Engineering
1 answer:
Furkat [3]3 years ago
6 0

Answer: True

Explanation: Closed loop relies on feedback from PNS to make modifications in the movement, open loop allows action in the absence of feedback, 2. ... Closed loop can change the initial commands, open loop can not change the initial commands.

What is a combination circuit? A combination circuit:
Anon25 [30]

Answer:

Combination circuit; The basic strategy for the analysis of combination circuits involves using the meaning of equivalent resistance for parallel branches to transform the combination circuit into a series circuit.

Example:

The use of both series and parallel connections within the same circuit. In this case, light bulbs A and B are connected by parallel connections and light bulbs C and D are connected by series connections. This is an example of a combination circuit.

the uniform bar (mass m and length l ) is leaning against a wall. the coefficient of static friction between all surfaces and th
zaharov [31]

The coefficient of static friction is the ratio of the maximum static friction force (F) between the surfaces in contact before movement commences to the normal (N) force.

<h3>What is coefficient of static friction formula?</h3>
  • The friction coefficient is the ratio of the normal force pushing two surfaces together to the frictional force preventing motion between them.
  • Typically, it is represented by the Greek letter mu (). In terms of math, is equal to F/N, where F stands for frictional force and N for normal force.
  • The ratio of the greatest static friction force (F) between the surfaces in contact before movement starts to the normal force (N) is known as the coefficient of static friction.
  • A body and a surface have static and kinetic friction coefficients of 0.75 and 0.5, respectively. The body is forced to slide with a constant acceleration that is equal to A. g4 by applying a force.

Modify the one-dimensional continuity equation to include rainfall over the free surface
KonstantinChe [14]

The rainfall run off model  HEC-HMS is combined with river routing model. They are used for simulating the rainfall process.

Explanation:

The HEC - HMS rainfall model is used for simulating the rainfall runoff process. In this study the soil conservation service and curve number method is used to calculate the sub basin loss in basin module.

It provides various options for providing the rainfall distributions in the basin. It has the control specification module used to control the time interval for the simulations.

The one dimensional continuity equation is

бA / бT + бQ / бx= 0
