Answer: A. X-rays
Explanation:
X-rays have the shortest wavelength and the highest energy of all of the options given.
Answer:
1.71 km
Explanation:
Convert 30 minutes to seconds:
30 min × (60 s / min) = 1800 s
Find the displacement:
0.95 m/s × 1800 s = 1710 m
Convert to kilometers:
1710 m × (1 km / 1000 m) = 1.71 km
Answer:
The new intensity decreases by a factor of 16.
Explanation:
The intensity of sound wave is given by :
P is power
A is area
or
, r is distance from the source
If the distance from the source is increased by a factor of 4, r' = 4r
So,
So, the new intensity decreases by a factor of 16.
I think the answer is discovery.
Answer: I think your answer would be true.
