Answer: The correct answer is D.

Explanation:

In the given problem, Jenna built a completed electrical circuit. From the given circuit diagram, it can be concluded that the electrical energy can be transformed into both heat and light.

The electrical energy is used to light bulb and some of the energy is lost due to heat dissipation.

The wires will get heated up and after some time, the bulb will also get heated up. There is a dissipation of the electrical energy in the form heat.

Therefore, the correct answer is D.

Answer: The object moves with constant velocity

Explanation:

In this velocity vs time graph we're dealing with Ap physics or regents physics. If we look at the slope we can see it is constant or not changing. Even so lets check the other answers and prove them wrong

The objects speed increases: This is wrong because the line shows a steady 5m/s with no change

The object is in free fall: If the object was in freefall the speed would be increasing as a result of acceleration due to gravity

The object moves with a constant speed: This seems to be the case since the slope or line doesn't change at all

The object stays at rest: Can't be right because the object is at a speed of 5m/s so we know its moving at least

The objects speed decreases: Again the line isn't going up or down so we can't say speed increases or decreases

Two long, straight wires are separated by a distance of 32.2 cm. One wire carries a current of 2.75 A, the other carries a curre
Igoryamba

Answer:

a)\frac{F_1}{L}=1.95*10^-^5N

b)\frac{F_2}{L}=1.95*10^-^5N

Explanation:

From the question we are told that:

Distance between wires d=32.2

Wire 1 current I_1=2.75

Wire 2 current I_2=4.33

a)

Generally the equation for Force on l_1 due to I_2 is mathematically given by

F_1=I_1B_2L

Where

B_2=Magnetic field current by I_2

B_2=\frac{\mu *i_2}{2\pi d}

Therefore

F_1=I_1B_2L

F_1=I_1(\frac{\mu *i_2*l_1}{2\pi d})L

\frac{F_1}{L} =\frac{4*\pi*10^{-7}*2.75*4.33*100 }{2*\pi*12.2 }

\frac{F_1}{L}=1.95*10^-^5N

b)

Generally the equation for Force on I_2 due to I_1 is mathematically given by

F_2=I_2B_1L

Where

B_1=Magnetic field current by I_2

B_1=\frac{\mu *I_1}{2\pi d}

Therefore

\frac{F_2}{L} =I_2(\frac{\mu *I_1*I_2}{2\pi d})

\frac{F_2}{L}=1.95*10^-^5N
