What part of an electrical circuit is intended to limit the<br> maximum current through the circuit?
stepladder [879]

Answer:The charge passing through the circuit always passes through an appliance (which acts as a resistor) or through another resistor, which limits the amount of current that can flow through a circuit. Appliances are designed to keep current at a relatively low level for safety purposes.

WHICH SIGNAL IS TRANSFERRED IN ELECTRICAL WIRE ?
Dvinal [7]

Answer:

electrical signal is transferred in electrical wire

Explanation:

electrical signals are transmitted between segments of the axon by successive opening of channels down the atonal membrane with negative and positive charge fluxing on either side of the membrane through selectively permeable chlorine , sodium or potassium channels.

hope this ans may help you.

The rectangular region of the xy plane shown has nonuniform surface charge density σ = σ0 (1+ y b), where σ0 is a constant. Find
sergiy2304 [10]

Answer:

This is net charge on the surface  is  Q = σ₀ x (y + 2by²)

Explanation:

The surface charge density is defined as the amount of charge Q per unit area A

       σ = dq / dA

       dq = σ dA

Since the surface is a rectangular region we use an xy coordinate system so the area difference  

      dA = dxdy

      dq = σ dx dy

 We replace, evaluate the integral

        ∫ dq = ∫ σ₀ (1 + yb) dxdy

realizamos laintegral de dx

        Q -0 =σ₀ ∫ (1 + yb) (x-0)   dy

Where we evaluate We must recognize that the charge Q must be zero by the time X = 0 and Y = 0. At the starting point Q = 0 for x = 0

 

We perform the other integral (dy)

        Q = σ₀ x (y + 2y² b)

Evaluated between Y = 0 and Y = y

      Q = σ₀ x (y + 2by²)

This is net charge on the surface

Suppose an elephant has a mass of 2850 kg. show answer No Attempt How fast, in meters per second, does the elephant need to move
Bad White [126]

Answer:

1.23 m/s

Explanation:

The kinetic energy of the sprinter is:

KE = 0.5 * m(s) * v²

KE = 0.5 * 77 * 7.5²

KE = 2165.63 J

If the KE of the sprinter and the KE of the elephant are equal, hence:

2165.63 = 0.5 * m(e) * v²

2165.63 = 0.5 * 2850 * v²

=> v² = 1.52

v = √(1.52)

v = 1.23 m/s
