Convection Current
This happens when there is a noteworthy contrast in temperature between two sections of a liquid. At the point when this temperature distinction exists, hot liquids rise and cool liquids sink, and after that streams, or developments, are made in the liquid

Two uniformly charged conducting plates are parallel to each other. They each have area A. Plate #1 has a positive charge Q whil

Marrrta [24]

Answer:5

Explanation:

Given

First Plate has a charge of +Q and area A

Second Plate has a charge of -3 Q and area A

We Know electric Field due to sheet charge is given by

$E=\frac{Q}{2A\epsilon }$

Where Q=charge over the Plate

A=Area of plate

$\epsilon$ = Permittivity of free space

Electric Field Due to Positive charge will always be away from it while for negative charge it is towards it.

Net Electric Field at a point between between the Plates is the superimposition of two electric with direction

$E_{net}=\frac{Q}{2A\epsilon }+\frac{3Q}{2A\epsilon }$

$E_{net}=\frac{2Q}{A\epsilon }$

Net electric Field is towards the negative charged plate

A CD has an initial angular speed of 600 rpm. If the disc stop rotating after 4 seconds, what is its angular acceleration?

Elza [17]

Answer:

-15.708 rad/s^2

Explanation:

First, let us covert everything to the same unit. For me, I find dealing with radians/sec more intuitive, but you can solve it in rpm. We are told that the initial angular speed is 600 rpm and after 4 seconds it stops. Let's convert 600 rpm into radians/sec. To do this, multiply by 2*pi/60. This gives 62.83 rad/s. Now let's review our info:

$\omega_i = 600rpm = 62.83rad/s\\\omega_f = 0\\t = 4s\\\alpha = ?$

Now we look up angular kinematics equations and the equation that has these parameters is

$\omega=\omega_0+\alpha t$

Substitute our values in:

$\omega=\omega_0+\alpha t\\0=62.83\frac{rad}{s}+\alpha *(4s)\\\alpha = -15.708\frac{rad}{s^2}$
