A pressure altimeter is an instrument that measures the outside air pressure, and then uses this pressure reading to estimate the height. Suppose Captain Bob flies at fixed pressure altimeter reading (which really means he's flying at constant pressure) into an upper-level trough. The actual height of Bob's plane would then likely.

Increase

Explanation:

A pressure altimeter is an instrument that measures the outside air pressure, and then uses this pressure reading to estimate the height. If Captain Bob flies at fixed pressure altimeter reading (which really means he's flying at constant pressure) into an upper-level trough. The actual height of Captain Bob's plane would then likely increase because he's flying at constant pressure.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

f is prop to m1xm2 double m1 double force
