If this inclined plane moves 3 cm to the left how high will it lift the object?
There is not sufficient information for a proper answer to the question. We need to know either the inclination angle of the plane or the length and height of the plane, which will give the inclination. Also if the plane rises to the right of the object and the object is already on the plane, then the object will be lower instead of higher.
How does inclined planes make work easier?
it reduces the amount of power and distance needed to make it more efficient. ******************************* An inclined plane, also known as a ramp, allows us to roll any wheeled platform (such as a bicycle, a wheelchair, or a car) to a higher or lower elevation, without having to pick it up.
How can you stabilize and unstable ship and correct a negative GM at the same time?
Change hull form (which is impractical) Lower Center of Gravity. (i.e. shifting heavy weights to a lower position)
What causes systematic error?
Improper calibration of the measuring instrument. If the measuring instrument is not at zero prior to measuring the object you will get a systematic error which, is a value either always higher or always lower then the actual value of the object.
How do you find the angle of depression?
The angle below horizontal that an observer must look to see an object that is lower than the observer. Note: The angle of depression is congruent to the angle of elevation (this assumes the object is close enough to the observer so that the horizontals for the observer and the object are effectively parallel; this would not be the case for an astronaut in orbit around the earth observing an object on the ground).
