Answer:
A. Adjusts how far down the piston travels
Explanation:
This type of engine changes the possition of the piston in order to modify the compression chamber volume and therefore the compression ratio of the engine. The volume of the chamber is proportional to the run of the piston (how far down the piston travels)
This engine is used to achive the optimal compression rate in each individual stage.
Answer:
The speed of all ocean waves is controlled by gravity, wavelength, and water depth. Most characteristics of ocean waves depend on the relationship between their wavelength and water depth. Wavelength determines the size of the orbits of water molecules within a wave, but water depth determines the shape of the orbits

PLEASE GIVE ME BRAINLIEST
None of those choices is a device commonly used to detect
the presence of a static electric charge. One of them is a
process or technique, and is not even a 'device'.
A couple of them might be jerry-rigged to detect charge, but
that is not their intended purpose or design, and it would take
some ingenuity. They're certainly not "commonly used" in that
application.
-- Compass . . . a device that detects the presence of a magnetic
field and displays its direction.
-- Voltmeter . . . a device that displays the presence and measures
the magnitude and direction of electric potential
difference between two points.
-- Electrophoresis . . . a method of separating macro molecules
according to their size.
-- Galvanometer . . . a device used to detect the presence and
measure the magnitude and direction of
small electric currents.
Answer:
Wood Resistance = 0.18 m².°C/W
Explanation:
The formula for heat flow in terms of thermal resistance is:
Q/A = ΔT/R
R = AΔT/Q
where,
R = Total Resistance = Resistance of Concrete + Resistance of wood = Resistance of wood + 0.26 m².°C/W
A = Surface Area of Wall = 3.2 m x 4.7 m = 15.04 m²
ΔT = Difference in temperature = 16°C - 2°C = 14°C
Q = Heat Flow = 476 Watt
Therefore,
0.26 m².°C/W + Wood Resistance = (15.04 m²)(14°C)/(476 W)
Wood Resistance = 0.44 m².°C/W - 0.26 m².°C/W
<u>Wood Resistance = 0.18 m².°C/W</u>
