Answer:

The answer is 4N or B

Explanation:

Just the equation W = F x D.

We have W = 8 J and D = 2 m using algebra ....

8J/2m = F ... F = 4.

a freight train travels at v=60(1-e^-t) ft/s, where t is the elapsed time in seconds. Determine the distance traeled in tree sec
lesantik [10]

Answer

given,

v = 60(1-e^{-t})\ ft/s

t = 3 s

we know,

v = \dfrac{dx}{dt}

a = \dfrac{dv}{dt}

position of the particle

dx = v dt

integrating both side

\int dx =\int 60(1-e^{-t}) dt

x = 60 t + 60 e^{-t}

Position of the particle at t= 3 s

x = 60\times 3+ 60 e^{-3}

 x = 182.98 ft

Distance traveled by the particle in 3 s is equal to 182.98 ft

now, particle’s acceleration

a = \dfrac{dv}{dt}

a = \dfrac{d}{dt}60(1-e^{-t})

  a = 60 e^{-t}

at t= 3 s

  a = 60 e^{-3}

    a = 2.98 ft/s²

acceleration of the particle is equal to 2.98 ft/s²

What is current of 12 ohm? help me pleasee​
Ne4ueva [31]

Answer:

Current for 12 ohms = 2.5

Explanation:

Ohm's Law:

Voltage = IR

Current = V/R

Resistance = V/I

Therefore, current = 30V/12 Ohms

30/12 = 2.5

So current for 12 ohms = 2.5

I hope this helps :>

What is the purpose of using conductors in a circuit?
Aleonysh [2.5K]

Answer:

Conductors and insulators are both important in the field of electronics. Electrical conductors allow electric current to flow easily because of the make up of their atoms. In a conductor, the outer electrons of the atom are loosely bound and can freely move through the material when an electric charge is applied.
