Answer:

-4

Step-by-step explanation: I think of this by turning it to a subtraction problem. 16-12=4. But you still do have to add the negitive symbol

Answer:

-4

Step-by-step explanation:

its easier to think of it as 16-12 then if the negative number is greater than the positive add a negativ esymbol.

Hoped i explained that good enough.

find the flux of the constant vector field v→=3i→ 2j→−5k→ through a square plate of area 25 in the xz-plane oriented in the posi

Readme [11.4K]

The flux across a surface is an indicator of the rate at which fluid is flowing through it when there is a fluid flowing in three dimensions and a surface positioned inside that space.

<h3>What is Electric Flux?</h3>

A feature of an electric field is electric flux. One way to conceptualize it is as the quantity of forces interacting in a specific space.
According to conventional wisdom, electric field lines begin with positive electric charges and conclude with negative charges.
A closed surface's field lines are seen as negative when they are directed into it, and as positive when they are directed out of it.
Every field line that is directed into a closed surface continues through the interior and is often directed outward somewhere else on the surface if there is no net charge present within the surface.
The net, or total, electric flux is zero because the size of the negative and positive fluxes are just about equal.
A closed surface that contains a net charge will have a total flux that is proportional to the enclosed charge, positive if it is positive and negative if it is negative.

! + 3 − 5 = 0; by completing the square

mylen [45]

Answer:

x = 1.19258 and x = −4.19258

Step-by-step explanation:

The given equation is :

$x^2+3x-5=0$

Keep x terms on the left and move the constant to the right side by adding it on both sides.

$x^2+3x=5$

Take half of the x term and square it.

$(3\times \dfrac{1}{2})^2=\dfrac{9}{4}$

then add the result to both sides

$x^2+3x+\dfrac{9}{4}=5+\dfrac{9}{4}\\\\(x+\dfrac{3}{2})^2=\dfrac{29}{4}\\\\(x+\dfrac{3}{2})=\sqrt{\dfrac{29}{4}}\\\\x=\dfrac{-3}{2}+\sqrt{\dfrac{29}{4}}\\\\x=\dfrac{-3}{2}-\sqrt{\dfrac{29}{4}}$

So,

x = 1.19258 and x = −4.19258

Hence, this is the required solution.

Hannah has information about an object in circular orbit around Earth. MEarth = 6. 0 × 1024 kg G = 6. 67 × 10–11 StartFraction m

castortr0y [4]

In order to calculate the tangential speed of the orbiting object Hannah need the distance of the orbiting object to Earth.

<h3>What is the tangential speed of the object?</h3>

The tangential speed of an object is the linear component of the speed, which is moving in a circular path.

In terms of the gravitation constant, the tangential speed can be given as,

$v=\sqrt{\dfrac{Gm}{r}}$

Here, {<em>G</em>} is the gravitation constant, (<em>m</em>) is the mass and (<em>r</em>) is the radius.

Hannah has information about an object in circular orbit around Earth.

The mass of the earth is.

$m_E=6. 0 \times10^{24} kg$

The value of gravitational constant is,

$G=6. 67\times 10{-11}\rm Nm^2/kg^2$

The radius of the earth is,

$r_E=6. 0 \times 10^6 \rm m$

Here, only the distance of the orbiting object to Earth is need to find the tangential speed of the object.

Hence, in order to calculate the tangential speed of the orbiting object Hannah need the distance of the orbiting object to Earth.
