uhm i think i don’t understand what it says but i can answer if it was English ! i also tried to translate it but it didn’t help !
<span>False. Laser transmissions and radio waves are both forms of electromagnetic radiation. Both travel at approximately 3.00 x 10^8 meters per second. This is the case because wavelength and frequency are directly proportional to this value. Although laser light has a shorter wavelength than radio waves, it will travel at the same speed because the frequency will be greater.</span>
Answer:
3) 255.04 m
Explanation:
Given:
v₀ = 115 km/h = 31.944 m/s
v = 0 m/s
a = -(4 m/s) / 2s = -2 m/s²
Find: Δx
v² = v₀² + 2aΔx
(0 m/s)² = (31.944 m/s)² + 2 (-2 m/s²) Δx
Δx = 255.11 m
Closest answer is option 3.
Answer:
I would guess C. Refraction, since thats where waves bend.
