In up milling the cutter rotates clockwise when cutting the workpiece from right to left. in down milling the cutter rotates clockwise when cutting the workpiece from left to right
the wavelength equation is
speed (of light in this
case)= wavelength (m) x frequency
3x10^8m/s / .07m = f
frequency= 4 285 714 286
hertz
b) Total distance= 4.8 km
(4,800 m)
Speed = 3x10^8 m/s
d=st
t= d/s
t= 4,800 m/3x10^8m/s
<span>t= 1x10^-5 seconds</span>

The height above the ground from where the skier start is 11.5 m.
<h3>
Conservation of energy</h3>
The height above the ground from where the skier start is determined by applying the principle of conservation of energy as shown below;
P.E = K.E
mgh = ¹/₂mv²
gh = ¹/₂v²

Thus, the height above the ground from where the skier start is 11.5 m.
