Answer: <u><em>A</em></u>
Explanation:
A pneumatic control system uses compressed air as a method of control for HVAC systems. ... Each senor responds to changes in temperature, humidity, and static pressure as examples, to provide feedback in a control loop to open or close the actuator to meet the control set point.
Answer:
Fc = 1.7x10^-4 N
Explanation:
Convert everything to proper units:
m = 25mg = 2.5x10^-5 kg
r = 17.6cm = 0.176m
v = 110cm/s = 1.1m/s
the formula for centripetal force is Fc = mv^2 / r
Plug everything and solve for Fc;
fc = (2.5x10^-5)(1.1^2) / 0.176
Fc = 1.7x10^-4 N
Answer:
the swing on the right is more likely to break
since the vertical component of the tension of the rope has to balance the weight. ie. the resultant tension in the rope is greater
Explanation:
Hipparchus had observed and discovered the precession motion of Earth. Due to the precession the axis of the Earth will gradual shift in a cycle of 25772 years. That means the axis will point towards different stars in the celestial sphere and our pole stars will change.
Because of this change in the axis the apparent position of Sun with respect to the background constellation (sun signs) regresses. Because of which the dates associated with the sun signs will be wrong.
