Answer:

The potential between the plates will decrease.

Explanation:

An insulator is usually placed between the parallel plates and is also called a dielectric because it makes the amount of charge a capacitor can accommodate to increase at a particular potential difference.

Furthermore, the dielectric effect will make the electric field of the charged capacitor which is not connected to a source of supply to decrease.

Now, when the battery is removed, the charge Q remains constant and Capacity C will increase.

Formula for the potential difference is here;

V = Q/C

Since the numerator Q is constant and the denominator C increases, it means the potential difference V will decrease

You have a 1.8m long copper wire. You want to make an N-turn current loop that generates a 2.0mT magnetic field at the center wh
NikAS [45]

Answer:

The diameter is  0.022m.

Explanation:

The magnetic field B at the center of the coil is given by

(1). B = \dfrac{\mu_0 NI}{d}

where \mu_0 = 1.26*10^{-6} m\:kg\:s^{-2} A^{-2} is the magnetic constant, I is the current, N number of coils, and d is the diameter of the coil.

Now, if we call L the length of the wire, then it must be true that

\pi dN = L <em>(this says </em>N<em> coil circumferences (</em>c=\pi d<em>) fit into </em>L<em> )</em>

\therefore N = \dfrac{L}{\pi d }

putting this into equation (1) we get:

B = \dfrac{\mu_0 IL }{\pi d^2}

solve for d:

\boxed{d = \sqrt{\dfrac{\mu_0I L }{\pi B} }}

putting in the numerical values

\mu_0 = 1.26*10^{-6} m\:kg\:s^{-2} A^{-2}

I =1.3A

L= 1.8m

B =2.0*10^{-3}T

we get:

d = \sqrt{\dfrac{(1.26*10^{-6})(1.3) *1.8 }{\pi (2.0*10^{-3})} }

\boxed{d = 0.022m}

vitfil [10]
First body:

E_{k_1}=\frac{1}{2}.m.v^2\\&#10;\\&#10;E_{k_1}=\frac{1}{2}.5.v_1^2=\frac{5}{2}.v_1^2

Second body:

E_{k_2}=\frac{1}{2}.m.v_2^2\\&#10;\\&#10;E_{k_2}=\frac{1}{2}.10.(20)^2=2.000 \ J

From description of the task we have:

E_{k_1}=E_{k_2}\\&#10;\\&#10;\frac{5}{2}.v_1^2=2.000 \ J\\&#10;\\&#10;5.v_1^2=4.000 \ J\\&#10;\\&#10;v_{1}^2=800 \ J\\&#10;\\&#10;v_{1}= \sqrt{800} \ J \approx 28,3 \ m/s

Batteries convert chemical energy into electrical energy. It is able to store electrical energy in the form of chemical energy. 
Have you ever seen the two different sides of a battery? One side is often labelled with a positive sign, and the other with a negative sign. Inside the battery are four cells where two processes take place. One process uses electrons, and the other creates electrons. When the electrons flow, it creates electricity. 
Drums convert mechanical energy into sound energy. 
When a musician bangs his/her drumstick on the drum, the motion makes a sound. This movement turned motion into sound.
