What are the arrangement of resistors in series

Mama L [17]

Answer:

A chain

Explanation:

A series circuit is a circuit, where the resistors are arranged in a chain. They are aligned like this so the current only has one path to take. The current quantity is the same through each resistor.

If you ever have trouble remembering this you can think of a movie series which goes on and on and on. And remembering a parallel circuit is simpler because everything in the circuit will be parallel!

A projectile is fired horizontally from a gun that is 54.0 m above flat ground, emerging from the gun with a speed of 330 m/s. (

krok68 [10]

Explanation:

Given

height of building (h)=54 m

Projectile velocity=330 m/s

initial vertical velocity $(u_y)=0$

Initial horizontal velocity $(u_x)=330 m/s$

Time taken to cover vertical height of 54 m

$h=ut+\frac{gt^2}{2}$

$54=0+\frac{9.81\cdot t^2}{2}$

$t=\sqrt{\frac{54\times 2}{9.81}}$

t=3.31 s

Horizontal distance traveled in this time

$R_x=u_x\times t$

$R_x=330\times 3.31=1094.94 m$

Vertical component of velocity when it hits the ground

v=u+at

$v=0+9.81\times 3.31=32.47 m/s$

Forces that have a net force of zero the object will be still

earnstyle [38]

Answer:

No. It may be at rest or moves with a constant velocity.

Explanation:

The term "net force" refers to the vector addition of all forces acting on a defined body.

If the magnitude of the net is zero, then the acceleration of the given body would be zero. Hence, the given body may be moving with an unchanged velocity or at rest.

evablogger [386]

Answer:

Del(ρ/ε₀) - (Del)²E = -dμ₀J/dt

Explanation:

From Maxwell's fourth equation

Curl B = μ₀J + μ₀ε₀dE/dt (1) where the second term is the displacement current.

If the oscillation conduction current in the conductor is much larger than the displacement current then, the displacement current goes to zero. So we have

Curl B = μ₀J (2)(since μ₀ε₀dE/dt = 0)

From maxwell's third equation

Curl E = -dB/dt (3)

taking curl of the above from the left

Curl(Curl E) = Curl(-dB/dt)

Curl(Curl E) = (-d(CurlB)/dt) (4)

Substituting for Curl B into (4), we have

Curl(Curl E) = -dμ₀J/dt

Del(DivE) - (Del)²E = -dμ₀J/dt (5)

From Maxwell's first equation,

DivE = ρ/ε₀

Substituting this into (5), we have

Del(ρ/ε₀) - (Del)²E = -dμ₀J/dt
