Answer:
"where crests and troughs have their maxima at the same time"
Crests and troughs are 180 deg out of phase and when they have their maxima at the same time and place, their net contribution will be zero"
Answer:
Iris
Explanation:
The pupil is where the light enters the eye, however, the iris is pupil tissue and is the one who regulates the amount of light that it lets through.
The iris opens or closes to allow a greater or lesser flow of light through the pupil.
In summary, the iris is responsible for regulating the amount of light that enters the eye.
<span>Youll need to use Wiens Displacement Law:\[T=\frac{ 2.8978*10^{-3}m∙K }{ \lambda _{\max} }\]Note that the units of the constant are meter∙Kelvin, so youll need to convert 350nm to meters.</span>
Answer:
The distance he moved the soil is 32.97 m.
Explanation:
Given;
force exerted on the wheelbarrow, F = 185 N
work done in moving the soil, w = 6.1 kJ = 6100
The work done in moving the soil is given as;
Work done = force x distance he moved the soil
W = F x d
d = W / F
d = (6100) / (185)
d = 32.97 m
Therefore, the distance he moved the soil is 32.97 m.
Explanation:
At the top of the the ball's trajectory, there is only the horizontal component of the initial velocity, which is so the kinetic energy of the ball at this point is
