Answer: Wavelength is related to light and also related to energy. The shorter the wavelengths and the higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy. The energy equation is E = hν.

You want v2 = v1 + at
v is measured in m/s, a in m/s2, and t in s.
the dimensions multiply like algebraic quantities.
so because v2 is measured in m/s, then (v1 + at) has to come out in m/s
the units for (v1 + at) are (m/s) + (m/s2)(s)
time "s" cancels out one acceleration "s", so it comes ut to (m/s) + (m/s), which = (m/s).
if you had (v1t + a), then you would have (m/s)(s) + (m/s2) which = (m) + (m/s2), which doesn't work.
<span>The equation to be used here would be:
v = u - gt
where u is the initial speed, g is the acceleration due to gravity and t is the time it takes
a)
u = 28 m/s, g = 9.8 m/s^2, t = 2s
v = 28 m/s - 9.8 m/s^2 * 2s = 8.4 m/s
after 2 s the lava bomb is still travelling upwards
b)
u = 28 m/s
g = 9.8 m/s^2 t = 3s
v = 28 m/s - 9.8 m/s^2 * 3s = -1.4 m/s after 3s the lave bomb is travelling downwards</span>
They undergo internal fertilization. They lose their tails as adults. They have wet, moist skin. They have long, strong legs. They begin life with gills.
