Absolute, Atmospheric, Differential, and Gauge Pressure
Y: Radio
Z: Gamma
because gamma has a higher frequency then radio, therefore the higher the frequency the shorter the wavelength
Answer:
What is a Control Group? The control group (sometimes called a comparison group) is used in an experiment as a way to ensure that your experiment actually works. It's a way to make sure that the treatment you are giving is causing the experimental results, and not something outside the experiment
Explanation:
Earths atmosphere filters iyself every 6 months...ozone layer keeps in its concentration
Answer:
Explanation:
Intensity of a wave is inversely proportional to distance from source
I ∝ 1 / r
I is intensity , r is distance
I₁ / I₂ = r₂² / r₁²
ratio of intensity = 44² / 14²
= 9.87
intensity of earthquake of first place will be 9.87 times that of second place .
