) = 25 m
Time (t) =?
The time taken for the echo of the sound to the bat can be obtained as follow:
v = 2x / t
330 = 2 × 25 / t
330 = 50 / t
Cross multiply
330 × t = 50
Divide both side by 330
t = 50 / 330
t = 0.15 s
Thus, it will take 0.15 s for the echo of the sound to the bat
if the pointy thingy in your compass is pointing north, that means it's being (pulled toward) something near Earth's north pole
Answer:
10,000
Explanation:
200,000/20 = power needed
200,000/20 = 10,000
Hope this Helps!
