The solution to this ques is available in the image.

Given,

Force= 1N

Mass= 0.11kg

Time= 5sec

Force= mass X accelaration

Accelaration= velocity/ time

Speed=distance/ time

Hence, the speed is 45 m/s and the distance is 225 m.

To get an idea of the size of magnetic fields at the atomic level, consider the magnitude of the magnetic field due to the elect
artcher [175]

Answer:

The magnetic field is 14.08 T.

Explanation:

Given that,

Speed of electron v=2.2\times10^{6}\ m/s

Distance d =0.5\times10^{-10}\ m

Suppose we need to find the magnetic field at  the location of the proton

We need to calculate the magnetic field

Using formula of magnetic field

B = \dfrac{\mu_{0}I}{2r}....(I)

Using formula of current

I=\dfrac{q}{T}

Using formula of time

T= \dfrac{2\pi r}{v}

Put the value of current and time in equation (I)

B=\dfrac{\mu \times q\times v}{2\pi r\times2r}

Put the value into the formula

B=\dfrac{4\pi\times10^{-7}\times1.6\times10^{-19}\times2.2\times10^{6}}{4\pi\times(0.5\times10^{-10})^2}

B=14.08\ T

Hence, The magnetic field is 14.08 T.

an object ends up at a final position of x=-55.25 meters after a displacement of -189.34 meters after a displacement of -189.34
Rzqust [24]

-244.59meters

Explanation:

The initial position of the object is located at -244.59meters from the origin.

Displacement is the distance from the start to finish of a body.

Final position of the body is at x=-55.25 meters

 Amount of displacement is -189.34meters;

let us represent this by a coordinate system in the negative x - direction;

                                                                              Origin

Start                                       finish                            0m

   -a                                             -x

                                              -55.25meters

               displacement

                -189.34meters

Position -a is about 189.34 in left direction from 55.25; this gives:   55.25 + 189.34 = -244.59m in the left direction
