You are given two infinite, parallel wires each carrying current I. The wires are separated by a distance d, and the current in
hoa [83]

Answer:F/L = μ0*I²/2πd

Explanation:

Both wires carries current of the value (I) and are separated by the distance (d).

The length of both wires is (L).

The first wire creates a magnetic field of the magnitude according to Bio-savart law

B=(Uo * I)/2πd

This magnetic field has the ability to exert a force F on the second wire.

This force (F) is given as

F=BIL* sin θ

θ here is 90 because the magnetic field is perpendicular to the length of the second wire.

Thus the value of sin 90 = 1

Hence F= BIL

But B=(Uo * I)/2πd.

We have that F= B=[(Uo * I)/2πd] x IL

Thus we have that F= [Uo* I²/2πd] x L

By rearranging, and bringing L to the left hand side of the equation, we have that

F/L = [Uo* I²/2πd]

:

change in potential energy , ∆Ep = 156.8Joules

Explanation:

Given;

Mass of object , m = 2.0 kg

Heights ; h₂ = 5.0m

h₁ = - 3.0m

To obtain

the change in potential energy, ∆Ep = ?

But,

∆Ep = mg∆h

Where;

m is the mass of the object (kg)

∆h = h₂ - h₁ is the change in height (m)

g is the acceleration due to gravity ( 9.80 m/s²)

Therefore,

the change in potential energy, ∆Ep = 2.0 × 9.80 × ( 5 - (- 3))

=156.8 joules

The chart below summarizes the forces applied to four different objects.
posledela

Answer:

C. Y

Explanation:

From Newton's second law of motion, we know that:

       Force = mass x acceleration

So;

      acceleration  = \frac{Force }{mass}  

 Therefore, to have the highest acceleration at a constant force, the mass must be low. Acceleration is inversely proportional to mass.

 

Y has the least mass and it will have the highest acceleration

The speed of light is 3.00 × 108 m/s in the vacuum of space. In a medium with what index of refraction would light travel slowes
Romashka [77]

Index of refraction can be calculated using the following formula:

n=\frac{c}{v}

where c=3 \times 10^8 \frac{m}{s} in a vacuum and "n" is the index of refraction.  So we must calculate our velocity by manipulating the index of refraction formula and isolate v and so:

v=\frac{c}{n}

We could go one by one and calculate the velocity or use logic.  If you divide by a larger number the output will be a smaller number.  Therefore, the answer would be n=1.62 is the slowest.

v=\frac{3 \times 10^8 \frac{m}{s}}{1.62}= 1.85185 \times 10^8 \frac{m}{s}

By that logic when n=1 light would travel the fastest of these four scenarios.  The key thing to understand about these problems is that the speed of light slows down as it goes through a medium, in a vacuum it's 3 x 10^ 8 m/s but as it goes through say air or water light slows down.
