Mass, m = 85 kg, velocity = 15 m/s, radius = 20m.
Centripetal force = mv²/r
F = 85*15²/20 = 85*15*15/20 = 956.25 N
Answer: Wavelength increases and frequency decreases.
Explanation:
Electromagnetic spectrum is formed of radiations varying in frequency and wavelength like gamma rays, radio waves, UV rays, visible, and microwaves. We know that wavelength is proportional to frequency. Since the wavelength is proportional to frequency, the wavelength increases.
Answer:
ocean wave
Explanation:
ocean waves are not a wavelength but produced from the pull of the moons gravitational pull
I would say B, false, because something that is biodegradable is an object or dead organism that can be degraded by a living thing near it. Since a compost pile is not a living thing and the question does not give any additional information about organisms near the leaf, I would say this is false.
