Answer:
a. Speed = 342.5 meters per seconds.
b. Wavelength = 2.0 meters
Explanation:
Given the following data;
Distance = 100m
Time = 292 milliseconds to seconds = 292/1000 = 0.292 seconds
Frequency = 171 Hz
a. To find the speed of sound in air;
Speed = distance/time
Speed = 100/0.292
Speed = 342.5 m/s
b. To find the wavelength;
Wavelength = speed/frequency
Wavelength = 342.5/171
Wavelength = 2.0 m
Scientific evidence supports a new idea
1. For the first box, the answer is TIME
2. For the second box, the answer is VELOCITY
Hope this helps :)
Answer: A
Explanation:
I got it right just wanted to have a letter answer for my fellow USA TestPrep people
Answer:
Energy and another nucleus of the new element/particle.
Explanation:
A nuclear decay is an radioactive decay where the nucleus of an atom becomes unstable and loses energy through emitting radiations.For example, there is an alpha decay that release an alpha particle called helium-4, a beta decay that involve releasing a beta particle which normally occurs in a nucleus that has more neutrons than protons.Other decays are the gamma decay,electron capture and the spontaneous fission.Nuclear decay produces a lot of energy and radiations that could harm human cells if exposed.
