A metal ring 4.00 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpend

liq [111]

Answer:

a) 0.21N/C

b) counterclockwise

Explanation:

a) to find the magnitude of the electric field you can use the following formula:

$\int Eds=-\frac{\Delta \Phi_B}{\Delta t}=-\frac{\Delta AB}{\Delta t}$

A: area of the ring = pi*r^2

E: electric field

Ф_B: magnetic flux

In the line integral you can assume E as constant. Furthermore, you calculate the change in the magnetic flux by taking into account that the time interval is 1.12/0.21=5.33s. By replacing in the formula you obtain:

$\frac{\Delta \Phi_B}{\Delta t}=\frac{A(B_f-B_i)}{5.33s}=\frac{\pi(0.04m)^2(1.12T)}{5.33}=1.056*10^{-3}W/s$

$E\int ds=E(2\pi r)=1.056*10^{-3}W/s\\\\E=\frac{1.056*10^{-3}W/s}{\pi(0.04m)^2}=0.21\frac{N}{C}$

the magnitude if the induced electric field is 0.21N/C

b) By the Lenz's law you can conclude that the current has a direction in a counterclockwise

Lithium has 3 protons, 3 electrons, and 4 neutrons. How much is the positive charge of this atom?

yanalaym [24]

Answer:If you add a proton to the atom, it becomes beryllium (atomic number = 4).

It is an ion with a +1 charge, since the number of protons (4) no longer equals

the number of electrons (3).

So you have a beryllium +1 ion - the best answer choice is C.

A Tesla Roadster car accelerates from rest at a rate of 7.1m/s for a time of 3.9s

liberstina [14]

The distance covered is 54.0 m

Explanation:

Since the motion of the car is a uniformly accelerated motion, we can use the following suvat equation:

$s=ut+\frac{1}{2}at^2$

where

u is the initial velocity

t is the time

a is the acceleration

s is the distance covered

For the car in this problem, we have

u = 0 (it starts from rest)

$a=7.1 m/s^2$ is the acceleration

t = 3.9 s is the time

Substituting, we find s:

$s=0+\frac{1}{2}(7.1)(3.9)^2=54.0 m$
