What is the mechanical advantage of the simple machine pictured? A. 8.3
B. 14.7
C. 1.9
D. 20.4

Explanation:

The simple machine in the attachment is a screw; so, I'll list the given parameters using related terms

Given

Radius of the screw (r) = 2.6m

Pitch (P) = 0.8m

Required

Calculate the Mechanical Advantage (M.A)

M.A is calculated as thus;

Substitute 2.6 for r;  0.8 for P and 3.14 for

From the list of given options, the approximated answer is D. 20.4

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
