Wait like the equations, or is there an actual question?
Equations are
Final velocity (Vf) = Initial velocity (Vi) + Acceleration (a) x Time (t)
Acceleration (a) = (Final velocity [Vf] - initial velocity [Vi]) divided by Time (t)
Force (f) = Mass (m) x Acceleration (a)
(Short version)
Vf = Vi + a(t)
a = (Vf - Vi) divided by t
F = m x a
In general, it is felt that ice ages are caused by a chain reaction of positive feedbacks triggered by periodic changes in the Earth's orbit around the Sun. The last ice age ended about 12,000 years ago. The next cooling cycle would be expected to start about 30,000 years or more into the future.
B is the correct answer
y=Asin(wt-kx)
A=amplitude
f=frequency
x=wavelength
since refraction is not on the wave formula,then option B is the correct answer
Kepler's second law of planetary motion says that the imaginary line
from the Sun to the planet sweeps out equal areas in equal periods
of time.
It's just as true of comets, asteroids, dwarfs, coasting space probes ...
anything in the solar system that's coasting in gravity, and not firing engines.
That's why a comet moves so fast when it gets near the Sun.
F = ma = -kx
m = 0.04 kg
x = -0.02m
a = 9.81m/s²
k = ma/x = 19.6 N/m
