Power in most circuits could be analysed and broken down into two categories
-Power dissipated by resistive components
-Power delivered by the electrical sources.
If you are working with Alternate current (AC) sources, the analysis of the power consumed in the circuit will deal with complex numbers and the introduction of new terms such as active, reactive and apparent power.
All this depending on the frequency and the components used in the circuit.
Sinc the elevator is moving at constant velocity, it experience no net force and thus no net acceleration is experienced by the elevator. a=0ms^-2
Answer: 5
Explanation: rise over run. 25/5 = 5
A. is the answer for this question
Explanation:
1) the diagonal force times the sine of the angle it makes will give you the vertical component or y component . use this to get the vertical components of all the diagonal forces . add all the vertical components as well as the vertical forces together
2) the diagonal force times the cosine of the angle it makes gives the horizontal component or x component. do this to get the x component of all the diagonal forces.
add all the x components as well as the horizontal forces together to get the final x component
3)using the triangle of vectors, the resultant force is calculated
sum of y component = 3.2N
sum of x component= 5.7N
resultant force = 6.5N
