How does battery generate electric current in a circuit?

Physics
1 answer:
sveticcg [70]3 years ago
3 0

Answer:

C. It creates negative electric charges and pushes them into the circuit

Explanation:

A battery has three main parts. The Cathode (Positive), the Electrolytes (energy source), and the Anode (negative). The anode takes energy from the electrolytes and creates more electrons. And because subatomic particles with the same charge don't like being in the same place, they move through the circuit to reach the cathode because opposites attract.

I hope this helps!

a wire carries a current of . the wire is formed into a single circular loop and placed in a magnetic field of intensity . find
Vika [28.1K]

The maximum torque that can act on the loop is 7.875 N-m.

Torque:

Torque is a twisting or turning force that tends to cause rotation around an axis, which might be a center of mass or a fixed point. Torque can also be thought of as the ability of something that is rotating, such as a gear or a shaft, to overcome turning resistance.

The formula of torque:

Torque(T) = I B A

B = magnetic field of intensity

I = current =

A = area of the wire

l = length of the wire

l = 2πr

r = l/2π

A = πr²

   = π(l/2π)²

   = l²/4π

T = l²/4π IB

   =( 1/4π) BIl²

    = (1/4π) 0.30 × 150 ×× 2.20

    = 7.875 N-m

Therefore the torque is 7.875 N-m.

Which of the following atoms is least likely to form chemical bonds with other atoms
wariber [46]
The atom that would least likely form chemical bonds with other atoms would be C. A neon containing 4 valence electrons, this is because neon itself is an inert gas, it would not necessarily react as it already possess the maximum number of electrons needed to achieve stability and have a full octet, even if it is forced to obtain 4 valence electrons it would not react with other atoms.

A supply plane needs to drop a package of food to scientists working on a glacier in greenland. the plane flies 100 m above the
pishuonlain [190]

The package should be dropped <u>678 m</u> short of the target.

A package dropped from a plane which is moving at a speed v, has a horizontal velocity equal to the horizontal velocity of the plane. It has a parabolic trajectory, traversing a horizontal range x while it falls through a vertical height y.

The package has no initial vertical velocity, and it falls through a height y under the action of the acceleration due to gravity g.

Use the equation,

y=\frac{1}{2} gt^2

Write an expression for t, the time taken for the package to fall through y.

t^2=\frac{2y}{g}

Substitute 100 m for y and 9.81m/s² for g.

t^2=\frac{2y}{g}\\ =\frac{2(100m)}{9.81m/s^2} \\ =20.39s^2\\ t=4.52s

In the time t  the package travels a horizontal distance x. The horizontal velocity of the package remains constant, since no force acts along the horizontal direction.

Therefore, the horizontal distance traveled by the package is given by,

x=vt\\ =(150m/s)(4.52s)\\ =678m

If the package is released <u>678m</u> before the target, the package would reach the scientists working in Greenland.

You start at (8, 1). You move right 2 units. Where do you end?
ivann1987 [24]

I'm pretty sure should be shifting your transformation those two units to the right from the original function.

Moving right = subtracting

Moving left = adding
