The magnitude of the magnetic field on the axis of the ring (1/2)R from its center is [tex]\frac{\mu_{0} \omega qR^{2}}{2.5(\sqrt{5} )\pi R }[/tex].

The magnetic influence on moving electric currents, electric charges, and magnetic materials is described by a magnetic field, which is a vector field. A force acting on a charge while it travels through a magnetic field is perpendicular to both the charge's motion and the magnetic field.

The radius of the nonconducting ring is R.

The ring is uniformly charged q.

The ring rotates at a speed of ω.

The distance between the ring and its center is x = (1/2)R.

The magnetic field on a current loop's axis is given as follows:

[tex]B = \frac{\mu_{0} IR^{2}}{4 \pi (x^{2}+R^{2})^{\frac{3}{2}} }[/tex]

Now, [tex]I=\frac{q}{2 \pi /\omega}[/tex]

The magnetic field's strength at x = R/2 is:

[tex]B = \frac{\mu_{0} IR^{2}}{4 \pi (x^{2}+R^{2})^{\frac{3}{2}} }[/tex]

[tex]B = \frac{\mu_{0} IR^{2}}{4 \pi ((\frac{R}{2} )^{2}+R^{2})^{\frac{3}{2}} }[/tex]

white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density

Answer:

White noise refers to sounds that mask other sounds that might occur naturally in an environment. If you live in a city, for example, white noise could help block out noises associated with traffic. Specific sounds might be used to help encourage sleep regardless of environmental noises.

By electric flux, the electric field is 41.36 x 10⁵ N/C

We need to know about electric flux to solve this problem. Electric flux is the measure of the electric field through a given surface, although an electric field in itself cannot flow. It can be determined as

Φ = E . S = E . Scosθ

where Φ is electric flux, E is electric field, θ is angle of surface and S is surface area.

From the question above, we know that

Φ = 5.20 × 10⁵ N.m²/C

d = 0.4 m²

r = 0.2 m²

because of maximum flux, hence (cosθ = 1)

By substituting the following parameter, we get

Φ = E . Scosθ

5.20 × 10⁵ =E  . π.r²

5.20 × 10⁵ =E . π.0.2²

E = 41.36 x 10⁵ N/C

Hence, the electric field is 41.36 x 10⁵ N/C

D. 4Al + 3O2 → 2Al2O3

Explanation:

Chemical reactions involves the chemical combination of two or more substances called REACTANTS to yield other substances called PRODUCTS. However, in accordance with the LAW OF CONSERVATION OF MASS, the amount of reactants must be equal to that of the products.

To accomplish this, the reaction must be BALANCED. A balanced equation is an equation in which the number of atoms of each element in the reactant side equals the number of atoms in the product side. In this reaction involving Aluminum and Oxygen to give Aluminum oxide as follows:

Al + 02 → Al2O3

Answer:

8.6m/s²

Explanation:

Given parameters:

Initial velocity  = 0m/s

Time  = 5.5s

Distance  = 130m

Unknown:

Acceleration  = ?

Solution:

To solve this problem, we use one of the appropriate motion equations:

       S  = Ut  + [tex]\frac{1}{2}[/tex] at²

S is the distance

U is the initial velocity

t is the time taken

a  is the unknown acceleration

t is time taken

    Since U = 0m/s

      S  =  [tex]\frac{1}{2}[/tex] at²

     130 =  [tex]\frac{1}{2}[/tex]  x a x 5.5²  

     130  = 15.13a

         a  = 8.6m/s²

Mars has a thin atmosphere.

the actual diameter of the object is 1.017×10⁵km

actual diameter, d = any line segment that passes through the center of the circle

angular diameter, θ = the angle that an actual diameter of an object makes.

distance, D= the actual path travel

distance of the object ,D= 1.4 billion = 1.4×10⁹km

angular diameter of an object,θ = 15arc

                            θ  = 15 ×π/ (60×60×180) rad

                                                 [ ∵ 1 revolution = 2π = 360°×60×60]

   Using the relation,

     θ = d/D   {angular diameter = actual diameter/ distance}

     d =  θD

      d =  1.4×10⁹×[15×3.14/(60×60×180) ] km

         =  1.017×10⁵km

Answer:

The value is  [tex]t = 18.6 s[/tex]

Explanation:

From the question we are told that

     The average acceleration of the bicycle is [tex]v = -0.44 \ m/s^2[/tex]

      The initial forward velocity is  [tex]u = 8.2 \ m/s[/tex]

Generally from kinematic equations we have that

      [tex]v = u + at[/tex]

Here v is the final velocity of the bicycle and the value is v = 0 m/s

So

      [tex]0 = 8.2 + (-0.44)t[/tex]

Answer:

[tex]a_{moon}=5.84m/s^{2}[/tex]

Explanation:

In order to solve this problem, we will need to draw a free body diagram of both situations (see attached picture).

So first, we need to find what the mass of the object is. We can do so by analyzing the horizontal movement of the first situation, so we get:

[tex]\sum F_{x}=ma[/tex]

F=ma

[tex]m=\frac{F}{a}[/tex]

so

[tex]m=\frac{15N}{6.4m\s^{2}}[/tex]

m=2.34kg

next, we can analyze the second situation, we will start by analizing the vertical movement so we can determine the Normal force, so we get:

[tex]\sum F_{y}=0[/tex]

[tex]N-W=0[/tex]

N=W

N=mg

[tex]N=2.34kg(1.62 m/s^{2}[/tex]

N=3.79N

so now we can analyze the horizontal movement of the block, so we get:

[tex]\sum F_{x}=ma[/tex]

[tex]F-N\mu _{k}=ma[/tex]

[tex]a=\frac{F-N\mu_{k}}{m}[/tex]

[tex]a=\frac{15N-(3.79N)(0.35)}{2.34kg}[/tex]

[tex]a=5.84 m/s^{2}[/tex]

The infra-red detectors are made from thermocouples soldered to blackened metal plates. These are connected to galvanometers.

A galvanometer measures electric current electromechanically. Early galvanometers were not calibrated, but later models, called ammeters, were, and could measure current flow more precisely.

A galvanometer functions by deflecting a pointer in response to an electric current running through a coil in a steady magnetic field. Galvanometers can be viewed as a particular type of actuator.

The discovery that a magnetic compass needle deflects when near an electric current-carrying wire led to the invention of galvanometers, which was made by Hans Christian rsted in 1820. They were the first tools used to find and gauge minute currents. The apparatus was given the name Luigi Galvani by André-Marie Ampère after the Italian electricity researcher who, in 1791, discovered it.

Explanation:

The first step is to calculate the velocity

= 0.37 m/s

Therefore the time taken for the person to reach the top can be calculated as follows

= 17.4/(0.37+0.541)

= 17.4 / 0.911

= 19.1 secs

Hence the time taken is 19.1 secs

Answer:

when A and B are travelling opposite directions

Answer:

31.25 meters in a time of 2.5 seconds.

Explanation:

Because your question gives a number that is a multiple of 5, that is just begging for us to set a = -g = -10 m/s^2. This is acceleration due to gravity. Then, we have an equation vf = v0 + at where v0 = 25 m/s. Plugging in the earlier known values and letting vf = 0 (when final velocity is zero there is maximum height), we get t = 2.5 s. Then, Delta y = vot - 1/2 gt^2. This gives 62.5 - 31.25 = 31.25 m.

Thus, our answer is 31.25 meters in a time of 2.5 seconds.

*Note: g is more precisely 9.806 m/s^2, but that would lead to more annoying sig figs in our answer so I chose to round to 10 m/s^2 which is common.
