What particles carry electric current in metal wires?
A. amperes
B. protons
C. electrons
D. neutrons

Answers

Answer 1

Electric current in metal wires is carried by free electrons. due to any variations.

Electrical charge travels through a conductor when a potential difference is put across it, and electrical current is a measure of how much electrical charge passes through a conductor in a given amount of time.

Electrons and protons are both present in an atom in equal numbers. So, in general, atoms are electrically neutral. There will be an attractive force acting between the electrons and protons because they are attracted to one another due to the positive charges of the core nucleus's protons and the negative charges of the circling electrons. A variety of electrons organise themselves in distinct circling shells that are spaced apart from the nucleus in an atom.

Answers

Answer:

To write mesh equations for a circuit, we need to identify the "meshes" or closed loops in the circuit and write an equation for each mesh in terms of the currents flowing through the various components in the mesh.

In this circuit, there are two meshes:

Mesh 1: 8 Ω, 30 V, 8 Ω, 40 V, 8 Ω, 32 V

Mesh 2: 12 V, 6 Ω, 10 Ω, 10 Ω, 6 Ω, 24 V

We can write the equations for each mesh as follows:

Mesh 1: 8 Ω * I1 + 8 Ω * I1 + 8 Ω * I1 = 30 V + 40 V + 32 V

Mesh 2: 12 V - 6 Ω * I2 - 10 Ω * I2 + 10 Ω * I2 - 6 Ω * I2 = 24 V

In these equations, I1 and I2 represent the currents flowing through each mesh. Solving these equations, we can find the values of I1 and I2.

How is SWL of wire sling calculated?

Answers

Square the diameter of the wire rope, then multiply by 8 to determine the SWL of the wire sling.

The diameter of the rope must be squared and multiplied by 8 kgs to yield the SWL. Thankfully, the majority of wire rope suppliers will provide you this estimate. Depending on the wire rope's diameter and weight, the safe working load will vary.

For many years, the concept of Safe Working Load (SWL), particularly in relation to equipment that carries loads, has served as the cornerstone of engineering. A "safe" load that could be lifted or carried was traditionally thought to be the minimal breaking load of a component divided by an adequate safety factor.

All industries in Australia employed Safe Working Load (SWL) for cranes, hoists, and winches, and regulation made reference to it.

when a unit load is secured to a pallet, it is more difficult for pilferage to take place. true false

Answers

Answer: True

Explanation:

When a unit load is secured to a pallet, it is more difficult for pilferage to take place. This is because the unit load is more securely attached to the pallet, making it more difficult for someone to remove items without being noticed. Additionally, securing a unit load to a pallet can also make it easier to transport and handle, which can further reduce the risk of pilferage.

Answer:

It is TRUE.

Explanation:

When a unit load is secured to a pallet, it is more difficult for pilferage to take place.

a certain 25-hp three-phase induction motor operates from a 440-v-rms (line-to- line) three-phase source. the full-load speed is 1750 rpm. the motor has a starting torque equal to 200 percent of its full-load torque when started at rated voltage. for an engi- neering estimate, assume that the starting torque of an induction motor is proportional to the square of the applied voltage. to reduce the starting current of the motor, we decide to start it with a line-to-line voltage of 220 v. estimate the starting torque with this reduced line voltage.

Answers

barhlejgkgo;hlhbdahbd;nbdzbds'bv

zsv

The estimated starting torque at 220V will be 0.25 * 200% = 50% of the full-load torque.

What is torque?

When a force is exerted to a lever arm at a certain distance from a center of gravity, torque, which is a rotational force, is produced. Torque is a unit of rotating force, and it is expressed by the equation = F r, where r is the distance of the lever arm from the pivot point, F is force, and is torque. Torque is a measurement of the speed at which a force may rotate an object. For instance, in an automobile, the engine produces torque that is transferred to the wheels and causes them to rotate, which in turn causes the car to drive.


An induction motor's starting torque is related to to square of the voltage source, therefore at 220V it will be (220/440)2 = 0.25 of that at 440V. In light of this, the predicted beginning force at 220V would be 0.25 * 200%, or 50% of the torque at full load.

The drag due to pressure is equal to viscous effects width = h 】Oh Determine (a) ravg in terms of the dynamic pressure pu2 (Ans:Tavg 0.06 pu2) (b) the drag coefficient of the bar. (Ans: CD = 2.40)

Answers

The average shear stress, Tavg, is equal to 0.06 pu2., Solving for the drag coefficient of the bar, CD, yields: 2.40.

What is shear stress?
An object experiences deformation whenever an external force acts upon it. if the force's direction is parallel to the object's plane. Along that plane, there will be a deformation. The object in this instance is under shear or tangential stress. It happens so when force vector components that are perpendicular to the material's cross-sectional area. The force vectors for normal/longitudinal stress will be parallel to the cross-sectional area that it affects.

(a) The average shear stress, Tavg, is equal to the dynamic pressure pu2 divided by the width of the bar, h. Therefore,
Tavg = pu2/h
Rearranging for the dynamic pressure pu2 yields:
pu2 = Tavg h
Substituting the given value of Tavg as 0.06 pu2 gives:
pu2 = 0.06 pu2 x h
Solving for h yields:
h = pu2/0.06 pu2
Therefore, the average shear stress, Tavg, is equal to 0.06 pu2.

(b) The drag coefficient of the bar, CD, is equal to the drag force (Fd) divided by the dynamic pressure (pu2) times the area (A) of the bar. Therefore,
CD = Fd/(pu2 x A)
Rearranging for Fd yields:
Fd = CD x pu2 x A
Substituting the given values for CD, pu2, and A gives:
Fd = 2.40 x pu2 x (h x L)
Solving for the drag coefficient of the bar, CD, yields:
CD = Fd/(pu2 x A) = 2.40

how does the velocity of streamflow change where a stream channel becomes wider but the discharge remains constant?

Answers

The velocity drops when a stream channel widens while the discharge stays constant.

The water in a stream moves at a certain speed. Distance and time are units (e.g., metres per second or feet per second). The stream's velocity is highest midstream, discharge close to the surface, and slowest along the bed and banks of the stream because of friction.

The ratio of cross-sectional area to wetted perimeter is known as the hydraulic radius, or HR or simply R. The cross-sectional area is equal to the width times the depth (W * D) for a hypothetical stream with a rectangular cross section (a stream with a flat bottom and vertical sides). The wetted perimeter for the same hypothetical stream would be calculated as follows: W + 2D = Depth + Width + Depth.

Research with many volunteers has determined that the mean number of $10 bills drawn is 68 with a standard deviation of 9.5, and the mean number of $20 dollar bills is 58, with a standard deviation of 7.8.(a) If D-the amount of money, in dollars, that a randomly-selected contestant grabs from the "$10 grab,"find the mean and standard deviation of D.Please help.
