Answer:
1. Primary or P waves are push and pull waves
2. Secondary, S or Shear Waves are also called transverse wave
3. L or surface waves reach the earth's surface after P and S waves
Emf e = 11
r 1 = 3.0
r 2 = 3.0
r 3 = ?
The two in parallel are equivalent to 3 • 3/6 = 1.5 Ω
To have 2.4 volts across them, the current is I = 2.4/1.5 = 1.6 amps. and the unknown R = (11–2.4) / 1.6 = 5.375 Ω or 5.4 Ω
Answer:
10.1 N
Explanation:
Your answer is 10.1 N, I don't actually know how to do it but I hope it helps.
It is letter b which is Global Warming
Answer:
Light with a wavelength of 100 nm is completely absorbed by the atmosphere. True
Light with a wavelength of 400 nm has the color of red. False
Light with a wavelength of 280 nm is in the ultraviolet region. False
Explanation:
Light of wavelength 0-100nm can be absorbed by the earths atmosphere
Ultraviolet light ranges between 320-400nm hence the statement above is false.
The wavelength of red colour is around 620-700nm hence the statement above is false.
