Answer:

a

The point on the x-axis where the magnetic field will be zero is  [tex] d =  2.8 \ cm [/tex]

b

The point on the x-axis where the magnetic field will be zero is [tex]Z =  5.333 \  cm [/tex]Explanation:

From the question we are told that

   The first  current is [tex]I_1 = 5.5 \ A[/tex]

    The point of x- axis  intersection is  [tex]x =  -2.0 \  cm[/tex]

    The second current is  [tex]I_2  =  2.5  \  A[/tex]

     The point of intersection of the x-axis is  [tex]x =  2 .0  \  cm[/tex]

Generally given that the current of the two wires are same direction it means that the magnetic field in -between the wires will cancel out  giving zero

 So  

       [tex]B_1 -  B_2 =  0[/tex]

=>     [tex]B_1  =  B_2 [/tex]

=>      [tex]\frac{\mu_o *  I_1 }{2 *  \pi *  d }  = \frac{\mu_o *  I_2 }{2 *  \pi *  (4 -d) }[/tex]

Here  d is the of one wire to the point where the magnetic field is 0

and  given that the total distance in-between the wire is  D  =  2 =  2 =  4

Hence the distance of the other wire to the point where magnetic field is zero is  (4 - d)

So

     [tex]\frac{5.5}{ d}  =  \frac{2.5}{4-d}[/tex]

=>   [tex] 8d  =  22 [/tex]

=>   [tex] d =  2.8 \ cm [/tex]

So the point on the x-axis where the magnetic field will be zero is  [tex] d =  2.8  [/tex]

 Generally given that the current of the two wires are opposition direction it means that the magnetic field at a position which is not in-between the wire will be zero  

Let that position be  k

Let  the distance from the middle of both wires to k  be Z  

So

      [tex]\frac{\mu_o *  I_1 }{2 *  \pi *  ( 2 +  Z) }  = \frac{\mu_o *  I_2 }{2 *  \pi *  (Z -2) }[/tex]

=>  [tex]5.5 Z  - 11 =  5+ 2.5 Z[/tex]

=>    [tex]3Z  =  16[/tex]

=>    [tex]Z =  5.333\  cm[/tex]

Answer:

Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A. Because pressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m2.

Answer:

2.8 [N] at 163° counterclockwise from F1

Explanation:

To solve this problem we must perform a summation of forces on the X & y axes, these summations of forces must be equal to zero.

ΣFx = 0

- F1 + Fx = 0

- 2.7 + Fx = 0

Fx = 2.7 [N]

ΣFy = 0

- Fy + 0.8 = 0

Fy = 0.8 [N]

Now using the Pythagorean theorem we can calculate the magnitude of the force.

F = √(2.7)² + (0.8)²

F = 2.81 [N]

Now we can determine the angle using the tangent of the angle.

tan (α) = F2/F1

α = tan^-1 (0.8/2.7)

α = 16.5°

The force is in the fourth quadrant, so we need to subtract 180° from the calculated angle.

180 - 16.5 = 163.5°

Therefore the force is going to the 2.8 [N] at 163° counterclockwise from F1

Answer:

The mass of the second weight is approximately 0.477 kg

Explanation:

The given parameters are;

The acceleration experienced by the two weights = 3.8 m/s²

The mass of the first weight = 1.08 kg

The formula for the acceleration, a, of weights attached to a friction pulley, is given as follows;

[tex]a = \dfrac{g \cdot (M - m)}{M + m}[/tex]

Where;

a = The common acceleration of the two weights

g = The acceleration due to gravity = 9.81 m/s²

M = The mass of the first weight = 1.08 kg

m = The mass of the second weight

Therefore, we have;

[tex]m = \dfrac{M\cdot (g -a )}{g + a} = \dfrac{1.08\times (9.81 -3.8 )}{9.81 + 3.8} \approx 0.477[/tex]

The mass of the second weight = m ≈ 0.477 kg

The mass of the second weight ≈ 0.477 kg.

Answer:

to go to get a bike

Explanation:

Answer:

Explanation:

When dealing with optics, there is an incident wave, a reflected wave, and a transmitted wave. An incident wave is the initial wave coming out from the source, like a flashlight.

Then the reflected wave is created when the incident wave encounters an interface like a piece of glass. The reflected wave will reflect like you would expect.

Then, the transmitted wave is the wave which passes through the interface and continues.

So, a good question would be to ask for the value of the reflected wave function given an initial incident wave.

Another example entirely would be to look at the reflected wave on a tensioned string. If you shake a string up and down, a wave will be sent through it. Once hitting the wall, the wave will reflect back. A good question there is asking how the amplitude of the wave changed.

Explanation:

momentum is a vector quantity it has both magnitude and direction.

a vector diagram can be used to represent this principle of momentum conservation such as diagram uses an arrow to represent the magnitude and direction of the momentum vector for the individual objects before the collision and combined after the collision

The best representation of momentum vector is ; ( 4 )  An arrow

A momentum is a vector quantity with both magnitude and direction and it  simply represents  a mass ( object ) in motion. momentum is calculated as ;

P = mV .  where m = mass of object , v = velocity of object .

An arrow is a good representation of momentum vector because it has both mass and velocity when fired from bow.

Hence we can conclude that the best representation of momentum vector is an arrow.

a) It will take 24.4 second the planes to reach takeoff speed.

b) The minimum length of the runway must be  744.2 meter.

Acceleration is the rate at which speed and direction of velocity vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates.

Even if the speed is constant, motion on a circle accelerates because the direction is always shifting. Both effects contribute to the acceleration for all other motions.

Given parameters:

Acceleration of the plane: a = 2.5 m/s².

Final speed of the plane: v = 61 m/s.

Initial speed of the plane: u = 0 m/s.

Hence,  it will take the planes to reach takeoff speed = final speed/acceleration

= 61 m/s / 2.5 m/s²

= 24.4 second.

The minimum length of the runway must be = (final speed)²/(2×acceleration)

= ( 61)²/(2×2.5) meters
