Ice Age or glacial period refers to the extended period of well-below-average temperatures. It is a prolonged period where reduction in the temperature of the Earth’s surface and atmosphere are caused by the expansion of continental and polar ice sheets and alpine glaciers. Usually this phenomenon occurs in the northern and southern hemispheres where extensive ice sheets are seen most.

Answer:
8
Explanation:
IMA of Wheel and Axle :
IMA = Radius of wheel / Radius of axle
Radius of wheel, radius of handle, R = 1.6 cm
Radius of axle, radius of shaft, r = 0.2 cm
IMA = Radius of wheel / Radius of axle
IMA = 1.6 / 0.2
IMA = 8
Hence, the ideal mechanical advantage is 8
The speed of a wave measures how far one particular crest (or trough) moves in a given amount of time. The speed of the wave changes according to the following equation:
v = λ
* f
According this equation, it follows that as the speed and length of a wave decreases, the wave grows higher (the higher the frequency).
