read it carefuly you will understand why?????
Terminal velocity for a rain drop. assuming theses rain drops started to fall to the ground high enough to reach that speed. the stuff about the train and viewing the rain drops is i irrelevant. the question asked about the velocity of the drops compared to the ground
The correct answer is D. The bicycle is not in motion.
In the position-time graph we can see that de position of the cycle hasn't changed when the time has changed (e.g. when time changes from 2s to 3s, the position remains 3m). Therefore, we can conclude that the cycle is not moving, and therefore answer D. is correct.
Answer: First option
Explanation: The higher the frequency, the higher the energy.
λν=c where λ is the wavelength, ν is the frequency and c is the speed of light. So when wavelength decreases, v increases and so does energy.
An AM radio wave has a very long wavelength. It therefore has a very low frequency and low energy.
A light wave has a very short wavelength. It therefore has a high frequency and high energy.
The answer will be 206 N
reasoning:
you must recognize that the problem gave you the force due to weight on earth, which similarly on the moon will be F = mg, just a restatement of Newton’s Second Law.
so given the 1247 N on earth:
1247 = mg
1247 = m(9.8 m/s^2)
1247
—— = 127 kg for the mass
9.8
Now implement this equation with the known mass for moon’s gravity
F = (127kg)(1.62m/s^2)
F = 205.74 N or 206 N
Hope this helped!! Thank you for posting your question.
