The intensity of the magnetic force exerted on the wire due to the presence of the magnetic field is given by
F=ILB \sin \theta
where
I is the current in the wire
L is the length of the wire
B is the magnetic field intensity
\theta is the angle between the direction of the wire and the magnetic field

In our problem, L=65 cm=0.65 m, I=0.35 A and B=1.24 T. The force on the wire is F=0.26 N, therefore we can rearrange the equation to find the sine of the angle:
\sin \theta= \frac{F}{ILB}= \frac{0.26 N}{(0.35 A)(0.65 m)(1.24 T)}=0.922

and so, the angle is
\theta=\arcsin(0.921)=67.1^{\circ}

The angle between the wire segment and the magnetic field is about 67°

\texttt{ }

<h3>Further explanation</h3>

<em>Let's recall </em><em>magnetic force on conducting wire</em><em> as follows:</em>

\boxed{F = B I L \sin \theta}

<em>where:</em>

<em>F = magnetic force ( N )</em>

<em>B = magnetic field strength ( T )</em>

<em>I = current ( A )</em>

<em>L = length of wire ( m )</em>

<em>θ = angle between magnetic field and the wire segment</em>

Let's tackle the problem now !

\texttt{ }

<u>Given:</u>

length of wire = L = 65 cm = 0.65 m

current = I = 0.35 A

magnetic field strength = B = 1.24 T

magnitude of force = F = 0.26 N

<u>Asked:</u>

angle between magnetic field and the wire segment = θ = ?

<u>Solution:</u>

F = B I L \sin \theta

0.26 = 1.24 \times 0.35 \times 0.65 \times \sin \theta

\sin \theta = \frac{200}{217}

\theta = \sin^{-1} (\frac{200}{217})

\boxed{\theta \approx 67^o}

\texttt{ }

<h3>Conclusion:</h3>

The angle between the wire segment and the magnetic field is about 67°

a cart's initial velocity is +3.0 meters per second. What is its final velocity after accelerating at a rate of 1.5m/s2 for 8.0
Andreas93 [3]

The final velocity is +15.0 m/s

Explanation:

The motion of the cart is a uniformly accelerated motion (=at constant acceleration), therefore we can use the following suvat equation:

v=u+at

where

v is the velocity at time t

u is the initial velocity

a is the acceleration

t is the time

For the cart in this problem, we have:

u = +3.0 m/s (initial velocity)

a=1.5 m/s^2 (acceleration)

t = 8.0 s (time)

Substituting, we find the final velocity:

v=3.0+(1.5)(8.0)=+15.0 m/s

What is the strength of the electric field 0.1 mmmm below the center of the bottom surface of the plate
Aleksandr [31]

Complete Question

A thin, horizontal, 12-cm-diameter copper plate is charged to 4.4 nC . Assume that the electrons are uniformly distributed on the surface. What is the strength of the electric field 0.1 mm above the center of the top surface of the plate?

Answer:

The  values is  E =248.2 \  N/C

Explanation:

From the question we are told that

   The  diameter is  d =  12 \  cm  =  0.12 \ m

    The charge  is  Q =  4.4 nC  =  4.4 *10^{-9} \  C

    The  distance from the center  is  k =  0.1 \ mm   =  1*10^{-4} \  m

Generally the radius is mathematically represented as

        r =  \frac{d}{2}

=>     r =  \frac{0.12}{2}

=>       r =  0.06 \  m

Generally electric field is mathematically represented as  

       E =  \frac{Q}{ 2\epsilon_o } [1 - \frac{k}{\sqrt{r^2 +  k^2 } } ]

substituting values  

      E =  \frac{4.4 *10^{-9}}{ 2* (8.85*10^{-12}) } [1 - \frac{(1.00 *10^{-4})}{\sqrt{(0.06)^2 +  (1.0*10^{-4})^2 } } ]

     E =248.2 \  N/C

20. Using the picture, how many neutrons does lithium have?
Igoryamba

Answer:

No. of Neutrons = 3

Explanation:

The atomic number of Lithium is given as 3 in the symbol while the mass number is given as 5.941 which is approximately equal to 6.

Mass Number = No. of Protons + No. of Neutrons = 6

Atomic Number = Number of Electrons = No. of Protons = 3

Therefore,

Mass Number - Atomic Number = (No. of Protons + No. of Neutrons) - No. of Protons

Mass Number - Atomic Number = No. of Neutrons

No. of Neutrons = 6 - 3

<u>No. of Neutrons = 3 </u>
