Heya how have you been doing
Answer:
Redshift, or lower power
Explanation:
doppler effect
waves get stretched when you are moving away from something, and squished when you are moving towards it. Imagine you have a long, bent wire. if you stretch out the wire, the wavelength becomes longer. This also applies to sound.
Go with the last one because you need potential energy for kinetic energy
Answer:
44.4cm
Explanation:
glass has an index of refraction .n = 1.54
radii of curvature of 40 cm R1 = 40 by
radii of curvature of 600 cm R2 = 60
Now, by lens maker formula
1/f = (n - 1) (1/R1 - 1/R2)
Putting in the given values for n = 1.54 , we get f = 22.2
f = 1 / 0.0225
f = 44.4cm
so, focal length in air will be = 44.4 cm
Answer:
New Madrid earthquakes are centered in a plate interior, meaning they were intraplate earthquakes.
Explanation:
The 1811-1812 new madrid earthquakes were different from most california earthquakes because the New Madrid earthquakes were centered in a North American plate interior caused by stress within the plates.
