The magnetic field at a point 1.2 m from the axis has a magnitude of 7.0 × 10^–6 T

<h3>Further explanation </h3>

Maxwell's equation is a set of coupled partial differential equations that together with the Lorentz force law form the classical electromagnetism, classical optics, and electric circuits.

Integral form in the absence of magnetic or polarizable media are Gauss' law for electricity, Gauss' law for magnetism, Faraday's law of induction, Ampere's law

A 0.70 m radius cylindrical region contains a uniform electric field that is parallel to the axis and is increasing at the rate 5.0* 10^{12} v/m.s  The magnetic field at a point 1.2 m from the axis has a magnitude of?

The Maxwell’s law of induction is as follows. Consider the charging of our circular  plate capacitor , B field also  induced at  point 2.  When capacitor stops charging  B field disappears.

By using the Maxwell’s law of induction for a circle of radius r.

2\pi rB = \epsilon_{0}\mu_{0}\pi r^2 \frac{dE}{dt} , B = \frac{1}{2}  \epsilon_{0}\mu_{0}r\frac{dE}{dt} = 7*10^{-6}T

Magnetic fields are effects that are being produced by electric currents that are present in a material. It is characterized by both magnitude and direction so it should be a vector quantity. Magnetic field is represented by B and is proportional to the current that is passing through. It is equal to the product of a constant, uo, and the current divided by the product of 2(pi) and the distance from the wire. Base from the problem statement, there was no value of current mentioned. Therefore, the magnetic field would be zero. No magnetic fields are produced when current is zero.

Usimov [2.4K]

Answer:

v_{f}  = 3289.8 m / s

Explanation:

This exercise can be solved using the definition of momentum

     I = ∫ F dt

Let's replace and calculate

     I = ∫ (at - bt²) dt

We integrate

      I = a t² / 2 - b t³ / 3

We evaluate between the lower limits I=0  for t = 0 s and higher I=I for t = 2.74 ms

      I = a (2,74² / 2- 0) - b (2,74³ / 3 -0)

      I = a 3,754 - b 6,857

We substitute the values ​​of a and b

      I = 1500 3,754 - 20 6,857

      I = 5,631 - 137.14

      I = 5493.9 N s

Now let's use the relationship between momentum and momentum

      I = Δp = m v_{f} - m v₀o

      I = m v_{f}  - 0

     v_{f}  = I / m

    v_{f}  = 5493.9 /1.67

    v_{f}  = 3289.8 m / s

A box is at rest on a ramp at an incline of 22°. The normal force on the box is 538 N.
fomenos

Answer: 580 N

Refer to attached figure.

The angle of inclination is 22 degrees

weight (gravitational force) acts downwards.

Normal force is a contact force which acts perpendicular to the point of contact.

The horizontal component (mg cos 22 ) balances the normal force and the vertical component balances the frictional force.

Gravitational force on an object = mg

The normal force N= mg cos 22

\Rightarrow mg =\frac{N}{cos22}=\frac{538 N}{0.927}=580 N

A beam of electrons moves at right angles to a magnetic field of 4.5 × 10-2 tesla. If the electrons have a velocity of 6.5 × 106
defon

Answer:

4.7\cdot 10^{-14}N

Explanation:

For a charge moving perpendicularly to a magnetic field, the force experienced by the charge is given by:

F=qvB

where

q is the magnitude of the charge

v is the velocity

B is the magnetic field strength

In this problem,

q=1.6\cdot 10^{-19} C

v=6.5\cdot 10^6 m/s

B=4.5\cdot 10^{-2} T

So the force experienced by the electrons is

F=(1.6\cdot 10^{-19}C)(6.5\cdot 10^6 m/s)(4.5\cdot 10^{-2} T)=4.7\cdot 10^{-14}N

Tju [1.3M]

By law of refraction we know that image position and object positions are related to each other by following relation

\frac{\mu_1}{h_o} = \frac{\mu_2}{h_i}

here we know that

\mu_1 = 1.473

h_o = 5 cm

\mu_2 = 1

now by above formula

\frac{1.473}{5} = \frac{1}{h_i}

h_i = 3.39 cm

so apparent depth of the bottom is seen by the observer as h = 3.39 cm
